@@lewisrichards6572 Pretty much any decent hardware store should carry a four bladed SDS masonry bit. Or if you want to spend some $ Hilti. Two bladed ones just don't produce a round enough hole

From a machinist standpoint. A two flute drill bit will actually drill a triangular shaped hole. The four flute drill bit will drill a more round hole. When using dial or digital calipers to measure, you apply light pressure. Great tests though. I enjoyed your video and watched a few more despite having no interest in climbing.
@@thth1451 imagine one corner of the chisel sticking. The other corner will will sweep out an arc until it sticks, and the first corner sweeps out another arc. This pattern will continue, with the sticking points forming three lobes. The diameter of pin that will fit will be different than expected (smaller?) and the bearing surface will be smaller. With four corners, I imagine you'd get a somewhat pentagonal, but overall more round, hole.
Way back me and my dad Rowland Edwards invented the extractable bolt idea for climbing... It was called the E-fix, later to evolve into the ENP. The major problem with removable bolts that are repeatedly used within the same hole is "waxing", a layer of metal is deposited inside the walls of the hole, so much so we found we could literally pull the bolts out by hand! Anyways, removable bolts should be a one use only in them holes. Great videos, great channel. Get well soonest Bobby. Saludos from Spain. M
Used in rope access on building sides and roofs for re belays, deviations. Great for near the ocean city jobs as can be removed to protect from corrosion . A lot less obtrusive than fixed hangers.
A mate of mine who I worked for in rope access told me they only use them in special high strength concrete. I never used them personally, only the big Petzl glue in ring anchors and they were also in concrete. Super Great video as always!
Thanks for the great video! I’ve heard of these being used wonderfully in caving, and that’s how I plan to use them. Very useful in situations where you have no good natural anchor, or need something like a rebelay. Passing rope protectors can be a hassle and risk moving, being dropped, etc which then can expose the rope to sharp rock which is super dangerous in caving. Normally I prefer natural anchors and a rope protector, but sometimes it’s way too tedious having several rope protectors and it’s not ideal. What I like about these is that I can, if needed, drill in a spot for a rebelay or anchor, enter quickly, and leave while keeping the bolts with me and leaving nothing but a bit of dust and the hole. If we want to return frequently or make the cave accessible to future adventurers we can ideally use the same hole as a glue in bolt so then future cavers can enter and enjoy with minimal gear- just carabiners and rope. These are great though because if the cave doesn’t continue, ie it’s just a random drop to nothing, then we don’t leave anything behind but a little hole. Again, I almost always would prefer natural anchors with rope protectors like Petzl Protec, but this is in my mind now for situations where we really don’t have good or safe natural anchors and I expect it to continue so the temporary Petzl pulse is a great thing to use until one day someone decides to glue it. Thanks again!
I was climbing at Lion's Head Ontario Canada and it's a sea cliff with a top-down approach. My friend had the Petzl Attache and was loaded when she screwed the safety close. Had to run back to the car and get a pair of plyers. Now I always close the gate unloaded. Still love the Attache, it's one of the best all around lockers I've ever used.
I don’t even highline, slack line, or climb, but your videos are cool man. You never know when the info will come in handy. You gained a new subscriber

Used them in industrial rope access to access cliff edges for scaling rockfall mitigation. Had no issues. I do wish there was a semi- permanent sleeve- type device for repeated use. Found a bit from hilti that worked perfectly, pricey tho.
We use them in civil protection rope access, i guess with the goal to quickly enter locations to save people, leave and go next with less material to carry, and when training so we can quickly remove bolts and seal holes without having to restock bolts regularily.
Nice testing guys. Thanks for the video. I can see why they don't want you to lead over those. If the carabineer flips over the top as you climb past it and take a fall.. You can break that quick release.
Haven’t used these, thinking about picking some up. We use the climbtech removable bolt system, they were some of the first. In their testing they claim the substrate will break before the bolt.. might be worth a try..-------- Our use case: redirecting in industrial setting, placing anchors for temperorary operations.. only for static loads, only for double rope system. Making a “collar” slow drilling at first is key, going straight in, and blowing out the hole are key. Dust “lubricates” the hole and must be cleared out. Great vid! Keep it up!
Used them once while retro bolting. My partner had a few. Worked well. However, and considering my limited use and this video (thank you), price seems to be the only reason why I wouldn't use them again. Dollar Titens for the win.
Great to see these tested! I use them a lot for birds of prey research to access nests etc., where one would not want to leave anchors (for obvious reasons) once done with the work. The study areas are often in National Parks where permission for bolting may be time consuming, and this apparently doesn’t count. I printed rock coloured rubber stoppers to plug the holes, which, allows me to use the same holes over multiple seasons (If I can find them again ;).
Have you tried the 7.5mm Raumer Multi-Monts screws? Very similar concept in terms of easy placement (no need for impact driver) and removable. Much cheaper!
Fyi the atache barrel can be loosened with an 8mm camp quicklink. As you unscrew the link, Place the atache barrel so that the link barrel unscrews into / hits the atache barrel. Then use the link as a wrench
These bolts can turnout pretty handy for drilling routes up the wall. in very negative angles they are lifesavers, at least we've been using them with this purpose on our very solid sandstone, and it has been pretty satisfying. Don't about disclaimers for that type of use, but I guess there is a point when it's all about mitigating risk, not eliminating it. So, in that case, it's a very helpful piece of tool to have in-hand.
TH-cam brought me to your channel yesterday and today I got to watch a brand new video! That’s because I subscribed with notifications turned on! What a beautiful piece of engineering!

Great video! Just a friendly heads up, (and TH-cam community, feel free to correct me if I'm wrong), but calipers shouldn't be squeezed hard, you end up getting a smaller reading based on the mechanical flex/"slop" in the calipers, and your dimensions are artificially reduced. Instead, your calipers should be snug, firm but gentle. Does this matter for most cases? Maybe not, but when we're talking about a tenth of a mm, every little bit matters.
Thanks guys, I've used these for years for not just rap anchors. at first I was like ugh why do you guys keep breaking these things brand new? there's little point in that as they're rated so they'll be fine if installed properly. But the second test is something I've had happen and it's great to see the results. They're expensive but the main advantage is ease of installation. -They mean you don't need to carry as much gear with you if doing recon, eg a temp anchor where otherwise you might need to bring an impact driver to put in concrete screws -for things you might to back to periodically, no need to use stainless anchors for temporary points, just plug these in and go -you can do guerrilla sport sends (though not recommended by petzl, obvs) of a project without putting in the bolts -they make aiding and access with bolt lines a breeze as you don't need to hammer and tighten with different tools plus if you hunt around for a good deal you can get them for like AU$50
Love this! I use these in a few canyons in Ouray. We use them mostly for handline anchors and redirects as most of our redirects are only needed during high water.
The only time I’ve seen these used was when josh and Charlotte (cold house media) were bolting a mega prow in Peru. They used it to set the rappel line to begin the top down bolting
at 4:30 you said something "opposite". IF you see the little GAP you survive. You die if you DON'T see it. nonetheless, I'm a huge fan of you work. I've learned so much thanks to your videos. keep it up. Cheers from Italy
Before covid, these bolts were around 50$...with the explosion in outdoor gear they must have gone up...I definitley can see a value in these bolts where you are worried about thieves, don't wanna leave responsibility for someone's else's climbing failure, or leave no trace for multiple reasons legal or illegal lol...Toolless feature is what makes it great though. I agree with Bobby though if you are able to have a bunch of gear with you
Looks to me like the machining marks in the hanger are due to the matching anti-rotation feature on the bolt. Love the free sub btw, been rocking it for a while now.
We have. Check out the bolt buster chart at Slackline.com. They are our standard for testing hangers. So far we haven't found a hanger currently in production that is stronger than a 3/8" by 4" plated steel Titen HD in cincrete or harder medium. They achieve lower values in soft sandstone.
Yeah we know you're gonna go whip on it Ryan, you can't fool us. Definitely seems like it could be used in aid climbing in some way, might be cleaner just to have the holes with no hardware, or to replace a gear anchor location.
Seems useful if you needed to develop a sport climbing route on lead, but wanted to equip it with glue in bolts (cause sandstone). You could lead up with these and then replace them with glue-ins on the way down.
Great video, so happy to get to see these breaks. Stronger than I expected. I currently use climb tech Removable Bolts, always been curious about these. Have you used the climb tech ones?
I used them once for a highline show between two buildings, 3 or 4 of them on each side in concrete I think. They were all pulling on the side and it was bomber 10/10 would whip.
Hi Guys! are you going to do an update test? The new Coeur Pulse 2023 model has a spinning hanger and a tightening knob that is supposed to not get stuck.
Start using them for Canyoning Guiding; perfect for setting up temporary anchors for guided rappels and handlines,etc. The x bits are expensive, and the bolt could be hard to retrieve when in wet situation.
We tend to use concrete screws alot in aid climbing in caves. But then you also have to carry a driver which is just one more thing hanging off you. We keep discussing these but have never used them in my group, its great to see a test!
Not sure if someone said this already, but I bet they say not to lead climb with them because of the head snapping off when loaded. A draw could flip right over and get stuck but not with a static load in the hanger... maybe a water bottle?
The Titens (I too use the 1/4" PS ones for temp anchors) are super cheap HOWEVER they require you to haul along an impact wrench, socket etc. Not exactly light. I could see using these for areas where saving weight is helpful. The other area would be positioning bolts on route. Setting a Titen on steep terrain with an impact wrench isn't exactly easy...
You should try Raumer Multi-Monts screws (7.5mm). They are set by hand easily with a ratchet. If you're bolting aboveground, you could use the SDS+ Impact adapter onto your roto-hammer. Cave Exploration Society sells them and Ryan has an affiliate link here: www.slackline.com/shop :)
Hi Ryan, we were thinking of getting 6 of them as we get a discount at a local store. The idea was to use them to rig highlines in protected areas. Are they ok to use for highlining as I just heard you say they are advertised only for rappeling?
I am curious if you tapped the rock with a hammer, before placing them? Granite is not supposed to fail like that, if you hear the “ping” sound from the rock when you hit it with a hammer. I was part of the 2.9km project in Senia (Norway), where they worked like a charm! In the high wind the line was exposed to 22kn equalized between 3 of them 💪 they are still being used I think. Cool video thank you!
Non climber here. Don't know jack, just enjoy watching it. So, just watched the first pull. That carabiner is nuts. I'd think it would break or at least bend with that much force, especially concentrated all on one point. What's the force they can withstand?
How would these be for lead bolting when you have to drill from a climbing stance, much quicker to get in than a normal bolt, then climb to the next stance, put another one in, down to replace the previous one with a proper bolt, continue as above?
I wonder if it’s for high angle rescue? Might be useful for the tripods or additional anchors. I’ve seen double rope for rescue. But that was 5 yrs ago when I took rescue tech.
Mr. Hutton describes his current system (one-dollar bolts) for temporary/removable bolts. Having done the testing of the Coeur Pulse, I wonder if he had any reaction/thoughts on situations where he'd consider it a worthwhile alternative?
Hey there! Has anybody tested those in wood? I know they're not made for this, but I was wondering if that would hold up supergoodenough or if I'd die hanging myself off those felling trees or climbing along wooden roof beams...
@@HowNOT2 sure but that's also the case for any other application. I think the all in one piece factor does improve, even if only slightly, the speed at which one can install these Another possible advantage of this not tool method is the safety it provides when working above people/traffic when you can't set up an exclusion zone at the bottom, the less actions and pieces you have to assemble the anchor the safest This same idea is spreading in the entertainment rigging, steel baskets are more and more made of a rigging ring at one end of the steel cable and a hook at the other end, in replacement to shackles that you have to unscrew while there are other stagehands working beneath the riggers.
@@HowNOT2 Yes, but for insurance puposes, legal BS, etc, they might need to be certified for use as PPE, which is probably biggest advantage Petzl has over concrete bolts
Hi I was working for Metaltech b.v. in Weesp. They make (with milling machines) extreemly high cuallity parts for creuse ships that moostly creuse the ocean and all parts ar mede of stainless 316L. So I dont really get why titanium? Just extra fancy?
There are other chemicals at play from the rock and vegetation (among other things) that when combined with ocean spray can create a condition called Stress Corrosion Cracking. David Reeves over at cragchemistry.com is the expert. Some areas in the Caribbean, Mediterranean and South East Asia have well documented histories of stainless bolts failing.
Impressive but I would never pay 70 for them thats so expensive. And do you still make instant coffee? Going on a backpacking trip and thought I'd grab some.

Yep, I found em on the lowes (central US hardware store) website in like 5 seconds typing in "12mm rebar cutting masonry bit"
Its gratifying to see people that put their lives on "the line" when they play on what they test.

Yeah we know you're gonna go whip on it Ryan, you can't fool us. Definitely seems like it could be used in aid climbing in some way, might be cleaner just to have the holes with no hardware, or to replace a gear anchor location.
thank you for your service
Test the two fluke vs four fluke drilled holes with your standard selection of bolts for bolt busters!
In Germany, these are available for 40€ straight (taxes included) = 43$.
Seems useful if you needed to develop a sport climbing route on lead, but wanted to equip it with glue in bolts (cause sandstone).
You could lead up with these and then replace them with glue-ins on the way down.
You guys should get the slow mo guys for some silly high fraim slow mo
Pretty impressive strength.
Great video, so happy to get to see these breaks. Stronger than I expected. I currently use climb tech Removable Bolts, always been curious about these. Have you used the climb tech ones?
I used them once for a highline show between two buildings, 3 or 4 of them on each side in concrete I think. They were all pulling on the side and it was bomber 10/10 would whip.
Nice!
French highliners also used them to rig in touristic caves.
Hi Guys! are you going to do an update test? The new Coeur Pulse 2023 model has a spinning hanger and a tightening knob that is supposed to not get stuck.
When they get stuck in limestone you can just sell your home to replace them.
Holy shit, those are strong AF
Start using them for Canyoning Guiding; perfect for setting up temporary anchors for guided rappels and handlines,etc. The x bits are expensive, and the bolt could be hard to retrieve when in wet situation.
Love how he flips the bolt at the end!
47kn! Not bad for a removable bolt... Wow
To my knowledge Pulse are used by cavers for aid climbing. Driling holes as they go up but not leaving any gear behind.
Just got out of a cave last night, we used cheap 5/16th galvanized bolts and remove hangers and smash the stud in. Seems expensive.
@@HowNOT2 I used it in caves for every other hole
We tend to use concrete screws alot in aid climbing in caves. But then you also have to carry a driver which is just one more thing hanging off you. We keep discussing these but have never used them in my group, its great to see a test!
Not sure if someone said this already, but I bet they say not to lead climb with them because of the head snapping off when loaded. A draw could flip right over and get stuck but not with a static load in the hanger... maybe a water bottle?
The Titens (I too use the 1/4" PS ones for temp anchors) are super cheap HOWEVER they require you to haul along an impact wrench, socket etc. Not exactly light. I could see using these for areas where saving weight is helpful. The other area would be positioning bolts on route. Setting a Titen on steep terrain with an impact wrench isn't exactly easy...
Great points.
You should try Raumer Multi-Monts screws (7.5mm). They are set by hand easily with a ratchet.
If you're bolting aboveground, you could use the SDS+ Impact adapter onto your roto-hammer.
Cave Exploration Society sells them and Ryan has an affiliate link here: www.slackline.com/shop
:)
you have the most intelligent way of asking for a sub. the first time I heard you say it I clicked the sub button because you earned it with that haha
Hi Ryan, we were thinking of getting 6 of them as we get a discount at a local store. The idea was to use them to rig highlines in protected areas. Are they ok to use for highlining as I just heard you say they are advertised only for rappeling?
Keep the tech talk, dont change anything!
I have two screw lock petzl ok caribiners and they will lock shut easy with just fingers and I have to use pliers to open back up
Amazing! Great video
You get a better measurment with calipers if you hold them normal to whatever you are measuring instead of parallel.
I am curious if you tapped the rock with a hammer, before placing them? Granite is not supposed to fail like that, if you hear the “ping” sound from the rock when you hit it with a hammer. I was part of the 2.9km project in Senia (Norway), where they worked like a charm! In the high wind the line was exposed to 22kn equalized between 3 of them 💪 they are still being used I think. Cool video thank you!
Yeah we got a nice solid sound. It drilled like hard granite too. Other bolts that we tested right there failed well above MBS.
@@bobbyhutton1989 16:33 it looks a bit flakey to me, but hey- I haven’t done 1000 breaktest
it's holding..IT'S HOLDING..oh,it's gonna blow.
hey ! do you think you can test the Petzl Pulse 8mm ?
Non climber here. Don't know jack, just enjoy watching it. So, just watched the first pull. That carabiner is nuts. I'd think it would break or at least bend with that much force, especially concentrated all on one point. What's the force they can withstand?
Insane content mate!
How would these be for lead bolting when you have to drill from a climbing stance, much quicker to get in than a normal bolt, then climb to the next stance, put another one in, down to replace the previous one with a proper bolt, continue as above?
Yo! Great info and testing! I wonder what the alternative bolts that Bobby shows @07:36 are called exactly or where to buy them! THX a Lot

I wonder if it’s for high angle rescue? Might be useful for the tripods or additional anchors. I’ve seen double rope for rescue. But that was 5 yrs ago when I took rescue tech.
I know l am late to the game here but didn't trango or fixe make a tubular cam that went into bolt holes for similar purposes?
Free subscription!!!! Woooo!
How’d you find drilling with a 4 blade drill piece rather than a 2? Any noticeable difference when drilling? Was it quicker?
We generally find that 4 point bits do drill faster than 2 point ones.
Do u guys use a level to help keep the drill perpendicular whilst drilling, especially for these removable bolts?
What's the beat at the end of your vids?
Where in the US can you buy the 12mm bits?
Sauce on 1$ bolts? Just looking for a general idea of that type of thing.
The diameter of a drill does not, typically, equal the diameter of the hole produced.
Mr. Hutton describes his current system (one-dollar bolts) for temporary/removable bolts. Having done the testing of the Coeur Pulse, I wonder if he had any reaction/thoughts on situations where he'd consider it a worthwhile alternative?
I would use them in a situation where someone else was buying the bolts.

Used for installing split ac units in a high rise apartment on Reddit.
Easiest way to undo a stuck carabiner is to weight it again and loosen whilst weighted. Pliers not necessary.
Or buy quality carabiners, ha.
We use them a lot buds
Would you please test them on an equalise anchor
Hey there! Has anybody tested those in wood? I know they're not made for this, but I was wondering if that would hold up supergoodenough or if I'd die hanging myself off those felling trees or climbing along wooden roof beams...
Why can you only use it for repelling? Is Petzl worried about getting sued?
It's not designed for dynamic loads, i.e, "don't fall on it." Hanging from it is fine.
Could they possibly be useful in some rescue scenarios ?
concrete screws would work just as good probably
@@HowNOT2 sure but that's also the case for any other application. I think the all in one piece factor does improve, even if only slightly, the speed at which one can install these
Another possible advantage of this not tool method is the safety it provides when working above people/traffic when you can't set up an exclusion zone at the bottom, the less actions and pieces you have to assemble the anchor the safest
This same idea is spreading in the entertainment rigging, steel baskets are more and more made of a rigging ring at one end of the steel cable and a hook at the other end, in replacement to shackles that you have to unscrew while there are other stagehands working beneath the riggers.
@@HowNOT2 thanks a lot for your videos by the way, you guys put up a lot of work!
@@HowNOT2 Yes, but for insurance puposes, legal BS, etc, they might need to be certified for use as PPE, which is probably biggest advantage Petzl has over concrete bolts
Hi I was working for Metaltech b.v. in Weesp. They make (with milling machines) extreemly high cuallity parts for creuse ships that moostly creuse the ocean and all parts ar mede of stainless 316L. So I dont really get why titanium? Just extra fancy?
There are other chemicals at play from the rock and vegetation (among other things) that when combined with ocean spray can create a condition called Stress Corrosion Cracking. David Reeves over at cragchemistry.com is the expert. Some areas in the Caribbean, Mediterranean and South East Asia have well documented histories of stainless bolts failing.
What type of bolt is using bobby 1dollars screw?my English are not so good so if you could be certain,thank you
Simpson Strongtie Titen HD
Shoot, I was hoping you would test the 8mm version
I believe the 4 bladed bit is called a cruciform bit
12/10 WOULD WHIP!
What were the ones Bobby used
Impressive but I would never pay 70 for them thats so expensive. And do you still make instant coffee? Going on a backpacking trip and thought I'd grab some.
How strong are normal lag bolts?
