- In this video: Jeff has run up against an obstacle to finishing a project, can he use a speedbor/paddle bit to bore a 15/16" hole into 3/4" thick solid aluminum bar? Lets find out.

Fantastic. I am looking to make a jig in 3/4" thick aluminum, with 5/8" inch holes all the way through, and a 3/4" hole only 1/8" down, perfectly centered with the 5/8" holes. I am going to drill a pilot like you did. Then use the 3/4" spade bit to bore 1/8" deep "recess". Then complete with a 5/8" metal bit through the stock.
I am simply trying to make a jig that will perfectly center 5/8" OD tubing onto a 3/4" disc, leaving a *near perfect* 1/16" lip.
Your video here could not have been more perfect for me to determine if I could do this in our shop, as opposed to having a machine shop do it. Thank You!
I've cut 1" plate aluminium on a cheap table saw and also on a cheap vertical bandsaw. Both intended for wood, and I didn't even bother with lube.
Worked alright!
I've also cut fine finned heatsink on that tablesaw with a sharp blade. That worked amazingly well.
at 5:09 when you started to drill, the table moved down because you didn't take up the slack in the screw feed. If you lower the table, always turn the screw feed back up a bit so the table stays in the same place.
Nice video.
This is one of those thing that you must learn by experience. Love it.
i have used regular non carbide 3/4" round off router bits b4 after welding tubes to a plenum on a sheet metal intake and i was blown away by the results had to actually rough up the surface slightly to help the air move with little more turbulence
Great experiment, never thought of it. Love to see other paddle comparison.
Good, I will try this. Thanks!
Awesome vid
Also not recommended but I cut 1/8 to 3/16 aluminum plate in my 10" table saw. Yes it's a white knuckle moment! You must use a reasonably slow and steady feed rate and make sure the plate is tied down REAL secure. Oh, and use a good blade with beefy carbide teeth.
i dont know if thats something you do a lot or anything, but make yourself a sled for the table saw, and add a 6" strip of Plexiglas over the blade to stop the shavings from flying up and more out to the sides. works really well.
Daniel Napast you can buy blade for table saws to cut aluminium.
@@danielnapast4955 I was actually always taught that, when cutting metal on the table saw, you actually want the opposite in terms of blade height, meaning you really want the blade up much much higher than if you were cutting the same thickness of wood. Some people I know just crank it all the way up to its max height when cutting aluminum. I can't remember exactly why now but when it was explained to me, I remember thinking oh yeah that totally makes sense.
as usual the woods are full of after-the-fact experts telling the video man what he did wrong...but I think this experiment was a success.
cool , thanx , another new thing to be able to use in the knowing bin collection of usefull stuff ;-)
Thanks. This is exactly what I needed to know today. Do you think you could have gone faster if you used coolant? 4:30 is quite a long time. Any other ideas that might speed up the process?
The problem with faster speeds, if there is any runout at all the it will start to vibrate a lot and make the hole slightly out of round.
@@jeffreysanto Thanks. That makes sense. I'm going to give this a try tonight. Bought a brand new Diablo bit so it will be plenty sharp.
I liked this.
I have cut them into shapes too machine recesses for O rings and counter sink large bolt heads flush. Went with medium speed and low feed with bits as sharp as I could get them.
Whatever it takes to gets the job done when you are in a pinch :)
Crazy...but interesting... didn't think it would work...or at least..wipe out the bit... but cool....You Lived !!!!.....lol
But what size did the hole end up being?
A spritz of WD40 would go a long way toward keeping your bit and workpiece cooler, and improving the surface finish. Ideally you use plain ol' kerosene as a cutting fluid for aluminum. I've used carbide router bits on 6061-T6 aluminum many times with great success. I did expect an explosion during this video... Its tough enough to drill construction lumber with a spade bit and not get hurt.
Interesting about using kerosene as a cutting fluid for aluminum, I'm going to give that a shot the next time I have an opportunity. Thanks for the tip :)
Jeff Stewart I would agree with that. Spade bits grab hard enough in wood I thought it might be even worse in metal. Also, a little lubricant would most likely make a big difference.
I was going to say the same about adding some oil.
I worked heavy construction. ..we found those paddle drills would go though sheet stainless like butter where a normal drill would break... who knew??
if you put lube on it...won't work
Interesting
How do I mark of "STRAIGHT lines" prior to drilling 1/4" 1000mm by 1000mm Plate aluminum?
Hey do you have a video on how to drill through solid lead successfully with a 1/8" bit or smaller? It's nearly impossible on every try I have seen.
This peeked my interest, I've never tried to drill lead before... what happens? does the drill bit break? How think of a piece of lead are you trying to drill? I love trying to troubleshoot problems and if I can help you and solve a riddle in the process I will even make a video on it.
i wonder how well it would work if you slowed it down a bit, locked the table, clamped the vise, shortened the spade bit as much as possible, and used some WD40 or something. but hey, thnx for sharing :)
The table lock broke, just fixed it about a week ago... as for the rest, this is me without enough coffee to function. At least I entertain myself :)
Jeffrey Santo you just got me curious how nice of a hole one could get using that bit is all. :P
I'm going to be shooting a video doing the same thing with a 7/8" Forstner bit once it comes in. I plan to drill another hole with the paddle bit as well, this time in the mill. I'm interested to see if there will be any major difference.
I use forstner bits to drill 1/8" aluminum plate. Slow speed, sharp bit, and a little fluid.
I reckon the forstner bit will break at its neck, but hey I could be wrong.
what do the hole in the "spade" do is it for hanging the bit on the wall ?
I am honestly not sure, not all brands have the hole in it. It could be there to aid in a step of the manufacturing process, but that is just a guess.
Paddle bits work very well in alum.. So do Forstner bits....
Classic Jeff. Square peg, round hole.
You're supposed to go slower for bigger bits & faster for smaller bits in metal work. Aluminium is soft like brass though & can snag the bit. A bit this big shouldn't be a problem though. They're called spade bits over here & if made out of the right material they will cut through metals just like a regular hss twist bit does. In fact they're one of the easiest types for toolmakers to make for one off special jobs in metal work /mass component contracts etc. That's obvious just by looking at it though. You got away with it because steel is harder than aluminium plain & simple. You could probably sharpen that bit up for wood use again no problem.
let's see a forstner bit next!
Bobby Patton Jimmy DiResta used one to bore through a fairly thick piece of aluminum with great success.
yep aluminum drilling or cutting works much faster and cooler with the right lubricant. you can also use a paddle bit to drill through sheet metal. if it is a piece than can be done on the drill press try to put some wood underneath. another thing i learned from a friend and coworker who only had a grade school education. you can learn a lot from a dummy.
Run the bit fast, use cutting oil and slowly push in and you will be just fine.
Hardwood Knots and burl is uneven and harder than Aluminum, Brass and Copper,
if it can cut Hardwood Knots and burl it will cut Aluminum, Brass and Copper,
Copper work hardens so you need to cut aggressive but not so aggressive as to bind.
Aluminum goes molten easy coolant is required, go slow if you don't use coolant..I could just see the shaft bend on the drill and doing a gut shot on his hand ..
A heavy leather or similar shop apron would help
You can cut metal with a mitre saw blade
I always heard run bit backwards to cut metal.
johnny rizzo I flip the blade on the skill saw for tin roofing.
you need les speed with aluminum it hardens wen it gets hott !!!
I use the cheap chinesium steel to drill through aluminum all the time
2:33 😂
aluminum is soft enough but you still should of used some kind of lube
Mike Chilinskas fuck you
fuzzy wuzzy is that a promise?
Jon Favreau?
Drill press probably can't go as slow as you need...
I dunno. My drill press goes down to 220 rpm, which is slow enough to drill about a 2 inch hole through mild steel with a twist bit.
DSCKy aluminum has a high cutting speed he's not Drilling through Steel
Next time lay a block of wood under the stock then you dont have to flip
WHY?
Because I could... that and rather than needing to run out, buy a drill bit first thing in the morning and start again I got a paycheck.
lol faster you can go the better?
I run aluminum jobs that if I were to increase spindle speed by 20% i'd be breaking tools
LOL and how fast is your spindle speed now? If your already running at a high RPM of course increasing it by 20% could be catastrophic... I love people like you man, you crack me up.
Nicholas Washburn mm
my table saw cuts more aluminium than wood ,& not just thin shit
lol @ drlling dirty holes...childish i know but funny.
Eat protection, respirator, gloves.
Um... eat protection? First the act drilling through aluminum does not produce enough noise to require EAR protection. Second, you NEVER wear gloves while using machine tools. Third there are no fumes why the hell would I need a respirator?
Go troll someone else you uneducated putz. Ain't nobody got time for you.
watched one of my buddies use one of those bits to try to drill through ceramic tile while pulling an all nighter on a job. Yea that didn't work but it will drill through your thigh without a problem.
wd40 and slow down the speed man
