SDS vs SDS Plus vs SDS Max | What Is Right For You?

- SDS-Plus vs. SDS-Max - The SDS system has been used in Europe for a long time and has made it way over to the USA. People still question the differences between the different style slotted bit connection system. The name SDS comes from the German "Stecken - Drehen - Sichern" (Insert - Twist - Secure). In German-speaking countries, the back-formation "Spannen durch System" (Clamping System) is used, though Bosch uses "Special Direct System" for international purposes. The SDS system was designed by Bosch in 1975. The SDS chuck system was the original with SDS Plus being an improvement on the original SDS system, but remains compatible with SDS bits, and is now the most commonly seen on the market. SDS Max is designed for the heaviest masonry work and is not with SDS/SDS+ bits.
The difference in the bit is in the size, not necessarily in how each connects. While all three are shaped slightly different, the size is what separates the SDS+ from the SDS Max. SDS and SDS plus are 10 mm diameter - and interchangeable. SDS Max is 18 mm in diameter. That might not sound like much of a difference, but it is significant.
SDS & SDS Plus
SDS is about phased out and SDS Plus is what you will see in most stores. Both are used with carbide drill bits from 5/32” to 1-1/8” and thin wall carbide core bits up to 4”. There are also several types of smaller chipping and chiseling bits that work extremely well with standard SDS Rotary Hammers. In the big box stores, you will often find smaller sets of these bits along with longer bits sold singularly. The rotary hammer drills are listed in their description with the max capacity right in the title such as 1” SDS-Plus or 1-1/8” SDS-Plus. These maximum sizes are solid carbide bit capacities and should be considered when purchasing a new rotary hammer drill. While a 1-1/8” bit will fit in a ¾” SDS-Plus Rotary Hammer Drill, it is not recommended and it will be underpowered. If one was to drill 1-1/8" holes all day with a 1-1/8" SDS-Plus Rotary Hammer Drill all day, they too would find it underpowered. Think of this as a max towing capacity on a truck, running at max capacity is never going to give the user the best experience and half capacity is much better for the tool and the user.
SDS Max
SDS Max Rotary hammers are used with carbide drill bits 1/2” - 2”, thick wall carbide core bits up to 4” and thin wall up to 6”. There are also many chipping, chiseling, bushing, cutting and digging bits that work well with the SDS Max tools. Many of the demolition tools use the SDS-Max bits. These bits are normally sold at commercial outlets and the bits are normally sold alone. There is much more carbide on the SDS Max bits as the force of the hammering function is significantly greater than the SDS Plus sized drills. Again, the max size of the rotary hammer will be listed in the tool name. Be sure to get a larger tool than what is needed for the job. SDS Max rotary hammers can be very heavy and tough to use overhead all day long!
Long and Short
In short, SDS plus is designed for light duty applications and SDS Max was designed more for the professional and heavy duty applications. Be sure to properly size your tools for the tasks at hand. - แนวปฏิบัติและการใช้ชีวิต
I've been watching manufacturer videos for about an hour trying to figure out what the difference between two hammer drills was and all I got was stupid music and marketing crap. You've answered all of my questions and more in five minutes, thank you!
Glad we could help!
Yes, this is an excellent summary, and includes a ton of value. Thanks.
I been searching for two days. It’s a simple question and no one seems to answer effectively but YOU. Ty
When I first used an sds drill many, many years ago it was a life changing discovery, what had been taking hours now took second. Love sds.
Thanks for clarifying this for me and helping me make a more informed purchasing decision. Excellent presentation!
Thank you! Clear and concise explanation. I am no longer confused.
Thank you for the valuable information for the beginner; helps to understand the products available and the capabilities.
This was exactly what I needed to hear. I'm in the market for a rotary hammer. I've been doing more jobs requiring one and I would rather own than rent. I could never find advice applicable to my applications, always being told to "go big". SDS Plus seems to be all I need. Thank you, now I can shop for the appropriate tools.
Thanks for the SDS lesson! I learnt something today 🤓
Thanks a million for the upload. That video answered what i was wondering and more.
Thank you, in the first 3 minutes of your video you explained or answered all my questions regarding hammer drill SDS. Thanks again, great video.
Thank you for an excellent explanation of the various sizes
This was the information I was looking for. Thank you.
Very helpful and informative video...thank you!
very useful and clarifies some of the history/mystery of modern drilling in masonry. Good web video too.
Nicely explained, easy to understand and well presented, thank-you.
Thank you for the no nonsense explanation.
Clear and easy explanation. Thank you.
Last remark about 2min vs 45min, sold me. I am upgrading.
Thank you!
That was really helpful!!
Nicely done Mate. Very well explained. Great.
Super helpful, thanks!
That cleared up a lot. Thanks
Great video! You just took a lot of the mystery out of my most recent tool purchase!
As a DIY’er, I love me my tools (DeWalt is my drug of choice). I just scored on a “tool only” deal on the DCH133 ($142, otd via Woot) and bought that exact Bosch chisel and bit set ($32 otd on sale, Amazon).
My first use was removing carpet tack from concrete floors using that flat chisel and it’s ridiculously good at that. I’ve got various projects planned that will require holes in concrete and stucco; I expect I have all I’ll need for my purposes.
Thanks! I had no idea and now I am educated!
Nicely done! I knew nothing about SDS before today, I feel like my brain has grown three sizes!
You mean SDS max
Sds. Plus is good for up to 3/4”....it’s rated 1 1/8”...about 3/4 of the Max output is all you should use for bits...we use Dewalt sds plus for 5/8 and 3/4 HDU hold downs, works very fast and reliable.....anything over that we use a Hilti max...Although Flexvolt has a 1 7/8 “ coming soon at 13.3 joules...
Great videos...good info 👍🏼
Joe Framer I use a 1 1/8 bit on my sds plus drill sometimes and found that using a higher AH rated battery definitely gives it more power and speed. They only advertise more run time but reality is they allow for a lot more power also.
Yup. Have had a reliable hilti rep telling me the higher ah is capacity only, but I think most users notice more power/torque also.
great vid keep up the great content
Thank you. You done a very fine job
Great video!
Great video ........ thanks for your upload.
Very helpful...thank you!
BETTER explanation than most
great video, well explained, thank you
Great Video. You do a good job!
Awesome video thanks
Great explanation. Thanks.
Helpful video thanks👍
Awesome info thank you!!!
Very good video. I am buying a rotary hammer and your explanation was very helpful.
Good info.
That had to be hard saying SDS, SDS+ and SDS Max so fast so many times...lol
Always great videos.
Thanks
Eric
Yeah eric, I was surprised I did not mess it up!
Thank you!
Great informative & concise video. Thank you. For commercial construction use with sporadic small renovation work requiring chiseling trenches in bathroom walls for electrical and or copper lines/conduits, is it better to get a the smallest (lightest) SDS Max machine and use an SDS max to SDS plus reducing adapter instead of an SDS plus rotary hammer. My staff have broken two SDS Plus Hammers in such applications?
Between Makita and Bosh SDS Max which make and model do you recommend? Kindly advise. Thank you.
I have a Heavy Duty Bosch SDS Max Demo Hammer for Floors & Slabs and a Makita Breaker Hex Demolition Hammer.
You sir are a gentleman.
Thanks. That was helpful.
Good review
Thanks for sharing good explanation
Dang, me stupid- I thoughts that the 1"in the desciption be talkin about size of shank but nooo now I have to buy sds..... everything. Thanks for info.
Very helpful.
Yes, for anything 3/4" and under SDS Plus works pretty well, possibly even faster than SDS Max depending on your drill. SDS Plus is a lot cheaper. I decent SDS Plus drill can be had for less than $200 (DEWALT DCH133B is a good example). Decent SDS Max drills are at least $400. The SDS Plus drills are not bad and can be pretty powerful. They will work much better than a standard hammer drill
I’ve been doing commercial and industrial for almost 10+ years and I’ve seen nothing but SDS plus a majority of the time. Idk what he’s talking about.
very helpful video
Thanks Antonio.
I didn't realize I needed a special drill to be able to use the Bosch SDS PLUS CONCRETE DRILL BIT I bought.
Yes, but you can buy the Bosch Multi-Purpose bits for your regular hammer drill.
Dumb ass
Lol
For hardscape purposes, what is the best type of drill to use for wet pressure treated timbers (up to 10 1/2 “ with 5/16, 3/8, 7/16 bits)?
Id rather see footage of you in the shop than someone drilling. Maybe make the shots of people suing the tools not at long, but good video!
Can you recommend a 4 inch core bit for SDS Plus? You said in your video that you can find them but could be hard. I can't! If you have any links/suggestions please let me know. I know it will take longer to core with SDS Plus.
I wish you would have covered the threads on the shafts. There's another variable that seems to be a confusing mess. But good video , cleared up the ideology of the shanks for me.
I just inherited a nice but old Hilti Torna 765. It uses a hexagon drive shaft system. Looks like 12mm or just between 1/2" and 7/16". Is there any adapter to get from this size hex to SDS plus?
My hammer drill is not rotary. It fastens the drill bit like fastening screws so that the input portion is narrowed to fasten the drill bit. Can it be used with SDS whatever bits if it can fasten them?
Damn good review, damn good.
QUESTION....I'm in the process of digging post holes. I am hitting solid rock at approximately 20". I found a RELTON CC-36MX 1" x 36" Cold Chisel - SDS-Max. Would you recommend I use this with a SDS Max Rotary Hammer drill or find a jack hammer that accepts a SDS MAX Chisel?
what vacuum did you use at 2:18 ?
whats your recommendation if I'm looking for something that helps me chip rock when I dig into the ground to install irrigation?
Tks for sharing... how much is the SDX max bosh. Would appreciate your advice on where to get one at a better price, hard plastic case with room for all types of bits ... Tks a lot. God bless 🙏🏻👌🏻.. just subscribed
Thanks for the video. I would say its less rotary hammer and more pneumatic rotary hammer
are the shanks of all SDS drill bits are the same no matter how big or small is the bits body is? thanks
Yes, to a point.
I have a sds hammer drill can I use a sds max bit on the smaller drill, I know you can get adapter from max to sds but can you get an adapter the other way round sds to sds max.?
Unlikely that you could find an adapter. SDS Max is usually used in larger bits so for most, adapters would be pointless since the smaller sds drills could not handle those bits.
Just bought an Aoben 1-1/4 inch SDS Plus, 13Amp Rotary Hammer. There is no manual anywhere. Can you give me some advice?
2:42 how is the vacuum attachment doing anything so far away from the tip?
That is a Bosch SpeedClean bit. Check out this video on it. th-cam.com/video/5Osg2NUMANE/w-d-xo.html
WorkshopAddict yeah but its not sucking dust until he deills the hole another 18 inches deeper.
@@UpcomingJedi It's sucking dust the whole time. That's the point of these bits. Check out WorkshopAddicts video link and you'll see it in action.
I think the bit is hollow and sucks dust through from the tip? @@UpcomingJedi

i want to know, what meaning of that shortform for SDS?
Can you use the most common/typical drill bits inside of an SDS drill? I can't find this information ANYWHERE
No.
Still didn't quite catch the difference between the old SDS and the "improved" SDS+. I'm just curious as to what they changed. I have both here, and can't tell the difference.
if i am not mistaken (i worked at bosch years ago), sds had a shorter stroke than sds+
Thx for the video. Bosch bulldog sds+ corded was the drill for years, but I've switched to Ridgid 18v sds+ and it's perfect for our 3/8" drop in anchors.
The cordless Ridgid is a nice rotary hammer for those size holes!
Great video and good explanation of the bit sizing and their limits. Too many people buy because it's the 'cheapest" version but never the right size for the job. They mention core size bit, is that to say an SDS Max can core a hole up to 6 " and drill a 1 3/4" hole. What would be a hole sizing using an SDS Max Drill?
All SDS drill are rated for the max standard hole they can drill. Core sizes vary between companies.
Thanks for your videos, I am interested in the difference between Bosch Rh382 and RH 432, and which is better?
What will be you main use for the tool?
@@WorkshopAddict which would you recommend for 3/4" holes in reinforced concrete, 2" deep. 40 on a job. 20 +/- times per year ?
How's your tankless heater treating you?
Do you know of an adapter that would allow SDS-Max bits to be used on a SDS-Plus tool? I have a lot of nice chisel and point bits for my DeWalt SDS-Max demo hammer that I would like to occasionally use on my smaller SDS-Plus rotary hammer. I recall seeing adapters to use SDS-Plus bits on SDS-Max tool but not the other way around.
You want this, but plus to max? amzn.to/2N11xUi
Yep! I know it sounds silly but I only need to use the bits once in a while on the SDS-Plus tool. I even have a nice SDS-Max spade digging tool that would be nice to use. Normally, with most adapters, using bigger gizmos on a smaller tool (i.e. 1/2" sockets on 3/8" ratchet) is more common as you don't have to worry about breakage. So it's odd that they have adapters to use the small SDS-Plus bits on giant SDS-Max tools. :-)
There has to be one out there.
EOSJOE no, he sez thats not available b/c sds has less hammering power which is why they dont make the sds bits in the larger sizes to begin with. Get the bigger hammer and the adapter to use sds in sds max
That's not the issue. I already have a large DeWalt SDS-MAX 23 lb. demo hammer. I have a lot of nice chisel, point and spade tool bits. I also have a SDS-Plus tool. I would love to use my SDS-MAX chisel and spade bits without having to go out and buy a new set of SDS-Plus bits. The bits I have are the same size as their SDS-Plus counter parts. The only difference is the shaft. If there is an adapter to use smaller SDS-Plus on a big SDS-MAX tool (which to me would risk damaging the smaller bits), why isn't there an adapter to use the larger shanked SDS-MAX bits in the SDS-Plus tool? There is no risk of breaking anything when you use a large bit on a small tool. It's like using a 1/2" socket adapter on a 3/8" ratchet... no damage. But use a 3/8" adapter on a 1/2" ratchet and you can break something. :-)
Wie immer ein gutes Video. Was mir im Test aber fehlt, ist, wie unterschiedlich die beiden Bohrer im Vibrationssinn sind. Kann man das nicht testen? Für mich ist der Bosch der Gewinner. Umgekehrt (rückwärdts) drehen, leichter, rückwärtskompatibel mit den Batterien und so weiter.
Sorry wrong video :(
What’s the smallest concrete drill bits you can use with the SDS max
You can easily find them down to around 1/2", but you can use the Bosch HA1030 adapter to go to SDS plus bits if needed. Getting into smaller bits with that large of drill could cause for some breaking of bits.
Can you insert and SDS-Plus bit into an SDS Hammer Drill?
Yes
but the opposite (i.e. an sds bit in a sds+ machine) does not work. In my experience.
Installing accordion shutters. Requires about 30 tapcons each..I'm assuming that an sds plus can make the job way easier...however...is there a chance the drill can break da wall? If it is the empty cinder blocks?
Your drilling 1/4" or 3/8" holes? Most likely would not break the block but a good hammer drill like the Dewalt dcd998 or 999 might work better for you long term.
So what is SDS 3,SDS 3, SDS 5 etc.?
First time I used a rotary hammer today, before I just had a drill, not even a hammer drill, so was very surprised at the power seemed overkill 😂
What about the square Shank?
I have a Rotary Hammer Drill that has a chuck designed for SDS Plus Drill Bit. Question: A) Will i be able to use an SDS Max Drill Bit on the machine? B) Can i also insert and use a SDS drill bit on a SDS Plus Chuck Rotary Hammer Drill? Look forward to your answer.
A: No, you can not use an SDS Max bit B: You can use an SDS or SDS Plus bit
@@WorkshopAddict Thank You so much for the answer
@WorkshopAddict let's say I just want to remove old tile mortar with a removal Chisel Bit should I get SDS or SDS plus? Thanks for your video
SDS plus will fit a sds or sds plus drill. If you are asking what drill to purchase, go as large as you can and justify the cost of it for the job.
To confuse everyone but a necessary piece of information... Bosch also makes a bulldog extreme max that accepts sds plus bits up to 1-1/8 diameter. The Bosch sds max is the larger drill Styled like the Hilti and accepts the much larger max shanks and bits..... not the bulldog max series. Why they used the max terminology in both products is beyond me. Many people have bought that drill thinking their getting its larger brother performance.
Thank you for the post! I know my comment isn't related to this video, but I'm hoping you'd be willing to help me out. I often have to drill through concrete walls at least 10" thick. I use a rotary hammer drill with a 5/8 and 1/2 drill bits and I'm blowing out the other side of the wall even with the 5/8 bit. What's the best way to drill a 3/4 core hole and keep it clean without damaging the surface of the wall for mounting purposes?
Coring machine man. Hilti has a selection over the years, and you can prob find them used. And I've seen off-brand machines as well. I'd think harbor freight has'm, if ya don't want to spend 1000s for a new Hilti.
I'm thinking more about what you actually asked. Seems a coring bit is too big. If I was worried about blowing out the other side of the wall (which I do understand why you could be concerned), I think I'd try putting a search bit through, ie; 3/8" etc, then use your 3/4" on the inside where you don't want it blowing out, then outside to drill your 3/4 hole. To me it seems it won't blast concrete/stone shrapnel that way.
@@Squillaempusa. I take it that your terminology of a search bit is the same as drilling a pilot hole before using the actual bit size needed to make the permanent hole? If so, we tried using a smaller bit first, but for some reason it still blows out the other side of the wall. We're using a rotary hammer drill and I'm thinking it's the hammer that's causing the damage when it punches through the other side. That's why I was hoping that if we used a core bit that it would give us a much cleaner ending result.
Yea, search bit/pilot bit. What about using a coring bit/cup bit for rotary hammer (lined up with pilot hole) on inside wall where you're having it blow out to kinda score the wall. I'm wondering if the blow out will be contained to inside of the cup bit hole. I feel like I'm rambling. Anyway, I agree that a coring machine would do much better, but you're looking at spending some loot. Not sure what your situation is. We use one a few times a year, when going through brick or a deep concrete wall, but only when we need a 2-3" hole. Not sure about less than 1".
I do hvac, obviously I'm not a concrete guy. So take what I'm saying with a grain of salt. I have gone through concrete, brick, and stone many many times, but not terribly concerned about the blow out (as long as no one gets hit by the chunks flying), since it's usually in a basement out of sight. Plus we usually sleeve the hole and patch around it with silicone or furnace cement.
Can I able to use a normal hammer drill bit (the round one) in an SDS plus drill?
No.
Can you use sds and SDS plus bits in a SDS max drill?
no
SDS Plus has 10mm and SDS Max has 18mm shank to be specific.
So if i have sds bits are compatible to sds plus machine ?
Yes
Excellent. I spent hours with a 1/2 inch electric non SDS to make a 5/8 hole 3" deep in a granite bolder. Not fun.
when will Bosch introduce their cordless SDS MAXlike Milwaukee and Dewalt have with their 1 and 9/16th inch?
Hope soon as there are rumors of a new battery in the works.
@@WorkshopAddict Metabo HPT is the best SDS Max in its class and the AC adapter is a game changer for bigger jobs
Can you get an adapter to use sds standard bits in an sds max drill?

TH-cam is deleting the link for some reason. There are usually chuck adapters in accessory catalogs.
What's the difference between SDS & SDS Plus?
Not sure if you are still curious but there's not really one just an updated name honestly
It’s not the bit size that you choose it’s the machine size you choose. That’s how you pick a machine.
Wattage output always wins.
I would appreciate metric numbers too.
That “just under 3/8” is better known as 10mm
I just came here to see if there is a giveaway going on where i can be the top mooch. Just call me Benny.
I could be wrong, but I didn't hear the difference between SDS and SDS Plus as said in the intro.
I went through it, but Sds and Sds plus are interchangeable. Old name vs new.
