sds drills

[koditten]

I have a SDS hammer drill that I picked up in a garage sale 15 years ago. I plugged it in and it worked, so I gave the 10 bucks being asked for it. I believe the brand is Bosch.

I have neve used this or any other hammer drill to bore holes in concrete. I have found that I need to buy a 3/4" hammer drill bit.

My question is...are these sds bits universal? I don't want to spend 30 bucks only to find out it will not work in my old drill motor.

Basicly, school me on hammer drill motors/bits.

Many thanks in advance

No there are SDS+, SDS top, and SDS max.

I guess I won't be ordering a bit of the 'net. Into the hardware store with the drill motor I go.

Thanks

There's only one SDS Plus shank design, which must be what you are asking about. So, yes, it is universal. It's a Bosch design that is now a defacto standard.

If you have a hammer drill you don't have SDS Plus, though

SDS Plus is for a rotohammer, the SDS Plus has keyways in the side.

SDS+ is 10mm shank, SDS top is 14mm, and sds max is 18mm

The most common SDS chuck design is "SDS Plus" which will cover most drilling needs for general concrete work such as tap-cons, smaller core drilling, wedge ancor holes etc. under 1 1/2" (usually) The other common SDS chuck is SDS-Max. This is for bigger chipping and demo hammers. SDS max has replaced hex drive for the most part (outside of jack hammers) For $10, I'm sure its an SDS plus

I actually went to the rental place and rented a bit when I needed to drill a rock for a water feature. I was able to borrow the hammer drill. Just another option. If I remember it cost a ~$10 to rent a $100+ bit.

no neat sig line

I agree Larry, but having another tool is never a burden.

somebody said it is for hex shank.....

if so...throw it away and buy a SDS Plus drill preferably from the worlds largest rotary hammer drill manufacturer: Bosch

 

[KnurledNut]

Your rotohammer takes a special 7/16 hex drive bit. ICS still sells them.

I would have to agree. Go with SDS+ rotary hammer. Just rent it if it is just for one project.

Right, but the Skil 717 used a different style of hex shank bit, not the far more common 7/16" and 9/16" hex shanks used by other models of Skil roto-hammers, and most Black & Decker, Milwaukee and Rockwell rotary hammers of that era.

 

[koditten]

Anyone want to buy a Skil 717?

Looks like I got a spare power cord for 10 bucks.

Thanks for all the effort in schooling me.

Later

FYI, my Dewalt D style hammer drill accepts SDS and SDS+. You can also buy addaptors to accept the other sysles as well.

SDS and SDS+ are all interchangeable - see link in post 14.

The op's answer has been answer, he did not get a sds rotary hammer but a skill hex shank.

Don't give up so fast. As KnurledNut said, ICS still sells bits for the Skil 717:

(Second listing on the page for Skil 717, not the B&D 717 at the top.)

Assuming you really want to have your own rotohammer instead of just renting when needed, or spending $300 on a new one and the price of bits on top of that.

The old Skil rotohammers were excellent heavy-duty tools and well-respected. The only reason they're not still making them is because when Bosch and Skil merged in 1992 (before complete ownership by Bosch in 1996), the competing industrial-quality products in the Skil line were discontinued.
