SDS only drill bit

[david.hanna@kngroup.]

Hi folks, quick question. I have a SDS hammer Makita hammer drill, but require SDS bits, specially a 32mm diameter 500mm length drill bit for masonry drilling.

I assume an SDS+ bit is not compatible in the SDS drill. Really struggling to find SDS only drill bits, any particularly ones for my specification. Any ideas folks

That sounds confused, but....

Difference between SDS, SDS Plus and SDS Max drills?

What are the differences between SDS, SDS Plus, and SDS Max drills?The diameter of an SDS and SDS Plus shank is 10 millimeters. (The SDS Max is 18 millimeters. The SDS shank has the advantage of fitting into a simple spring-loaded chuck, so that bits are simply pushed into the chuck without...

Harry, I agree the the OP is a bit confused/confusing, but so it seems is the article to which you have linked ...

... although entitled "Difference between SDS, SDS Plus and SDS Max drills", it is essentially about SDS Plus, SDS-Top (which I'd never heard of!) and SDS Max - and therefore does not seem to directly address the OP's question!

As I understand it modern bits are backward compatible, not vice cersa.

The OP's post wasn't clear about what exactly he was confused about. He seemed to be mixing up hammer drills, with the completely different technology of SDS. Perhaps if the OP came back, and explained more clearly, then we could help him more?

All he needs to know is that SDS and SDS+ are compatible and both will work in his Makita SDS "hammer" drill. I think he'll struggle to get that size (probably getting into SDS max territory - which won't fit). Just guessing but If he needs a hole for a 32mm waste pipe it should be a bit larger and he'd probably be better off with a core drill - probably 38mm.

I think the only thing 'wrong' with the OP's wording was that he slipped in the word "hammer" - which, in terms of everyday (not technical) language is something that an SDS drill does ('hammers').

If that's the case, then he was simplhy asking whether SDS+ bits would fit into an SDS drill. My point was that, despite it's title', having read the article to which you linked, I would not have been any the wiser as to the answer to that question.

SDS and SDS+ are more or less the same thing.

There are only really two different SDS systems - SDS/+ and SDS max.

The real question would be "Can my drill cope with a 32mm 500mm long bit?"

Indeed, a corded 2kg drill is typically limited to about 28mm or less
