Standard SDS Drill Bit into an SDS Plus Chuck?

[maverickone]

HI wonder if someone can tell me if a standard sds bit will fit into an sds Plus chuck?

I know the flutes are longer and I believe there are more of them on a plus bit but will a standard bit fit the plus chuck?

Thanks

SDS (if you can actually find one) and SDS+ are compatible.

Not to be confused with SDS Max, which is entirely different.

Indeed.

Maverick, if you are sure that's what you have, please upload some decent pictures of the shank. There is almost nothing out there in Google-land and lots of conflicting information on the differences. No-one seems to even agree what SDS stands for!! Some definitive proof would be nice.

The best I've been able to find is this shot of some original Hilti SDS bits. (I think... unless it was Hilti's own preliminary version before they collaborated with Bosch on the design).

Does this match your recollection flameport? It had the round ended 'closed grooves' but not the 'open grooves'.

Thanks guys I was confused. It was the SDS Plus and SDS Max bits i'd seen.
About to buy my first SDS Rotary Drill after my 20yr old trusty Black & Decker failed to drill a decent hole for a sheild anchor bolt in a house brick.

Think i've just about got my head around it all now.

From Wikipedia

"The name SDS comes from the German steck, dreh, sitzt (insert, twist, fits). German-speaking countries may use Spannen durch System (Clamping System), though Bosch uses Special Direct System for international purposes."

That's the ones

Thanks, that's what I thought the difference was. While googling, I even found a few Americans saying the diameter of the original SDS was different. Arguing about them being 400 thou' instead of 10mm!! SDS is German, of course they're in millimetres!!

I also notice in the photo, the base appears to have a 'dog point', like some faceplate/grub screws, rather than the 45° chamfered edge base I've only ever seen.
