SDS v SDS Plus

[AndyPRK]

I have some SDS drill bits and need to purchase a drill to drive them.

A lot of the ones I am looking at are SDS Plus.
Are they backwards compatable?

Will an SDS Plus drill fit an SDS bit?

Thanks

Would be interested to know the difference

Most 'SDS' bits are actually SDS+ bits. SDS is a smaller fitting than SDS+, and SDS Max is bigger than SDS+. + has nothing to do with rotary stop (they may or may not have it). I've never actually seen an SDS fitting, only SDS+ and bigger.

I think my bits are 10mm - 26mm

What size is the shank?

Thanks for the link. Very useful.

Mine are 10mm dia, with 4 grooves, so SDS plus
