SDS-Plus is a hammer-bit shank system for compatible rotary hammers and lighter concrete drilling applications.

Spline-shank hammer bits fit compatible older-generation hammers and remain useful for demolition and concrete work.

SDS-Max is a larger hammer-bit shank system intended for compatible heavier rotary hammers.

Anchor holes require the correct bit system, diameter, depth and dust-control method.

Locking problems are often caused by contamination, worn grooves, the wrong shank or a damaged chuck.

Slow drilling can come from a worn tip, wrong hammer mode, excessive dust or a bit that does not suit the material.
