SDS Plus Drill Bit Set | Hammer Drill Bits for Concrete with 4 Cutting Edges | Sizes 5, 6, 6, 8, 8, 10, 12 | Concrete Drill Bits | (SDS Plus, 7-Piece Set)

better than many other SDS bits I've used in the past, gets through faster than most even in light duty SDS drills, my only gripe is this set needs a 4mm bit for pilot hole use rather than 2 X 5mm and 2 X 6mm, otherwise a very good set

All good they work well

Handy

Effective at grinding out decking rusted screw-heads where screw-removal tools and impact driver failed.

I asked the community before purchasing these and they did my right. Eats through concrete.
