SDS-Plus Drill bit Set | Hammer Drill Set | 7-Piece | 4 Solid Carbide Sheaths | 5,6,6,8,8,10,12 x 160 | in a Practical Rotary Box

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.
