Review on Enhance Your Masonry Work with Century Drill Tool 86956 – A Reliable Powerhouse by William Bell

Bought to pre-drill concrete screws for fastening plywood to concrete slabs. Not a particularly difficult task, but bits (I bought two) naturally dulled after a few , that's a terrible achievement. Looking back I can honestly say I can't remember exactly what RPM the drill was at - maybe the RPM was too high. But as for me, next time I'll try a different piece.
