The price was right for what I received...not the top of the line but good enough

First bit I used didn't want to cut at all but the two bits I used after that worked well.

Good stuff.

The bits work very well. The 5/8th bit walked a little when starting on hard steel, but I'm a novice, and also let it get too hot by initially using high RPM's. There was no slippage in the drill.
