This is the SAME SET, same brand name, WARRIOR, not DRILL MASTER as Harbor Freight sells for about $10 more. Price. Works well for a while but doesn't hold an edge and doesn't cope with hard things like nails etc. Mild steel can be changed, but once the tip of the screw is tightened. If I wanted to throw away the Beats, I would buy them cheaper at HF. I was hoping they were a bit higher quality. No such luck
