The first drill I used was a 1 1/8 inch and it was dull! I'm using a drill press and the drill bit won't cut. When I look at the chisel I can clearly see that the cutting edge is not sharp. I am extremely disappointed! I want to say that I drill plywood and pine boards like I make birdhouses. I will return this set. I do NOT recommend. I didn't buy the cheapest set. I thought I'd buy a decent set. I know I can get a $40 set from Home Depot.
