Cuts well and lasts a long time. I learned firsthand to check screw tightness before each use. My first bit appeared to have the screw loose and wouldn't fall out until the threads were loose, rendering the bit useless after threading about 70 pounds of pressure treated 1x4. The racquet was quickly replaced by the seller free of charge. When I received the second bit, I found the screw wasn't carelessly loose, but not as tight as I thought it would be. With a little more tightening I was able to finish the job (about 70 pounds more) and still cut well with no problems.
