Review on π© DEWALT Industrial Cobalt Pilot Bit DWA1240 by Payton Stovall
It is not even possible to drill a small hole in a knife blade.
I tried using three bits up to 3/16" to pierce a cheap 1/8" Tawain knife blade, and they only have a tiny mark on the blade. I was shocked and very disappointed considering this set cost $30! I used a drill press, lube and low speed and drilled until my hand got tired. Nothing. I only need two small (3/16 inch) holes in the blade of this knife and bought this kit for that purpose. I cannot recommend this set to anyone and will definitely not spend my money on it again.
- Maximum speed and life on stainless steel and other hard metals
- Not bad, but...
