Review on 🔩 DEWALT Industrial Cobalt Pilot Bit DWA1240 by Payton Stovall

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.
