Review on 🔪 COMOWARE Silver Industrial Cutting Tools with Reduced Shank for Efficient Storage by Terrence Castillo

I bought a 29 piece set that works great! But I needed a 5/8" bit to add to my set. Firstly, I took a chance as the set worked so well. This 5/8" drill bit bent on the shank the first time it was used in a power drill, rendering it unusable. It started to wobble when the first hole was drilled in a 1/4 inch mild steel plate. Using cutting fluid, I started by drilling a 1/8" pilot hole and worked my way down to 1/2" before using 5/8". .
