Review on 🔩 Premium TopLine Cobalt Drill Bits 4 Pk: Cutting Tools for Industry Use by Devin Jirsa

August 25, 2022

The drill keeps the sharp edge straight after drilling.

I have used this twice as this product cuts good through chips on both steel and aluminum cutting edges. Much better than my cheap other drills. Now when I start making a pilot hole for a larger hole I use cobalt as much as possible.

Pros

High Performance Grade M42 Cobalt

Cons

Skimp Instruction Manual
