Review on TopLine Drill Bits Size Cobalt Cutting Tools for Industrial Drill Bits by Luis Green
Carbide Drills
Letter Size Drills. Very hard alloy. Heat resistant but can be brittle, so it's used on machine tools rather than hand drills. A torque limiting clutch is also useful to prevent breakage. Wear safety goggles, of course. Good quality.
Pros
- Very Impressive
Cons
- Drill Pack
