Review on TopLine Drill Bits Size Cobalt Cutting Tools for Industrial Drill Bits by Chris Pettway
Doesn't live up to expectations
This product from the industrial and scientific line was a complete letdown... As my tests showed, the size cobalt cutting tools were not nearly as effective as advertised. The drill bits were prone to breaking and did not have the longevity that should be expected from an industrial product..
Pros
- None
Cons
- Poor durability, prone to breaking
