Review on Masterpiece: Unyielding Strength of the Multi Hardened Carbon Steel by Chris Elliott

These industrial drill bits failed to meet my expectations in terms of durability and precision. Through trial and error, I found that the bits struggle to maintain a sharp edge and often break under moderate pressure. While they are affordable, the cost in wasted time and additional replacements far outweigh the initial savings. As an Industrial and Scientific customer, I cannot recommend these bits for heavy-duty use.
