Based on our own experience with this industrial drill bit, we were thoroughly disappointed with the quality of the product. Despite being marketed as a "reduced shank twist" cutting tool, it failed to live up to expectations. The only pro was its affordable price. The cons, however, were many - poor durability, inconsistent performance, and flimsy material. Our recommendation? Look elsewhere for a high-quality cutting tool that will get the job done right.
