Review on 🔍 Enhanced Precision: Combined Center Drills Countersinks Degree by John Bennett

You really do get what you pay for. The tip of the first broke off in the first minute when trying to drill into mild steel with lubricating oil at low speed. Luckily no hole was drilled so the tip could break inside. Uh, uh, until I flipped it over and drilled about 1/16 of an inch, and then that tip broke off - in the hole. We all know how annoying that is. One of the cheapest center drills. I think I'll pay two dollars more and buy a good name.
