🔍 Enhanced Precision: Combined Center Drills Countersinks Degree Review

Thanks to my knowledge gained in practice, these industrial drill bits have become a staple in my toolbox. Their versatility is unmatched - able to function as both center drills and countersinks, and their compact size makes them easy to store. The angled design ensures precision and clean cuts every time. However, they may not be suitable for heavier industrial tasks. Overall, a great addition to any cutting tool collection.

I laughed at the reviews saying they were tiny because, yes, they are #0. But the tips are almost needle-like and break very easily. May be useful on wood or plastic, but unsuitable on aluminium.

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.
