Review on 🔧 Fisch Pen Drill Bits 150mm: Precision and Performance in One by Tommy Willis

I don't understand the one star reviews. Did these people actually use these beats? I have and have used them a lot. They work so well that I have gradually replaced my other bits with fish spade bits and no longer buy inferior bits. They run cooler and more correctly than other bits, so there are fewer (read NO) blowout issues. They also come out clean, so you don't have to do anything special to prevent tearing on the back of the letterhead. Expensive but worth it.
