Review on Double Carbide 0 118 Rotary Cutting by Matt Tbone

I didn't have the opportunity to use these bits often. Judging by the looks and the little use I've had, they seem to be of good quality. So far I would recommend. UPDATE - after almost five months of using these bits, they are a must have. I've used them on just about everything: mild steel, hardened steel, cast iron, aluminum, wood, PVC, ABS, glass, concrete, ceramic tile, marble, lexan, and brass. They have withstood heavy use very well. They are high quality and durable. worth your money. They should last the average Joe for life. I will also buy a smaller diameter set. Highly recommended.
