Review on 💪 Durable Carbide Cutter: Heavy Stainless Steel - Achieve Precise Cuts with Ease by Robert Rick

I've drilled a few dozen holes in the 316 stainless steel tubing and it's still as sharp as when I started. I use it on a drill press and my work is clamped so it can't move. I run it at 300rpm with constant pressure and no coolant and it just chews through. I don't do many reviews unless something is really outstanding or really terrible. These are definitely the stars. Can't wait to get additional sizes for other projects now that I know how well they work.
