Review on 🔪 Tungsten Stainless Aluminum Cutter: Precision for All Cutting Diameters by Alex Mitra

What a great tool. I had to drill 20 holes in 1/4" diameter steel. This drill worked flawlessly. In fact, the more I used it the better it worked. Usually the pilot drill bit is terrible even with more expensive drill bits. Package. Used in a drill with cutting fluid.
