Review on 🔩 Precision Engraving and Drilling with Titanium Carbide: 0.8-3.175mm by Dave Hock

These titanium coated carbide burs work well. Used on my split carriage mount drill press for my work, worked perfectly. I didn't insist on the number of cuts I made on each pass (since I only have these bits now, but I feel for the money I got the job done quickly, with virtually no burr on the edges and minimal Polishing effort If I've used them on steel instead of aluminum and polyester, I still think they would work, but probably more slowly.
