Review on 🔧 High-Quality Carbide Burr Set by JESTUOUS - 1/4 Inch Shank, Double Cut Solid Tungsten Cutting Burrs Rotary Files Bits for Die Grinder, Metal Grinding, Woodworking, Drilling, and Carving - Includes 10pcs by Kevin Flores

These things are real! I am restoring a Challenger 71 and have used them for grinding welds in tight corners and they work like a charm! Sharpened, sharpened, never dulled. :) DON'T BE JACK*SS! Wear eye protection! A full face mask is even better. These things are made of very strong steel, and at high speeds (Grinder) a piece of it will fly off and hit you everywhere, doing serious damage! Cutting head and shank are made of one piece and are very durable. You don't have to worry about your head falling off them. Excellent value for money! When I finally get them blunt I will buy another set.
