BHA 10 Piece Tungsten Carbide Mini Burr Grinder Bit Set, Aluma Cut – 1/8” Shank

All these die grinder bits are aluma cut making them ideal for softer materials such as aluminum, brass, copper, carbon fiber, magnesium, zinc, plastic, etc. Furthermore, the single, wide flute of aluminum cut burrs peels away softer materials instead of grinding through thus reducing heat buildup and preventing gumming.
