Carbide Carving Bits Rotary Burrs Set of 10pcs, Tungsten Steel File, 3mm Straight Shank and 6mm Double Cut Head, for Wood Carving Engraving and Metal Polishing
TUNGSTEN STEEL – The burrs are made of top quality tungsten steel (solid carbide). The hardness is more than HRA 85, which means they can last much longer than high speed steel burrs or grinding wheel.
3MM SHANK – The 3mm straight shank can be held by any rotary tool with three-jaw chuck for accurate centering. A good choice of DIY carving, engraving, and polishing.
DOUBT CUT DESIGN – The groove lines of the head are crossed. The cross pattern is faster to remove chips than a single cut can be, and it is not easy to be blocked when grinding and engraving. That's why it's more suitable for an object whose density is relatively low, such as wooden, plastic, and aluminum.
