Auniwaig Tungsten Carbide Rotary Burr 3mm / 1/8" Shank, 5mm Head Size Single Cut Spherical Carving Burr Bits, for Woodworking, Drilling, Metal Carving, Engraving, Polishing 2pcs

Auniwaig Rotary FilesPackage Content:2pcs x Rotary FilesSpecification:Shank diameter: 3mm / 0.12inchCutting edge diameter:5mm / 0.2inchBit Type: SphericalMaterial: Tungsten Steel AlloyDescription:1.Can be used to finely process metal die cavity and mechanical chamfering, rounding, grooves, and clean up burrs of castings, flashings of forgings, welds of weldments.2.Suitable for woodworkers and enthusiasts who clean up welds or works with metal frequently. Easy to grasp and use. Unique tooth angle prevents chipping.3.Tungsten Carbide burrs can be processed cast iron, cast steel, carbon steel, alloy steel, stainless steel, copper, aluminum and other metals, and marble, jade, bone and other non-metallic. Processing hardness up to HRC58-60.4.Mainly used for grinding channel impeller, cleaning tubes, finishing mechanical internal surface, enlarging holes, processing and engraving metal non-metal materials.5.It can replace the petiole small wheel without dust pollution, and process out a various of high-precision mold cavity. High production efficiency, the processing efficiency is several times higher than file, nearly 10 times higher than small wheel stalk.Note:1.Clamped down tightly and be sure the working direction is always counterclockwise during use.2.Mainly used on pneumatic or electric tools, the requirement rotating speed is: 4000-50000 rpm.3.Prevent chips flying apart when working and better wear goggles. Keep your eyes and belongings away from the working bits.
