Rotary Carbide Burr Set 1/8" Shank, 1/4" Head Length Tungsten Steel for Woodworking Drilling Metal Carving Engraving Polishing

3*6mm Metal Drawing Tungsten Carbide Milling Cutter Rotary Tool Burr CNC Engraving Abrasive Tools Metalworking Milling Polishing Double cut burr (Cross Strips) have more cutting edges and could remove material much faster. It is more suitable for relatively low density materials such as wood, plastic, aluminum, soft steel and all non-metal materials.Single cut (Paralleled Strips ) burr provides large, wide flutes evacuate the large chips easily and also prevent iron-chip accumulate and over-heat cause cutter head damage. It is more suitable for relatively high density materials such as iron, alloy steel, stainless steel etc. Features:                                                                                                           Processing all kinds of metal(including all sorts of hardened steel) and non-metal (such as marble, jade, bone). Machining hardness reach ≥HRA85. For the most work it can be replaced with small grinding wheel,and no dust pollution. High efficienc
