High Quality: High efficiency, high quality finish, long life, good economic returns. Easy to operate, safe and reliable, can reduce labor intensity. Design: Mechanical parts chamfering, rounding and grooving. Double chamber is cross lines, not easy to block lines, more suitable for the purpose Relatively low density material. Product Description Size:5pcs 50 -60mm Rotary Burr Set Feature: The process of various metallic and non-metallic carvings. Ideal for processing all kinds of metal (including all kinds of hardened steel) and non-metal ( such as marble, jade bone), machining hardness reach HRA85. Easy to work on the high precision of different mold cavity shapes, have good machine quality and high degree of fineness. Carbide rotary file is usually used with manual or pneumatic drive (also can be used in machine tool). The service life is long, 10 times of the durability of the high-speed steel milling cutter, 200 times the durability of small wheels. The speed of electric or pneumatic tools is generally 6000-50000 revolutions per minute. Specification:Material: Tungsten carbide steel Cutting edge diameter: 10mm Shank diameter: 6mm Overall length: 50-60mm Usage: - Cleaning trim, veining and seam welding, of forging and welding. - Finishing all kinds of metal moulds. - Turbine passage of finishing processing. - A variety of chamfering, round and groove mechanical parts . -Inner hole surface of machine parts finishing. Includes: - 5pcs Rotary Carbide Drill Bit Tool Hot Tips: 1. Carbide rotary file in the use of pneumatic or electric tools, the speed is generally 6000-40000 r / min, you need to clamp the tool. 2. The cutting direction should be moved from right to left, not like the use of the grinds as an alternate cut. Be careful not to force too much (the pressure usually does not exceed 4 kg).
