5pcs Kit 6mm Shank Tungsten Carbide Burrs 8mm Head Double Cut Tungsten Carbide Rotary Burr Set for Metal Wood Engraving Ceramic Polishing,T-Audace High QualityMade of high strength treated tungsten carbide, high abrasion resistance and good toughness. Processing hardness reaches up to HRC70, packed with plastic case for safe storage and good protection DesignMechanical parts chamfering, rounding and grooving.Double slot is cross lines , not easy to block lines, more suitable for the object of relatively low density material High efficiencyThe rotary cutter set has high production efficiency, with 10 times higher than the manual file tool, and almost 10 times higher than the small grinding wheel with the handle. In most cases, it can replace a small grinding wheel without dust pollution Wide UseSuitable for metal polishing, wood carving, jewelry, hobbies, crafts , craft style, home repair, etc. Product Name: Carbide Rotary File Specifications: 6*8mm Texture: Double grain Packing specification: 5 Pieces Main Application: The tungsten steel grinding head is widely used in machinery, aviation, automobile, shipbuilding, chemical industry, carving craft and other industries, with remarkable effect. (1) Finishing various metal mold cavities, such as shoe mold processing, etc. (2) Various carvings metal and non-metal crafts, such as mold carving, craft gift cutting. (3) Clean the flash, burrs and welding bead of casting, forging and welding parts. welding, such as machinery foundries, shipyards, automobile factories, etc. (4) Chamfering, rounding and groove processing of various mechanical parts, pipe cleaning and interior surface finishing hole of mechanical parts, such as machine factories, repair shops, etc. (5) Repair of impeller parts, such as automobile engine factories. The tungsten steel grinding head mainly has the following characteristics: (1) It can process various metals (including hardened steel) and non-metals (such as marble, jade , bone), and the processing hardness can reach up to HRC70. (2) It can replace the small grinding wheel with handle in most jobs, and there is no dust pollution. (3) High production efficiency, which is tens of times higher than the processing efficiency with a file and nearly ten times higher than the processing efficiency with a small grinding wheel with a handle. (4) The product has good processing quality and high workmanship, and can process high-precision mold cavities of various shapes. (5) Long service life, ten times more durable than high speed steel tools and more than 200 times more durable than small grinding wheels. (6) Simple and convenient to use, safe and reliable, can reduce labor intensity and improve the working environment. (7) The economic benefit is greatly improved, and the whole processing cost can be reduced tens of times. Grinding head made of stainless steel tungsten: mainly used on air or electric driven tools, the speed is generally 6000-50000 rpm, when using the tool is tight and tight, the cutting method is preferably cut towards the top, avoid reciprocating cutting and should prevent chipping. fly away.
