8pcs 6mm Shank Tungsten Carbide File Multi-Tool Wood Carved Grinding Milling Cutter Milling Cutter Attachment With Storage BagFeature:(1) It can process a variety of 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 a chuck in most of the work, and there is no dust pollution. (3) the production efficiency is high, which is tens of times higher than using a file, and nearly ten times higher than that of a small grinding wheel with a chuck. (4) The product has good processing quality and high finish, and can process precision mold cavities of various shapes. (5) long service life, ten times higher than the life of high-speed steel tools, and more than 200 times higher than that of small grinding wheels. (6) It is simple and convenient to use, safe and reliable, can reduce labor intensity and improve the working environment. (7) the economy is greatly improved, and the comprehensive processing cost can be reduced by dozens of times. Tungsten steel grinding head: mainly used on pneumatic or electric drive tools, the speed is usually 6000-50000 r/min, the tool should be clamped vertically when used, the cutting method should be upward milling, avoid reciprocating cutting, and should prevent chip dispersion. Specification: Material: Tungsten Carbide Shank Diameter: 6mm Shank Length: About 40mm/1.57in Number of Rotary Files: 8 Pieces Hardness: Up to HRC70Box Size: 140x105x2 5mm/5.51x4.13x0.98in Main Application: Tungsten Steel grinding head has a wide range of applications, and is used in machinery, aerospace, automobiles, shipbuilding, chemical industry, craft sculptures and other industrial sectors, And the effect is remarkable. (1) finishing various cavities of metal mold, such as processing shoe molds and so on. (2) Various metal and non-metal-metal handicraft sculpture, such as mold carving, trimming handicraft for gifts. (3) Clean the flash, burrs and welding casting, forging and welding parts, such as machinery of foundry, shipyard, automobile factory, etc. (4) chamfering, rounding and grooving of various mechanical parts, pipe cleaning and surface inner hole finishing of mechanical parts, such as machinery factories, repair workshops, etc. (5) repairing the rotor guide part, such as the motor for the car.
