Longdex 8mm Cylinder Head Diamond Coated Mounted Points Abrasive 3mm Shank Grinding Bit for Stone Gemstone

Feature: This product is a diamond brazing tool, it is a new generation of diamond tools. It uses 80 # diamond as raw material and is processed under high temperature and vacuum conditions. Compared with the diamond metal bond grinding head, the sharpness is about 5 times. Because metal bonding agent uses metal powder as the binding raw material to wrap diamond particles, the diamond concentration is 75% and diamond has almost no exposure rate, so the processing efficiency of such products is low. This product has a diamond content of 200% and an exposure rate of 70% to 80%, so the processing efficiency is much greater than that of diamond metal bond grinding heads. Compared with diamond plating tools, the life is about three times that of electroplating tools. Electroplating products deposit metal nickel with diamond particles by a deposition method. Such tools are composite tools, which are roughly divided into tool iron parts and effective working layers of tools. Because they do not bond well, the diamond particles fall off during use, which affects the life of the tool. Diamond brazing tools use chemical metallurgy to perfectly combine diamond particles with iron parts, so the service life of such tools is quite long. Perfect tools for DIY enthusiast or hobbyist or craft fan. Widely used for metalwork, tool making, model engineering, wood carving, jewelry making, etc. Great for sculpturing, dressing, precision grinding and internal grinding carbide in ceramic, glass, precious stone, alloy and many ther abrasive materials.
