Specification: 2.35mmX6.0mm (ShankXBlade) Working part: diameter=6mm,made of YG8(ISO k20-k30)Tungsten Carbide with steel shanks, density 14.6-14.9 g/cm, power of bending resistant >2000 N/mm3, Hardness >89 HRA Shank: Diameter=2.35mm, made of #45 steel, Oil for antirust 100% brand new and high quality It is suitalbe to wear resistance parts, drawbench mould, construction drill. It is shock-proof and also suitable to cast the non-ferrous mental, alloy and process the nonmental material slowly and roughly. Also can grind marble, jade and other non-metallic materials Petiolate can basically replace the small wheel, there is no dust pollution Grinding efficiency is increased to 10 times better than manual files and petiolate wheels Processing is high quality and smoothness and can be all sorts of high-precision shape Safe, reliable and convenient to use Long life: over 200 times than the wheel HRC processing hardness: 70
