Drill Bit

详情

Button Bits The skirt body using the material of *5CrNiMnV(Chromium, Nickel, Manganese, Vanadium)alloy steel, taking the heat-inlay fasten s technology, when the drill bit drilling, the drill bit temperature can reach to ******0 degrees, but our bit skirt body is still have a good force to hold the s, and it’s very rare to appear the s take off the body and body failure. We use the Boart longYear and the Chinese famous brand’s cemented carbide, it’s wearing resistance and bending resistance both are very good. DTH Bits The skirt body using **0 alloy steel, and go though the ***0 tons extruder have the heat extrusion to ensure the skirt body have the strength to resist impact strength. We take the Chinese famous brand’s cemented carbide, it’s wearing resistance and bending resistance both are very good.
