SG antifriction bearing indented chisel structure With high-saturation butadiene acrylonitrile rubber sealing and special treatment of seal part surface, the bit has better sealing which can bear 260centigrade. Low-wear grease improve the lubricity and service life of bit sealing. Put the cylinder into the cone indentation,widening the shaft diameter, and meeting the demand of high-speed drilling. Milled tooth bit adopts optimization design of cutting teeth, with teeth surface strengthened by special wear-resistant alloy. Stronger wear-resistance and better performance price ratio. Repeated optimizated cutting structure of insert bit and hard alloy teeth with wear-resistance and i***ct-resistance make high efficiency. Wear resistant alloy is welded on the top of the conehead, strengthening its protecting function.Has good thermostability and can work in mal-condition. |
