Description

Mill tooth tricone bits  are made of high-strength alloy materials from tricone cone bit manufacturers. It not only improves the impact resistance of teeth, but also comprehensively improves the shearing effect and sliding distance of the drill. At present, this accessory can be well used in modern drilling engineering, which can not only effectively reduce the possibility of broken teeth, but also optimize the arrangement of the number of teeth and the number of teeth, and make full use of the function of the tooth milling bit.

In the manufacturing process of the bit cone, it uses an inner hole welded antifriction alloy, which can improve the bite ability of the bearing to a certain extent, and also installed to limit the pressure difference and prevent mud from entering the lubrication system Rubber sealing device. The capacity and service life of the seal lubrication system of the drill bit can be significantly improved.

our main mill tooth tricone bit products are: milled steel teeth tricone bit, mill tooth tricone bit iadc, Mill Tooth Tricone Bit IADC etc.
