(1)Steel tooth rock bits

Steel tooth tricone bit can increase the bit's stability and lower the tooth impact load, and enhance its wear resistance. The design of contrary turning with two lines of teeth can reduce the teeth axial load and expand life of tooth bit bearing.

Hardfacing is applied along steel teeth, including those in the heel row. Enhanced thick hardfacing is applied on sides, faces and noses of teeth for maximum protection.

In ST bits the gauge can be protected with tungsten carbide or/ and diamond compacts.
