Shank Adapter

Shank is mainly used for mining operations, choose high quality alloy steel as raw material, after carburizing process as a whole.using special cnc machine tool processing equipment and processing process to ensure the tail details, inner hole and side hole machining quality.bit tail after the uniform heat treatment, the use of precision instrument science and straightening, guarantee the straight shank and manic resistance.
The role of the shank is directly under the impact of the drill power and torque.
Shank specifications and hardness of drilling speed, has a great influence on rock drill and drill life.so the shank length should be appropriate and end face level off, smooth, cross section and the vertical axis, and with the rock drill drill sleeve anastomosis is not more than 0.5 mm (gap).shanks to appropriate hardness, too soft bit tail short service life, high piston vulnerable, general shank should be slightly lower than the piston hardness hardness, quenching hardness hrc = 38 ~ 45
