Shanks Adapter for drilling has a great influence on rock drill and drill life so smooth flat end face shanks length should be appropriate, cross section and the vertical axis, and with the rock drill drill sleeve anastomosis is not more than 0.5 mm (gap) bit tail 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 is advisable.

Shank Adapter Specification for Rock Drill

Advantage of shank adapter:

Shank adapters (striking bars) ensure a quality drill string interface to the most exacting industry tolerances. Built to seamlessly interface with hydraulic and pneumatic drifters and top hammers, our shank adapters come in a full range of industry-standard thread configurations. Our precision grinding process ensures straightness, and our tools are fully carburized with an advanced heat treatment.

Male shank adapters are ideal for drifting, tunneling & extension applications where high bending stresses are present, and female shank adapters are used when the drilling space is limited and the total feed length is important.

Shank adapters are used for transmitting power from the rock drill to the drill stems. Generally there are male threaded shank adapters and famal threaded shank adapters. Male shank adapters are more popular than famale shank adapter. Male shank adapter are generally suited for drifting , tunneling and extension applications where high stresses are present. Females shank adapters are used when the drilling space is limited.
