Shank Adaptor Striking Bar Shank Adapter For Rock Drill Drifter
Tunneling
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.

Different shank adapters are available, like Atlas Copco, Tamrock, Ingersoll Rand,etc. Also
for the same drill machine, due to different applications, the
shank adapters can be different length and different threads.
Atlas Copco (COP1238, COP1838, COP1032 and etc)
Furukawa (HD715, HD612, HD609, PD200 and etc)
Ingersoll-Rand (VL140, VL671, YH80A and etc)
Tamrock(HLX5, HL600, HL500, HL300, HL 700, HL850, HL1000, HL1500
and etc).
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.
Rock drill brand: Atlas Copco, Tamrock, Ingersoll Rand, Boart Longyear, Furukawa,
Montabert, Soonsan, Everdigm, others.
Thread size: R25, R28, SSR28, R32, SSR32, R35, SSR35, R38, T38, T45, T51,
