SHANK ADAPTOR, COUPLING SLEEVES, BUTTON BITS

Shank Adapters
The shank adapters are manufactured from specially selected
alloy steels followed by heat treatment through carburizing
which withstands the high impact power of drilling. This product
line has been recently introduced by Mindrill and the quality is
highly appreciated by the end users. Presently we maintain stock
of few selected fast moving categories but we can undertake
manufacturing of the same as per customer’s requirement, if
quantity permits.
Coupling Sleeves
Coupling Sleeves, other name is coupling, when using rock
drills with male shank adapters and a conventional drifter rod, a
coupling is required to join the adapter to the rod ensuring the
ends touch for efficient energy transmission.
