Products Description
Female Shank Adapters are critical connecting components in top-hammer rock drilling systems. Unlike male adapters with external threads, they feature internal (female) threads on the rod end, which helps reduce overall assembly length-perfect for tight spaces.
KATDRILLS Female Shank Adapters

Application
Female Shank Adapters transmit impact power, torque, thrust and flushing medium from the rock drill piston to the drill string, including drill rods and bits.
Their compact structure allows a longer feed stroke in limited spaces, making them ideal for underground roof bolting, tunnel drilling and narrow quarry applications.
Underground mining roof/floor bolting
Tunneling with limited headroom
Urban construction and micro-tunneling
Quarry bench and slope stabilization drilling
Features
Shank adapters are core components in drilling operations, serving as the critical connection between a drill rig's percussion mechanism and the drill string. Engineered for optimal energy transfer, they efficiently convey impact power, rotational torque and feed force, directly ensuring peak performance throughout the drilling process.
