- Drifter
What the SPLINED SHANK does
The shank adapter is the drifter's connection to the drill string. Its back end takes the blow from the percussion piston; its splines take rotation from the chuck; its threaded end carries the rod. Every joule the machine produces passes through this single component, and it is designed to be consumed.
Signs it needs replacing
- Mushroomed, cracked or bruised strike face at the back end
- Worn or twisted splines
- Damaged or galled thread at the rod end
- Blocked or eroded flushing bore
Before you fit it
Retire a shank adapter on strike-face condition, not on hours. A shank allowed to run past mushrooming transmits the damage straight into the percussion piston and the front bushing, which turns a routine wear-part replacement into a drifter rebuild.
General guidance for this class of component. Always work to the torque figures, clearances and service intervals in your machine's own manual.
