Offers both internal and external flushing options.

• Internal flushing uses a water tube that fits through the center of the drill and into an o-ring seal in the end of the shank to transfer flushing into the drill string.

• With external flushing, holes or a slot are required in the side of the shank adapter. These line up between seals inside the front head or water box of the rock drill when the shank is installed. Flushing medium is supplied directly to this device and is introduced into the drill string through the shank.

The shanks for hydraulic drills and some pneumatic drills have external or front head flushing. Hydraulic shanks generally have at least a 5 to 14-spline configuration, and pneumatic shanks tend to have internal or through-flushing and can generally be identified by their lugs or 4-spline configuration

Quality is very similar with famous brands, reliable performance for productivity, extended services life and lower drilling costs.
