Drums
Wedge Lock Quick-Change System for Mining
- Interchangeable blocks for different mining applications can convert a standard spaced drum into a rock drum without the costly expense of changing drums
- No tapered or threaded parts are welded to the drum providing a longer lasting block system. Industry standard taper systems wear and lose locking capability over time
- Continuous Wrap Design - Keystone's patented block to block welding technology insures superior strength in the most extreme mining environments
- Easily change from a standard mining tool to a radial mining bits
Big Easy Quick-Change System for Mining
- Easy insert removal - unscrew holder with standard tools, no hydraulic presses or special tools required
- Interchangeable inserts provide unmatched versatility allowing for the use of multiple size shank bits for different mining applications
- Continuous Wrap Design - Keystone's patented block to block welding technology insures superior strength in the most extreme mining environments
- Keystone's patented threaded system provides more clamping force than industry standard taper systems creating a system that is stronger and lasts longer
