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
Easy Screw Quick-Change System
- Easy tool removal with access to the tool from the back of the block
- Easy insert removal, simply unscrew the insert with standard tools, no hydraulic presses or special tools required
- Taper on taper design provides a consistent locking depth, providing a consistently smooth surface pattern
