  • Rear access hole for easy bit removal saving time and energy
  • Optional hard facing on bit holders and sleeves for high wear applications maximizes life
  • Induction case-hardened bore extends life of the bit blocks through multiple sleeve change-outs
  • Lower profile on blocks helps alleviate potential wear and increases block life
  • Lighter sleeve extractor tool than previous version (by 1.8 kg /4.0 lbs.) provides ease of handling and maneuvering

Our genuine Joy conical cutting system:

  • Decreases the time you spend changing bits even when shanked or broken. Slightly stuck bits can be removed up to four times faster when compared to other bit holder systems.
  • Lowers costs through extended life. The induction case-hardened bore provides extended life of the bit blocks through multiple sleeve change-outs. Lower profile helps alleviate potential wear that can shorten the life of the block.
  • Increases productivity. Cutting productivity relies on more than the bit – extending to the miner’s cutterhead and traction systems. We have the experience to fully engineer and optimize the complete system.
