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.
Understand the system
Bit holder
- Patented rear access hole saves time
- Added strength saves on drum repairs
- Increased weld penetration decreases drum repairs
- Lower back profile reduces block damage
- Optional hardfacing for additional life
Sleeve
- Patented undercut provides longer life
- Snap ring groove standard to maximize block life
- Black oxide provides abrasion and corrosion resistance
- Induction case hardened cavities to maximize life
- Optional hard facing for high wear applications
- Backwards compatible on J35 block series*
*Snap ring is not accessible, no extended tail version of the JS35 sleeve
Conical Pick
- Patented double bevel wedge for easier bit extraction
- Bit head diameter increased for increased sleeve life
- 360° contact between bit & sleeve for increased sleeve life
- Extended tail on internal retention for increased sleeve life
Extractor Tool
- Extractor tool can pull and press fit sleeves
- 1.8kg (4lbs.) lighter for easier handling
- Rod separates from unit for one person handling
- 2.5 times stronger for increased reliability
