The toolholder features multiple bit removal methods and a unique friction ring design to secure it to the rotor, yielding faster replacement and reduced downtime for rotor maintenance.
- A taper and friction ring design secures the toolholders to the rotor without a retaining pin, bolt or setscrew, speeding up replacement time by up to 50% and eliminating the need for fasteners or torqueing
- 20 mm wear collar is 66% longer than System G toolholders
- An anti-rotating toolholder design ensures proper position to prevent wear on the blocks and holders
- Water can penetrate through the toolholder radial access hole to aid tooth rotation for uniform bit wear
- Toolholders are available to accommodate bits with 20 mm, 22 mm and 25 mm shank size bits for various applications
Multiple methods for easy bit removal:
- Radial access hole
- Chisel points
- Rear access through the block
- An optimized spiral angle increases speed of material flow from the outside to the center for efficient material extraction
- Blocks are specifically designed for each side of the rotor and arranged for optimized cutting effort and efficient material flow
- Kicker paddles are dimensioned and tested to ensure maximum ejection of material from the center of the cutting chamber to the conveyor
- The rotor design reduces component wear by quickly removing material from the cutting chamber, reducing drag, improving overall machine efficiency and lowering fuel consumption
- Built to withstand demanding applications and extend rotor life
- Large heat-treated surface areas on the toolholder protect the base block from undesired wear
- Components are manufactured with abrasion-resistant, high-strength alloys to withstand the toughest applications
- High-strength components stand up to the demands of high-power applications
- Toolholder and base block designs are optimized to minimize stresses and provide lasting durability
Kicker paddles are reversible for extended life
Maintaining bits and toolholders is key to achieving maximum productivity, and System K rotors are designed to simplify maintenance and get you back to work faster.
- Dual-retention toolholders eliminate the need for fasteners, reducing replacement time by up to 50%
- Bit removal can be done through multiple methods
- A variety of removal tools specifically for System K rotors help you replace bits and toolholders quickly
