Features

  • Toolholder Design

    Toolholder Design

    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
  • Easy Bit Removal

    Easy Bit Removal

    Multiple methods for easy bit removal:

    • Radial access hole
    • Chisel points
    • Rear access through the block
  • Efficient Material Flow

    Efficient Material Flow

    • 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
  • Durable Design

    Durable Design

    • 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
  • Reversible Kicker Paddles

    Reversible Kicker Paddles

    Kicker paddles are reversible for extended life

  • Maintenance

    Maintenance

    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
