System K 1.3 m Milling Drum (15 mm spacing)

System K 1.3 m Milling Drum (15 mm spacing)

Cat® System K milling drums are designed with advanced features for surface removal or complete removal of road surfaces.

Rotors

DESCRIPTION

The System K standard milling rotor with 15 mm bit spacing is ideal for surface removal or complete removal of road surfaces at depths up to 330 mm (13 in). A durable, high-performance design with efficient material flow and an excellent cutting pattern maximizes milling production.

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

Multiple methods for easy bit removal:

  • Radial access hole
  • Chisel points
  • Rear access through the block

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

  • 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

Kicker paddles are reversible for extended life
