Rotors Caterpillar System K 2.2 m Milling Drum (18 mm spacing)

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

Your Cat dealer offers convenient parts availability and service options, with an industry-leading supply chain and worldwide distribution to keep your rotor cutting smoothly and efficiently.
