2025 Caterpillar Rotors System K 2.2 m Milling Drum (18 mm spacing)

2025 Caterpillar Rotors System K 2.2 m Milling Drum (18 mm spacing)

The System K course milling rotor with 18 mm bit spacing is designed for surface removal or complete removal of road surfaces with a rougher finish 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.

Features may include:

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

Multiple methods for easy bit removal:

• Radial access hole

• Chisel points

• 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

• 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

• 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
