Overview
The System K course milling rotor with 25 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 At A Glance
Toolholder Design
- 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
- 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
Maintenance
- 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
