System K 2.5 m Milling Drum (18 mm spacing)

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

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
