The milling and mixing rotor in the WR 2400 is suitable both for soil stabilization and cold recycling.

The modern milling and mixing rotors of Wirtgen cold recyclers and soil stabilizers are equipped with the HT11 quick-change toolholder system with a larger shaft diameter of 22 mm.

The toolholders of this system consist of a bottom part that is rigidly welded onto the rotor's body and an upper part that is fastened to the bottom part by a retaining bolt. The upper parts accommodate cutting tools that rotate freely in the tool shaft during the stabilizing or recycling operation.

The hallmarks of this system include:

• Optimum cutting tool rotation
• Fast and simple tool extraction
• Extremely low wear and tear
• Wear markers for monitoring the state of wear of the upper parts
• Large retaining bolts to ensure a perfect fit of the tools in the toolholders

Please consult Parts and More for additional information on this and any other Wirtgen toolholder systems.

Using cutting tools of superior quality, which are specially adapted to both the operation and the machine, the WR 2400 achieves top production rates at low tool wear and tear.

The tips of point-attack tools are subject to tremendous loads, and are therefore made from particularly wear-resistant carbide metal.

The steel body enclosing the tool tip is divided into two zones: The tool head is particularly hard and highly wear-resistant, while the shaft is tougher and more break-resistant. The different degrees of hardness in the tool head and shaft guarantee optimum properties during the entire tool life.

Different cutting tool types are available for Wirtgen soil stabilizers and cold recyclers. Please consult Parts and More for the full range of cutting tools available for road milling machines, cold recyclers, soil stabilizers and surface miners.
