Mature toolholder systems for the soil stabilizer WS 220

HT11

Quick-change toolholder systems consist of a bottom part that is rigidly welded onto the drum body and an upper part fastened to the bottom part by a retaining bolt. The upper parts accommodate cutting tools that rotate freely in the tool shaft during the milling operation.

Hallmarks of the HT11 quick-change toolholder system include:

• Optimum cutting tool rotation
• Additional cooling of the tools due to the toolholder shape
• 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 our website Parts and More for additional information on these and any other Wirtgen toolholder systems.

Wirtgen point-attack cutting tools - Top performance in each single tool

Using cutting tools of superior quality, which are specially adapted to both the operation and the machine, top production rates at low tool wear and tear can be achieved. 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. Their special shape, materials used and different degrees of hardness enable the cutting tools to absorb the shear stresses and impact loads acting on them.

A wear plate additionally protects the upper part of the toolholder from premature wear and tear. The clamping sleeve ensures optimum tool rotation, precise positioning, and a firm hold of the tool in the toolholder.
