KNOW-HOW

Carbide metal bites its way through road and rock.

Wirtgen cutting technology

When operating a cold milling machine, cold recycler or surface miner, the carbide tips of the point-attack cutting tools used are subject to particularly high loads. The cutting tools rotate in toolholders, which are in turn welded onto the milling drum.

At the heart of every milling application

It is mainly the tips of the cutting tools used for milling that come into contact with the highly abrasive material to be milled. That is why they are made from highly wear-resistant carbide metal. Tool tips are available in different shapes and sizes, suitable for milling different types of material. In addition to that, the steel body of the point-attack cutting tools shows different degrees of hardness in the tool head and tool shaft, optimizing their breaking strength and resistance to wear and tear.

The right point-attack tool for any application

Their special shape, the materials used and different degrees of hardness in the steel body enable the cutting tools to absorb the shear stresses and impact loads acting on them during the milling operation. Different types of cutting tools are specially tailored for use in different applications, like cutting hard rock, milling asphalt or concrete, stabilizing soil or recycling road pavements.

Fast replacement on site

Wirtgen toolholder systems permit easy replacement of cutting tools on site, offering a high degree of economic efficiency. Most Wirtgen milling drums are additionally equipped with quick-change toolholder systems, which enable worn upper toolholder parts to be replaced on site quickly and easily.
