Quick-change toolholder system HT22 for cold milling

The quick-change toolholder system HT22 PLUS is primarily distinguished by its higher wear resistance. The system's exceptionally long service life leads to noticeably longer pick and toolholder replacement intervals during operations on construction sites. It is also characterized by a prismatic layout of its mounting surface.

For the user, this results in longer life of the pick and toolholder system. The resulting benefits – fewer pick changes, fewer and shorter machine down times, longer maintenance intervals and higher machine utilization rates – enable cost-efficient stabilization of even the most difficult soils and efficient milling and recycling of severely damaged road pavement layers.

This makes milling drums equipped with the HT22 PLUS quick-change toolholder system the ideal choice for particularly challenging milling tasks. In addition, the heavy-duty construction of the milling drums enables the top parts of the quick-change toolholders to be exchanged quickly and easily whenever necessary, also on the construction site.

The new top part of the quick-change toolholder HT22 PLUS features an innovative, embossed centering recess in the pick contact surface. In combination with the new Generation X² round-shank picks, this reduces toolholder wear by up to 25%. The rotation behavior of the round-shank picks has also been optimized. The most significant benefits of the new top part are the higher quality of the milled surface and longer replacement intervals.

One of the most important factors in every application is minimizing the time required for servicing and replacing pick holders. This is why the HT22 quick-change toolholder system, with its minimal maintenance requirements, perfectly complements PCD cutting tools compared to all other pick holder systems available. The top parts of the HT22 need to be replaced at the same interval as the PCD cutting tools. This considerably reduces maintenance requirements, such as retightening the retaining bolt.
