Welded toolholder HT08

Welded toolholder HT08 for small milling machines

Reinforced toolholder system for reduced operating costs

With the HT08 toolholder system, the toolholders are permanently welded to the milling drum. They are preferred for milling drums with small cutting circle diameters. The efficient design and high strength materials increase the lifespan of the toolholder.

The advantages of HT08 welded toolholder
  • Intelligent material distribution increases the expected service life by up to 75 %.
  • Reinforced positioning cylinders enable improved repositionability.
  • The design height of the toolholder ensures the use of an automatic pick ejector at any condition of wear. It reduces the time needed for changing the picks.
  • The holder geometry enables low-wear integration of the welded seam along the border of the milling drum throughout the entire useful life.
  • Due to an adapted holder geometry and a corresponding milling pocket, an ideal welding seam can be applied onto the milling drum tube.

Reinforced toolholder system HT08

The efficient design and high strength materials increase the lifespan of the toolholder by approximately 75 %.

  • Wear margin (see measure x):
    • HT01 = 10 mm
    • HT08 = 17.5 mm

More exact possibility of re-positioning

Accurate positioning when replacing toolholders is improved by the revised geometry of the toolholder.

  • Length of the positioning cylinder (see measure z):
    • HT01 = 10 mm
    • HT08 = 17,5 mm
  • Diameter of the positioning cylinder:
    • HT01 = 7,5 mm
    • HT08 = 10 mm

Higher wall thickness of the milling drum tube

The improved geometry in the HT08 toolholder reduces the mechanical effort and enables smaller seating notches. This is particularly beneficial for the milling drum wall thickness in the area of the end ring.

Simple change of picks

HT08 is designed for quick pick changing by means of the automatic pick ejector. This reduces downtime significantly under normal field conditions.

Improved access to all toolholders on the milling drum, enhance the cutting tool replacement process.

Minimised wear of the edge ring

  • Intelligent positioning of the edge ring toolholders substantially minimises the edge ring wear on the milling drum when milling narrow radii.
