internal diameters

maximum = 50 mm)

Toolholders suitable for induction-

without a tool

In the tailstock of the lathe so that no friction occurs between the workpiece and the tip

clamping depth l2 = max

Length: 62mm

better process security and productivity

For targeted cooling and lubrication on the cutting edge/evacuation of chips

for clamping holders with coolant channels directly to the cutting edge

Carbide surfaces

With coolant channels for optimal coolant at the cutting edge
