Description

Version:

Made of high-tensile tool steel (>1300 N/mm2). In conjunction with the convex indexable insert clamping, the system achieves very high resistance to axial and radial cutting forces and thereby significantly increases the surface quality and productivity.

Note:

Insertion ⌀ Dmin = 25 mm up to a length of 30.5 mm.
Insertion ⌀ Dmin = 27.5 mm on the entire length.
