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.
From 19.5 mm onwards (up to groove width 3 mm) or from 24.5 mm onwards (from groove width 4 mm onwards), the second cutter comes into contact with the workpiece. This can lead to scoring. Use single-cutter grooving insert no. 273656 – 273670 if necessary.
Coolant transfer only in conjunction with GARANT eco-system toolholders No. 317900 − 319886.
