Description
Version:
Made of high-tensile tool steel (> 1300 N/mm2). In conjunction with the convex insert clamping, the system achieves very high resistance to axial and radial cutting forces and thereby significantly increases the surface quality and productivity.
12.5×w (groove depth up to 37.5 mm)
Note:
Maximum ⌀ = limited workpiece ⌀ due to the tool type.
From 19.5 mm groove depth (up to groove width 3 mm) and from 24.5 mm groove depth (from groove width 4 mm) the second cutter comes into contact with the workpiece. This can lead to scoring.
If necessary, use single-cutter grooving inserts No. 273656 – 273670.
Coolant transfer only possible in conjunction with GARANT Master Eco toolholders No. 319006 − 319136.
