ISO Code Structural Breakdown
A: Parallelogram-shaped profile presenting an 85-degree nose angle.
D: Positive flank relief with a 15-degree clearance angle to eliminate heel-rubbing on the workpiece.
K: Precision milling tolerance class to guarantee uniform cutting heights across replacement indexes.
T: Single-sided insert face constructed with a countersunk screw hole and chipbreaker.
18: Nominal cutting edge length code of 18 mm for deep axial milling passes.
06: Structural insert thickness of 6.35 mm to withstand extreme torsional cutting forces.
08: Corner nose radius of 0.8 mm to strengthen the tooltip edge and deliver standard surface finishes.
IC328: Iscar's classic multi-layered PVD-coated carbide grade. Formulated with a tough substrate protected by a TiCN coating matrix, it offers superb resistance to thermal shocking and impact. It is optimized for heavy, interrupted cuts in carbon steels, alloy steels, and stainless steels.
