A: Parallelogram shape possessing an 85-degree nose angle.
P: Positive flank relief showing an 11-degree clearance angle.
K: Precision milling tolerance class for highly accurate indexable pocket positioning.
T: Single-sided insert face containing a countersunk screw hole and chipbreaker geometry.
17: Substantial cutting edge length of 17.5 mm for managing deep axial milling depths.
04/05: Heavy-walled core providing a nominal insert thickness of 5.56 mm to absorb massive shear forces.
50: Extra-thick corner nose radius of 5.0 mm engineered for complex step-profiling and maximum edge protection.
TT8020: TaeguTec’s ultra-tough PVD-coated grade. Formulated with a micro-layered TiCN matrix, it acts as one of the brand's most impact-resistant grades. It is optimized for heavy interrupted cuts, scale-surfaces, or unstable setups across steels, stainless steels, and heat-resistant superalloys.
