Part of the T-A Series, this insert measures 35\/64 inches in diameter with a 132-degree point angle and a 0.125-inch thickness. It is finished with a TiN (Titanium Nitride) PVD coating to extend tool life and reduce friction at the cutting edge. The manufacturer grade is C2 (K20), indicating a fine-grain carbide formulation suited to abrasive and interrupted cutting conditions. This insert is installed and replaced by machinists and toolroom technicians working on CNC and manual drilling operations.\u003c\/p\u003e\u003cp\u003eThis insert is intended for use in T-A Series spade drill holders with a Seat Size 0 designation. It is engineered for drilling stainless steel, cast iron, non-ferrous metals, and super-alloys including titanium. These material categories correspond to ISO workpiece material codes M, K, N, and S. The TiN coating provides a hard, wear-resistant surface layer that performs well across all four of these material groups, making this insert a versatile choice for job shops and production environments handling varied workpiece materials.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e35\/64-inch diameter with a 132-degree point angle for clean entry and controlled chip formation\u003c\/li\u003e\n\u003cli\u003eSolid carbide construction at manufacturer grade C2 (K20) for rigidity and wear resistance\u003c\/li\u003e\n\u003cli\u003eTiN PVD coating reduces cutting friction and extends insert service life\u003c\/li\u003e\n\u003cli\u003eCompatible with T-A Series Seat Size 0 spade drill holders\u003c\/li\u003e\n\u003cli\u003eRated for stainless steel, cast iron, non-ferrous metals, and super-alloys including titanium\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with T-A Series spade drill holders requiring a Seat Size 0 insert.
