Part of the GEN2 T-A series, this insert measures 50 mm (1-31\/32 inches) in diameter and seats in a Size 4 holder. It is manufactured from M4-grade High Speed Steel and finished with a PVD-applied TiN (Titanium Nitride) coating that reduces friction and extends cutting life. The 132-degree point angle provides stable entry and chip control across a range of workpiece materials. At 0.16 pounds, it is a compact, direct-replacement insert intended for machinists, tool-and-die shops, and CNC drilling applications.\u003c\/p\u003e\u003cp\u003eThis insert is suited for drilling operations in steel, cast iron, and non-ferrous metals, corresponding to ISO material groups P, K, and N. Typical applications include production drilling on CNC machining centers and manual drill presses where a replaceable spade-style insert is used in place of a solid drill. The GEN2 T-A series holder system is a common platform in job shops and manufacturing environments where insert interchangeability and consistent hole quality are priorities.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e50 mm (1-31\/32 inches) cutting diameter in a Seat Size 4 format\u003c\/li\u003e\n\u003cli\u003eM4-grade High Speed Steel construction for toughness and wear resistance\u003c\/li\u003e\n\u003cli\u003ePVD TiN coating reduces heat buildup and increases tool life\u003c\/li\u003e\n\u003cli\u003e132-degree point angle for controlled entry and chip evacuation\u003c\/li\u003e\n\u003cli\u003eCompatible with P, K, and N ISO material groups: steel, cast iron, and non-ferrous metals\u003c\/li\u003e\n\u003cli\u003ePart of the GEN2 T-A series for broad holder compatibility\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with GEN2 T-A series Seat Size 4 spade drill holders.
