Built from cobalt (material grade T15) and finished with a TiN (titanium nitride) PVD coating, this insert delivers wear resistance and extended cutting life in tough materials. It features a 132-degree point angle and fits Seat Size 1 holders in the T-A spade drill series. At 0.1563 inches thick and sized for an 18 mm bore diameter, this insert is a direct fit for machinists and toolroom professionals running T-A series spade drill bodies on CNC lathes, machining centers, and drill presses.\u003c\/p\u003e\n\u003cp\u003eThis insert is suited for production and job-shop environments where consistent hole quality in ferrous and exotic materials is required. Primary workpiece materials include steel, stainless steel, cast iron, super-alloys, and titanium, making it a versatile choice for aerospace, automotive, oil and gas, and general precision machining operations. It is installed by machinists and toolroom technicians as a replacement or consumable insert in existing T-A series spade drill holders.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e18 mm cutting diameter for precise bore sizing in Seat Size 1 T-A holders\u003c\/li\u003e\n  \u003cli\u003eCobalt construction (T15 material grade) for high hardness and heat resistance\u003c\/li\u003e\n  \u003cli\u003eTiN PVD coating reduces friction and extends tool life in ferrous and exotic workpiece materials\u003c\/li\u003e\n  \u003cli\u003e132-degree point angle optimized for general-purpose drilling across a broad material range\u003c\/li\u003e\n  \u003cli\u003eRated for steel, stainless steel, cast iron, super-alloys, and titanium workpiece materials\u003c\/li\u003e\n  \u003cli\u003eSingle-piece package quantity suits toolcrib replenishment and individual replacement needs\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with T-A series Seat Size 1 spade drill holders.
