Part of the T-A series, this insert measures 15\/16 inches in diameter and features a 132-degree point angle. It is manufactured from cobalt and finished with a TiCN (Titanium Carbonitride) PVD coating that extends tool life and reduces friction at the cutting edge. The insert seats in a Size 1 holder and has a thickness of 0.1563 inches. It is installed by machinists and tool-and-die professionals working with spade drill systems on CNC or manual machine tools.\u003c\/p\u003e\u003cp\u003eThis insert is suited for production drilling operations across a range of workpiece materials including steel, stainless steel, cast iron, super-alloys, titanium, and hard materials. The T-A series spade drill system is widely used in job shops and manufacturing facilities where indexable, replaceable inserts reduce tooling cost and setup time compared to solid drills. The 15\/16-inch diameter makes it appropriate for medium-bore hole applications in structural, aerospace, and general machining contexts.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e15\/16 inch diameter with a 132-degree point angle for accurate hole entry and reduced thrust\u003c\/li\u003e\n\u003cli\u003eCobalt insert material provides toughness and heat resistance in interrupted cuts\u003c\/li\u003e\n\u003cli\u003eTiCN PVD coating improves wear resistance and reduces built-up edge on difficult materials\u003c\/li\u003e\n\u003cli\u003eSeat Size 1 interface for direct fit into compatible T-A series spade drill holders\u003c\/li\u003e\n\u003cli\u003e0.1563 inch insert thickness for consistent seating and rigidity\u003c\/li\u003e\n\u003cli\u003eRated for use in steel, stainless steel, cast iron, super-alloys, titanium, and hard materials\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with T-A series Seat Size 1 spade drill holders.
