The insert measures 41\/64 inches in diameter with a 132-degree point angle and is manufactured from Super Cobalt material. It features an AM200 PVD coating that extends tool life and improves performance in abrasive and hard materials. The 0.125-inch thickness and Seat Size 0 profile make it compatible with the GEN2 T-A spade drill system. This insert is intended for use by machinists, tool and die professionals, and production drilling operations working in metal fabrication environments.\u003c\/p\u003e\u003cp\u003eThe 450H-.640 is rated for use across a broad range of primary workpiece materials including steel, stainless steel, cast iron, superalloys, titanium, and hard materials. These material compatibility designations correspond to ISO material codes P, M, K, S, and H. It fits into the GEN2 T-A holder series, which is a modular spade drill platform common in CNC machining centers and manual drill press setups requiring precise, repeatable hole geometry in production or job shop environments.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e41\/64-inch diameter with a 132-degree point angle for controlled entry and reduced thrust in harder materials\u003c\/li\u003e\n\u003cli\u003eSuper Cobalt insert material provides elevated heat and wear resistance compared to standard HSS inserts\u003c\/li\u003e\n\u003cli\u003eAM200 PVD coating classification improves surface hardness and lubricity across all rated material groups\u003c\/li\u003e\n\u003cli\u003eSeat Size 0 insert profile fits GEN2 T-A spade drill holders directly\u003c\/li\u003e\n\u003cli\u003eRated for steel, stainless steel, cast iron, superalloys, titanium, and hard materials (ISO P, M, K, S, H)\u003c\/li\u003e\n\u003cli\u003eFractional inch system sizing for straightforward integration with inch-based tooling setups\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with GEN2 T-A series spade drill holders.
