Allied Machine 453H-37 Spade Drill Insert 37mm Cobalt GEN2 T-a

Product Description

The ALLIED MACHINE AND ENGINEERING 453H-37 is a cobalt spade drill insert engineered for high-performance hole-making in demanding machining environments. Sized at 37 mm in diameter with a 132-degree point angle, this insert fits Seat Size 3 holders in the GEN2 T-A spade drill system. The AM200 PVD coating is applied to the cobalt substrate, improving wear resistance and tool life across a range of workpiece materials. At 0.25 inches thick and 0.1 pounds, it is a compact, precision-ground component intended for installation by machinists and tooling specialists in production and job-shop settings.

This insert is designed for use in metal-cutting operations where consistent hole geometry and extended tool life are required. Its primary workpiece material compatibility covers steel, stainless steel, cast iron, super-alloys, titanium, and hard materials, making it a versatile choice for aerospace, automotive, oil and gas, and general metalworking applications. It is packaged individually and sold as a single-unit replacement insert for the GEN2 T-A spade drilling system.
