Product Description

The ALLIED MACHINE AND ENGINEERING 453H-39 is a spade drill insert designed for high-performance hole-making in demanding metalworking applications. The insert measures 39.00 mm in diameter with a 132-degree point angle and is manufactured from Super Cobalt with an AM200 PVD coating. Thickness is 0.25 inches. This insert is part of the GEN2 T-A series, a platform engineered for rigidity and chip control in production drilling environments. It is used by machinists and tool-and-die professionals running spade drill bodies in CNC machining centers or manual drill presses requiring precision bore diameters.

The 453H-39 insert is suited for drilling into a broad range of primary workpiece materials including Steel, Stainless Steel, Cast Iron, Superalloys and Titanium, and Hard Materials, corresponding to ISO material groups P, M, K, S, and H. Seat Size 3 designates the compatible T-A holder body size. This insert is a metric-system tool, making it appropriate for shops working to metric tolerances and print dimensions. Typical applications include batch production drilling, component manufacturing, and repair work where consistent hole quality and insert longevity are priorities.
