Allied Machine 454T-0210 Spade Drill Insert 2-5/16 in Cobalt Tin

Product Description

The ALLIED MACHINE AND ENGINEERING 454T-0210 is a cobalt spade drill insert designed for high-performance hole-making in demanding machining applications. Built to Super Cobalt grade standards, this insert features a 132-degree point angle and a Physical Vapor Deposition (PVD) Titanium Nitride (TiN) coating that extends tool life and reduces friction during cutting. The insert measures 2-5/16 inches in diameter with a Seat Size 4 designation and a thickness of 0.3125 inches. Machinists and tooling specialists install this insert into compatible T-A style spade drill holders as part of the GEN2 T-A series platform. It is sold individually and weighs approximately 0.1 pounds.

This insert is engineered for production and job-shop environments where interrupted cuts, deep holes, and tough workpiece materials are common. The GEN2 T-A series is a modular spade drilling system suited for machining centers, lathes, and special-purpose drilling machines. The 454T-0210 is rated for use across a broad range of primary workpiece materials including Steel, Stainless Steel, Cast Iron, Superalloys and Titanium, and Hard Materials, corresponding to ISO material classifications P, M, K, S, and H. This makes it a versatile choice when a single insert must handle mixed-material production runs or specialty alloy components.

Key Features

Installation Notes

This insert is installed and replaced by machinists or tooling technicians. Always power down and lock out the machine spindle before changing inserts. Inspect the holder seat for chips, wear, or damage before seating the new insert, and ensure the clamping screw is torqued according to the holder manufacturer's documentation. Handle cobalt inserts with care to avoid edge chipping prior to use.
