Allied Machine 453T-0116 Spade Drill Insert 1-1/2 in Cobalt Tin

Product Description

The ALLIED MACHINE AND ENGINEERING 453T-0116 is a cobalt spade drill insert designed for high-performance drilling in demanding industrial machining applications. Measuring 1-1/2 inches in diameter with a 132-degree point angle, this insert fits Seat Size 3 holders in the GEN2 T-A spade drill system. The insert is finished with a TiN (titanium nitride) PVD coating, which reduces friction and extends cutting life. At 0.25 inches thick and manufactured from M4-grade cobalt, it delivers consistent chip formation and edge retention across high-feed drilling cycles. Machining professionals and tooling specialists select this insert for production drilling where tool life and hole quality are critical.

The 453T-0116 is suited for drilling steel, stainless steel, cast iron, super-alloys, titanium, and hard materials across ISO material groups P, M, K, S, and H. It is used in CNC machining centers, lathes, and dedicated drill presses in both job-shop and high-volume production environments. The GEN2 T-A system is a modular spade drill platform, and this insert is a consumable component that indexes into a reusable holder body. Typical applications include through-hole and blind-hole drilling in structural components, flanges, and heavy equipment parts.

Compatibility

Designed for use with Seat Size 3 holders in the ALLIED MACHINE AND ENGINEERING GEN2 T-A spade drill system. Compatible workpiece materials include steel, stainless steel, cast iron, super-alloys, titanium, and hard materials (ISO groups P, M, K, S, and H).

Installation Notes

Installation is performed by machining professionals or qualified toolroom technicians. Secure the insert fully into the holder seat before operation and verify seating with a visual inspection before spindle engagement. Always power down and lock out the machine before changing inserts. Follow the tool manufacturer torque guidance for the holder clamping screw to avoid seat damage or insert movement during cutting.
