Allied Machine 454H-61.5 Spade Drill Insert 2-27/64 in Cobalt

Product Description

The ALLIED MACHINE AND ENGINEERING 454H-61.5 is a cobalt spade drill insert designed for high-performance hole-making in demanding metalworking applications. Built to Super Cobalt grade standards, this insert features a 132-degree point angle and an AM200 PVD coating for extended tool life and heat resistance. It measures 2-27/64 inches in diameter with a 0.3125-inch thickness and fits Seat Size 4 toolholders. It is part of the GEN2 T-A series, a platform recognized in industrial drilling for its precision and repeatability. Licensed machinists and toolroom technicians are the primary installers.

This insert is suited for production drilling in steel, stainless steel, cast iron, superalloys, and titanium, as well as hard materials. The GEN2 T-A series is commonly found on CNC machining centers, lathes with live tooling, and dedicated drill presses used in aerospace, automotive, and general metalworking environments. The AM200 PVD coating reduces built-up edge and improves performance in difficult-to-machine alloys. Each package contains one insert, making it straightforward to order exact replacement quantities.

Installation Notes

Installation is performed by qualified machinists or toolroom technicians. Before changing an insert, ensure the machine spindle is fully stopped and locked out per applicable machine safety procedures. Seat and clamping surfaces should be cleaned and inspected for wear or debris before seating the new insert. Use the correct torque wrench and manufacturer-specified fasteners for the spade drill body to avoid insert shifting under load.
