Allied Machine 450H-16 Spade Drill Insert 16mm Cobalt AM200

Product Description

The ALLIED MACHINE AND ENGINEERING 450H-16 is a cobalt spade drill insert designed for use with GEN2 T-A series spade drill holders. The insert measures 16 mm in diameter with a 132-degree point angle and a seat size of 0. It carries an AM200 PVD coating, which improves wear resistance and extends tool life in demanding cutting applications. At 0.125 inches thick, the insert is engineered for precision hole-making in production environments. It is installed and replaced by machinists and tool-room professionals working on CNC lathes, machining centers, and drill presses.

This insert is suited for drilling operations in a wide range of workpiece materials, including steel, stainless steel, cast iron, super-alloys, titanium, and hard materials. It is compatible with ISO material classifications P, M, K, S, and H. The GEN2 T-A system is a common choice in high-volume production machining where insert indexability and repeatable hole quality are priorities. Applications span general manufacturing, aerospace component work, and heavy industrial fabrication where consistent bore diameter and finish are required.

Installation Notes

Installation and replacement of spade drill inserts should be performed by a qualified machinist with the machine fully powered down and the spindle locked. Use the correct torque wrench and insert screws specified for the GEN2 T-A holder to ensure proper clamping force without over-torquing the pocket. Inspect the holder pocket and locating surfaces for chips or wear before seating the new insert. Handle cobalt inserts carefully to avoid edge chipping prior to use.
