Allied Machine 453H-0116 Spade Drill Insert 1-1/2 in

Product Description

The ALLIED MACHINE AND ENGINEERING 453H-0116 is a spade drill insert designed for high-performance hole-making in demanding metalworking applications. Manufactured from Super Cobalt with an AM200 PVD coating, this insert delivers extended tool life and thermal resistance in tough cutting conditions. It measures 1-1/2 inches in diameter, carries a Seat Size 3 designation, and features a 132-degree point angle optimized for controlled entry and reduced thrust in production drilling. At 0.1 pounds, it is a precision indexable component intended for use by machinists and tooling professionals operating Allied Machine T-A spade drill holders.

This insert is part of the GEN2 T-A series from Allied Machine and Engineering, engineered for fractional inch drilling in steel, stainless steel, cast iron, superalloys, titanium, and hard materials. It is suited to CNC machining centers and production drilling operations in job shops, aerospace, and heavy manufacturing environments where consistent hole geometry and insert longevity are priorities. The AM200 PVD coating provides wear resistance across a broad range of workpiece materials, making this insert a versatile choice for mixed-material production runs.

Installation Notes

Insert installation should be performed by a qualified machinist or tooling technician. Ensure the spade drill holder and seat are clean and free of chips before seating the insert. Secure the insert with the appropriate torque wrench per the holder manufacturer's specifications, and verify clamp screw integrity before initiating a cut. Always power down and lock out the machine spindle before performing any insert change.
