Allied Machine 452H-0112 Spade Drill Insert 1-3/8 in Cobalt

Product Description

The ALLIED MACHINE AND ENGINEERING 452H-0112 is a cobalt spade drill insert designed for high-performance drilling in demanding metalworking applications. Part of the GEN2 T-A series, this insert features a 132-degree point angle and an AM200 PVD coating that extends tool life in abrasive and high-heat cutting environments. At 0.1875 inches thick and sized for a Seat Size 2 holder, it delivers consistent chip control and cutting geometry across a range of primary workpiece materials. Installed by machinists and tooling technicians, it fits standard spade drill blade holders used in CNC and manual machining operations.

This insert is suited for production drilling in steel, stainless steel, cast iron, super-alloys, titanium, and hard materials. The GEN2 T-A series is commonly applied in aerospace, oil and gas, die and mold, and general manufacturing environments where hole quality and tool longevity are critical. The AM200 PVD coating provides thermal stability and wear resistance, making this insert a dependable choice for interrupted cuts and continuous drilling cycles at elevated feed rates.

Installation Notes

Installation is performed by qualified machinists or tooling technicians. Power down and lock out the machine spindle before seating or removing the insert. Ensure the holder pocket and seating surfaces are clean and free of chips before installation, as debris under the insert will affect geometry and can cause premature failure. Follow the holder manufacturer torque specifications for the clamping screw.
