Allied 180N-0022 Spade Drill Insert 11/16 in 132 Deg Cobalt

Product Description

The ALLIED MACHINE AND ENGINEERING 180N-0022 is a spade drill insert designed for high-performance drilling in demanding industrial applications. Measuring 11/16 inches in diameter and 0.125 inches thick, this insert features a 132-degree point angle optimized for controlled entry and accurate hole placement. It is manufactured from Premium Cobalt and finished with a PVD-applied TiCN coating, which increases surface hardness and extends tool life in abrasive or high-heat cutting conditions. The T-A Series designation identifies it as part of Allied's modular spade drill system, where the insert mounts into a compatible holder body. Machinists and CNC operators in production machining environments are the primary users.

This insert is suited for drilling steel, stainless steel, cast iron, superalloys, titanium, and hard materials. The ISO material group codes covered are P, M, K, S, and H, making it a versatile choice across a wide range of workpiece materials. Typical applications include through-hole and blind-hole drilling on machining centers, lathes with live tooling, and dedicated drill presses running moderate to high feed rates. Seat Size 0 identifies the correct holder size required for this insert within the T-A system.

Installation Notes

Installation is performed by a qualified machinist or CNC technician. Ensure the machine spindle is fully stopped and the machine is in a safe, locked-out state before changing inserts. Seat the insert fully and evenly in the holder pocket and secure the clamping screw to the holder manufacturer's specified procedure. Inspect the seating surface and clamping mechanism for wear or debris before each insert change to maintain runout accuracy.
