Allied Machine 1C22A-0104 Spade Drill Insert 1-1/8 in

Product Description

The ALLIED MACHINE AND ENGINEERING 1C22A-0104 is a solid carbide spade drill insert designed for high-performance hole-making in demanding production environments. Built to T-A Series specifications, this insert measures 1-1/8 inches in diameter with a 132-degree point angle and a 0.1875-inch thickness. The TiAlN PVD coating extends tool life in abrasive and high-heat cutting conditions. Manufactured to C2 (K20) grade carbide, it delivers the hardness and wear resistance required for interrupted cuts and tight-tolerance bores. Machinists and tool-and-die professionals working with CNC drilling operations rely on this insert for consistent performance across a range of difficult workpiece materials.

This insert is suited for drilling stainless steel, cast iron, non-ferrous metals, and super-alloys including titanium. The T-A Series platform is a common choice in production machining shops running moderate to high spindle speeds where insert indexability reduces downtime. Seat Size 2 designates the blade holder pocket this insert is matched to, making it a direct fit for T-A Series holders configured for that seat size. It is applicable in both job-shop and high-volume manufacturing contexts where hole quality and tool longevity are priorities.

Installation Notes

Installation is performed by qualified machinists or toolroom technicians. Confirm the blade holder seat size matches the insert designation before seating the insert, and ensure the holder and spindle are fully secured before initiating a cut. Follow the machine tool manufacturer torque guidance for insert clamping hardware. Inspect the insert seating surface for chips or debris that could affect insert positioning and bore accuracy.
