Allied Machine 1C22A-0112 Spade Drill Insert 1-3/8 in Solid Carbide

Product Description

The ALLIED MACHINE AND ENGINEERING 1C22A-0112 is a solid carbide spade drill insert designed for high-performance hole-making in demanding machining applications. Built to T-A series specifications, this insert seats into a Size 2 holder and features a 132-degree point angle optimized for clean entry and chip control. The TiAlN PVD coating provides thermal resistance and extended tool life when cutting hard and abrasive materials. At 0.1875 inches thick and 1-3/8 inches in diameter, this insert is a direct-fit replacement for T-A series tooling setups. It is installed by machinists and tooling technicians in CNC and manual drilling operations.

This insert is suited for drilling stainless steel, cast iron, non-ferrous metals, super-alloys, and titanium. The TiAlN coating and C2 (K20) carbide grade make it particularly effective in high-temperature cutting environments where tool wear is a primary concern. Typical applications include production drilling in aerospace, automotive, and general metalworking operations where consistent hole diameter and finish are critical. The fractional inch sizing makes it compatible with standard imperial tooling setups.

Compatibility

Designed for use with T-A series Seat Size 2 spade drill holders. Compatible with primary workpiece materials including stainless steel, cast iron, non-ferrous metals, super-alloys, and titanium (material codes M, K, N, S).

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 seat is clean and free of chips before installing the insert, as debris can cause misalignment and premature insert failure. Follow the tooling manufacturer's clamping procedure for T-A series holders to achieve proper seating and secure retention.
