Allied Machine 1C22A-0031 Spade Drill Insert 31/32 in Carbide

Product Description

The ALLIED MACHINE AND ENGINEERING 1C22A-0031 is a solid carbide spade drill insert designed for high-performance hole-making in demanding machining applications. Measuring 31/32 inches in diameter with a 132-degree point angle, this insert seats into a Series T-A holder at Seat Size 2. The TiAlN (titanium aluminum nitride) PVD coating provides thermal resistance and wear resistance, extending tool life in abrasive and hard materials. At 0.1875 inches thick and weighing approximately 0.1 pounds, it is a compact, precision-ground cutting tool. Licensed machinists and CNC operators install this insert as part of a modular drilling system on standard machining centers and drill presses.

This insert is rated for use in stainless steel, cast iron, non-ferrous metals, super-alloys, and titanium, covering ISO workpiece material groups M, K, N, and S. The Manufacturer Grade C2 (K20) carbide substrate is well-suited for these material families, which span a broad range of production and job-shop environments. Typical applications include through-hole and blind-hole drilling in aerospace, oil and gas, and general manufacturing, where consistent hole diameter and tool life are critical. The T-A Series modular system allows the insert to be replaced without removing the holder from the spindle.

Key Features

• 132-degree point angle suited to stainless steel, super-alloys, and titanium drilling
• Seat Size 2 fits standard T-A Series spade drill holders for quick insert changes
• Rated for ISO material groups M, K, N, and S covering a wide range of production materials
• Compact 0.1875-inch insert thickness for precise seating and repeatable hole geometry

Compatibility

Designed for use with T-A Series Seat Size 2 spade drill holders. Compatible workpiece materials include stainless steel, cast iron, non-ferrous metals, super-alloys, and titanium as specified by the manufacturer.

Installation Notes

Installation is performed by qualified machinists or CNC operators. Power down and lock out the machine spindle before seating or removing the insert. Use the appropriate T-A Series insert wrench or torx key as specified for the holder; do not overtighten or substitute fasteners. Inspect the insert seat for chips or debris before seating the new insert to ensure proper contact and runout.
