Allied Machine 1C22A-0107 Spade Drill Insert 1-7/32 in

Product Description

The ALLIED MACHINE AND ENGINEERING 1C22A-0107 is a solid carbide spade drill insert engineered for high-performance hole-making in demanding industrial applications. Sized at 1-7/32 inches in diameter with a Seat Size 2 designation, this insert fits Allied T-A series spade drill holders and delivers a 132-degree point angle optimized for accurate, low-thrust entry. The insert is finished with a TiAlN (titanium aluminum nitride) PVD coating that extends tool life by resisting heat and oxidation at elevated cutting speeds. Manufactured to grade C2 (K20), it is suited for production environments where tool consistency and edge integrity are critical. Machining professionals and toolroom technicians specify this insert for demanding materials and high-volume runs.

This insert is designed for use in machining operations where workpiece materials include stainless steel, cast iron, non-ferrous metals, super-alloys, and titanium. The T-A series platform is a common choice in production shops running CNC machining centers and drill presses that require repeatable, indexable tooling without regrinding. Typical applications include flange drilling, plate work, and deep-hole operations across aerospace, industrial, and energy-sector workpieces.

Key Features

• 1-7/32 inch diameter with Seat Size 2 for precise holder fitment in T-A series bodies
• 132-degree point angle for accurate self-centering entry and reduced thrust
• Solid carbide construction at grade C2 (K20) for rigidity and edge retention
• TiAlN PVD coating resists heat and oxidation for extended tool life at higher surface speeds
• Compatible with stainless steel, cast iron, non-ferrous metals, super-alloys, and titanium workpieces
• Indexable insert design eliminates regrinding downtime

Compatibility

Designed for use with Allied Machine T-A series Seat Size 2 spade drill holders. Suitable for primary workpiece materials including stainless steel, cast iron, non-ferrous metals, super-alloys, and titanium.

Installation Notes

Installation is performed by qualified machinists or toolroom technicians. Ensure the drill holder and machine spindle are fully stopped and locked out before seating or removing the insert. Verify the seat and insert pocket are clean and free of chips before torquing the insert screw. Follow the tool holder manufacturer's specified insert retention procedure to avoid edge chipping or premature failure.
