Allied Machine 1C22T-0103 Spade Drill Insert 1-3/32 in Carbide

Product Description

The ALLIED MACHINE AND ENGINEERING 1C22T-0103 is a solid carbide spade drill insert designed for high-performance drilling in demanding industrial applications. Part of the T-A series, this insert features a 132-degree point angle and a TiN (titanium nitride) PVD coating that extends tool life by reducing friction and heat buildup at the cutting edge. It carries a manufacturer grade of C2 (K20), indicating a fine-grained carbide substrate well-suited for interrupted cuts and hard materials. The insert measures 1-3/32 inches in diameter and seats into a Size 2 T-A series spade drill holder. Machinists and tooling specialists install this insert in CNC machining centers and drill presses where precision boring is required.

This insert is intended for use on a range of primary workpiece materials, including stainless steel, cast iron, non-ferrous metals, and super-alloys and titanium. The TiN coating and C2 carbide grade make it a practical choice for production environments where tool changes need to be minimized and consistent hole quality is required across varied material types. It is commonly used in aerospace, automotive, and general metalworking shops running medium to high spindle speeds on rigid machine setups.

Key Features

• 1-3/32 inch diameter fits Size 2 T-A series spade drill holders
• Solid carbide construction with C2 (K20) manufacturer grade for rigidity and wear resistance
• 132-degree point angle provides self-centering entry and reduces thrust load
• TiN PVD coating reduces friction and extends insert service life
• Rated for stainless steel, cast iron, non-ferrous metals, and super-alloys including titanium
• Single-insert package quantity simplifies replacement ordering

Compatibility

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

Installation Notes

Installation is performed by a trained machinist or tooling technician. The machine spindle must be fully stopped and locked out before seating or removing the insert. Confirm the holder seat is clean and free of chips or debris before inserting, as contamination will affect seating accuracy and hole quality. Follow the T-A holder manufacturer torque and clamping guidelines for the Size 2 seat.
