Allied Machine 1C22T-0112 Spade Drill Insert 1-3/8 in

Product Description

The ALLIED MACHINE AND ENGINEERING 1C22T-0112 is a solid carbide spade drill insert designed for high-performance drilling applications in demanding materials. Part of the T-A series, this insert measures 1-3/8 inches in diameter and seats in a Size 2 holder. It features a 132-degree point angle and a TiN (titanium nitride) PVD coating applied to a C2 (K20) carbide grade substrate. The TiN coating reduces friction and extends tool life in production drilling environments. This insert is intended for use by machinists and tool and die professionals running spade drill operations on CNC or manual equipment.

The 1C22T-0112 is rated for primary workpiece materials including stainless steel, cast iron, non-ferrous metals, super-alloys, and titanium. The T-A series system is a modular spade drill platform that separates the insert from the holder, allowing quick changeout without removing the body from the spindle. This makes it well suited for production environments where minimizing downtime is critical. Typical applications include through-hole and blind-hole drilling in job shop, aerospace, and general manufacturing settings where material hardness and abrasion resistance demand a carbide cutting edge.

Key Features

• Solid carbide construction in manufacturer grade C2 (K20) for hardness and wear resistance
• TiN PVD coating reduces heat buildup and improves surface finish in abrasive materials
• 132-degree point angle optimized for a range of workpiece materials including stainless steel and super-alloys
• T-A series modular design allows insert replacement without removing the holder body
• 1-3/8 inch diameter with Size 2 seat for direct compatibility with T-A series holders
• 0.1875 inch insert thickness provides rigidity at this diameter range

Compatibility

Designed for use with Allied Machine and Engineering T-A series Size 2 spade drill holders. Compatible with workpiece materials coded M (stainless steel), K (cast iron), N (non-ferrous metals), and S (super-alloys and titanium).

Installation Notes

Installation is performed by machinists or tooling setup personnel. Before inserting or removing a spade drill insert, confirm the machine spindle is fully stopped and the tool holder is secured. Use the appropriate torx or insert screw driver specified for the T-A holder to seat the insert flush and secure the clamping screw to the holder manufacturer torque specification. Inspect the insert seat and clamping surfaces for chips or debris before each installation to ensure proper seating and runout.
