Allied Machine and Engineering 1C22T-0101 Spade Drill Insert

Product Description

The ALLIED MACHINE AND ENGINEERING 1C22T-0101 is a solid carbide spade drill insert designed for high-performance drilling in demanding machining applications. Part of the T-A Series, this insert measures 1-1/32 inches in diameter and features a 132-degree point angle for accurate entry and chip control. It carries a TiN (titanium nitride) PVD coating applied over a C2 (K20) carbide grade substrate, providing surface hardness and wear resistance suited to aggressive cutting conditions. Machinists and tooling specialists install this insert into compatible T-A Series spade drill holders as a replaceable cutting element, extending holder life while maintaining consistent hole quality.

This insert is engineered for use across multiple workpiece material categories, including stainless steel, cast iron, non-ferrous metals, super-alloys, and titanium. It is a practical choice for production drilling in aerospace, general machining, and industrial manufacturing environments where tool change speed and repeatable hole geometry are priorities. The Seat Size 2 designation matches it to the corresponding T-A Series holder body for secure, indexed seating.

Key Features

• Solid carbide construction at C2 (K20) grade for hardness and thermal stability
• TiN PVD coating improves surface wear resistance and reduces built-up edge
• 132-degree point angle supports accurate hole entry and efficient chip evacuation
• 1-1/32 inch cutting diameter with 0.1875 inch insert thickness
• Seat Size 2 indexing for secure fit in T-A Series spade drill holders
• Rated for stainless steel, cast iron, non-ferrous metals, super-alloys, and titanium

Compatibility

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

Installation Notes

Installation is performed by a qualified machinist or tooling technician. Ensure the machine spindle is fully stopped and locked out before indexing or replacing the insert. Seat the insert fully into the holder pocket and torque the clamping screw to the holder manufacturer specification before resuming operation. Inspect the seat and clamping surfaces for chips or debris that could affect insert seating and hole accuracy.
