Allied 153A-0118 Spade Drill Insert 1-9/16 in Cobalt Tialn

Product Description

The ALLIED MACHINE AND ENGINEERING 153A-0118 is a spade drill insert engineered for high-performance drilling in demanding industrial applications. Manufactured from Super Cobalt and finished with a TiAlN (Titanium Aluminum Nitride) PVD coating, this insert delivers elevated heat resistance and extended tool life at aggressive feed rates. It features a 132-degree point angle optimized for fast penetration and chip control. The insert measures 1-9/16 inches in diameter with a 0.25-inch thickness and fits Seat Size 3 holders. It belongs to the T-A Series, a widely recognized modular spade drill platform used by machinists and tool-and-die professionals across production and job-shop environments.

This insert is suited for drilling steel, stainless steel, cast iron, superalloys, and titanium — covering ISO material codes P, M, K, and S. It performs in both CNC machining centers and manual drill press setups where consistent hole quality and tool longevity are priorities. The TiAlN coating maintains hardness at elevated cutting temperatures, making it a practical choice for interrupted cuts and high-speed drilling cycles on ferrous and difficult-to-machine materials.

Key Features

• Super Cobalt substrate for increased hardness and heat resistance versus standard cobalt grades
• TiAlN PVD coating extends tool life in high-temperature cutting conditions
• 132-degree point angle promotes aggressive chip breaking and reduced thrust force
• 1-9/16 inch diameter, Seat Size 3, compatible with T-A Series modular spade drill holders
• Rated for steel, stainless steel, cast iron, superalloys, and titanium workpiece materials
• Fractional inch measurement system for straightforward sizing in standard machining environments

Compatibility

Designed for use with T-A Series Seat Size 3 spade drill holders. Consult your holder documentation to confirm insert seat size before installation.

Installation Notes

Spade drill inserts of this type are installed and serviced by qualified machinists or tooling technicians. Ensure the machine spindle is fully stopped and energy is isolated before changing inserts. Seat the insert firmly and evenly in the holder pocket, and inspect the seat for chips or debris before clamping. Follow the holder manufacturer torque and clamping specifications for the T-A Series Seat Size 3 interface.
