Allied 453H-0123 Spade Drill Insert 1-23/32 in Cobalt

Product Description

The ALLIED MACHINE AND ENGINEERING 453H-0123 is a cobalt spade drill insert designed for high-performance drilling in demanding industrial applications. Built to GEN2 T-A series specifications, this insert features a 132-degree point angle and an AM200 PVD coating that extends tool life in abrasive and hard-to-machine materials. The insert measures 1-23/32 inches in diameter with a Seat Size 3 designation and a thickness of 0.25 inches. Manufactured from Super Cobalt grade material, it delivers consistent performance in production environments where standard HSS inserts fall short. Installation is handled by machinists and toolroom technicians working with compatible T-A spade drill bodies.

This insert is suited for drilling steel, stainless steel, cast iron, superalloys, titanium, and hard materials, covering ISO material groups P, M, K, S, and H. The GEN2 T-A series is a widely used platform in production machining shops, contract manufacturing, and heavy industry. Typical applications include through-hole and blind-hole drilling in workpieces where precise diameter control and tool longevity are critical. The AM200 PVD coating helps reduce built-up edge and heat generation at the cutting zone, making it effective across a broad range of cutting conditions.

Key Features

• 1-23/32 inch diameter with Seat Size 3 for GEN2 T-A spade drill bodies
• 132-degree point angle optimized for entry accuracy and chip control
• Super Cobalt insert material for improved hardness and heat resistance over standard cobalt
• AM200 PVD coating reduces friction and extends cutting edge life
• Compatible with ISO workpiece material groups P, M, K, S, and H
• Fractional inch measurement system for straightforward sizing in imperial tooling setups

Compatibility

Designed for use with GEN2 T-A series spade drill bodies accepting a Seat Size 3 insert. Verify body seat size and clamping screw specifications before installation.

Installation Notes

Insert replacement should be performed by a qualified machinist with the machine fully powered down and locked out per OSHA lockout/tagout procedures. Use the correct torque driver and clamping hardware specified for the T-A series body to seat the insert securely. Inspect the insert pocket and clamping screw for wear or damage before installing a new insert. Do not force or modify the insert to fit a non-compatible body seat.
