Allied Machine 452H-0031 Spade Drill Insert 31/32 in Cobalt

Product Description

The ALLIED MACHINE AND ENGINEERING 452H-0031 is a cobalt spade drill insert designed for high-performance hole-making in demanding machining applications. Part of the GEN2 T-A series, this insert measures 31/32 inches in diameter and carries a 132-degree point angle for reliable chip formation and accurate entry. The AM200 PVD coating enhances wear resistance and extends tool life across a broad range of workpiece materials. At 0.1875 inches thick, this insert fits Seat Size 2 holders and is installed by machinists and toolroom technicians in production and job-shop environments.

This insert is suited for drilling steel, stainless steel, cast iron, super-alloys, titanium, and hard materials, covering ISO material groups P, M, K, S, and H. The GEN2 T-A spade drill system is commonly used in CNC machining centers, lathes, and dedicated drilling equipment where interchangeable insert geometry reduces tooling cost compared to solid drills. Typical applications include through-holes and blind holes in structural components, flanges, and machined parts across aerospace, automotive, and general metalworking industries.

Key Features

• Cobalt insert material provides toughness and heat resistance in difficult-to-machine alloys
• AM200 PVD coating reduces friction and improves wear life across multiple material groups
• 132-degree point angle supports accurate entry and efficient chip evacuation
• Seat Size 2 design for direct interchange within the GEN2 T-A holder system
• 0.1875-inch insert thickness for consistent seating and repeatability
• Covers ISO material groups P, M, K, S, and H for broad application range

Compatibility

Designed for use with Seat Size 2 holders in the Allied Machine and Engineering GEN2 T-A spade drill system. Compatible workpiece materials include steel, stainless steel, cast iron, super-alloys, titanium, and hard materials as specified by the manufacturer.

Installation Notes

Installation is performed by a qualified machinist or toolroom technician. Ensure the holder is removed from the machine spindle and all machine power is off before seating or removing the insert. Use the correct insert screw and torque driver specified for the GEN2 T-A holder to secure the insert without damaging the seat. Inspect the holder seat for wear or debris before each insert change to maintain positional accuracy.
