Allied Machine 454T-0215 Spade Drill Insert 2-15/32 in Cobalt

Product Description

The ALLIED MACHINE AND ENGINEERING 454T-0215 is a cobalt spade drill insert designed for high-performance drilling operations in demanding industrial applications. Measuring 2-15/32 inches in diameter with a Seat Size 4 designation, this insert fits the GEN2 T-A spade drill system. It features a 132-degree point angle and a Physical Vapor Deposition (PVD) TiN coating that improves wear resistance and extends cutting life. At 0.1 pounds, it is a lightweight yet robust cutting tool component. Machinists, toolroom technicians, and production drillers install this insert into compatible T-A style spade drill holders for precise, repeatable hole-making.

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. It is applicable in both job-shop and production-floor environments where a replaceable-insert spade drill system is used to achieve consistent hole diameter and reduced tooling cost. The GEN2 T-A series is a commonly used spade drill platform in metalworking operations involving deep or large-diameter holes.

Key Features

• 2-15/32 inches cutting diameter with Seat Size 4 for GEN2 T-A holder compatibility
• 132-degree point angle optimized for entry performance and chip formation
• Cobalt substrate provides high heat and wear resistance in tough workpiece materials
• PVD TiN coating extends tool life and reduces friction at the cutting edge
• Covers ISO material groups P, M, K, S, and H — steel through hard materials
• Sold individually, allowing single-insert replacement without holder replacement

Compatibility

Designed for use with GEN2 T-A series spade drill holders accepting a Seat Size 4 insert. Compatible workpiece materials include steel, stainless steel, cast iron, super-alloys, titanium, and hard materials (ISO groups P, M, K, S, and H).

Installation Notes

Installation is performed by qualified machinists or toolroom personnel following the holder manufacturer's insert seating and torque guidelines. Power down the machine spindle and verify it is fully stopped before removing or seating any insert. Inspect the holder pocket for chips or debris before installing the new insert, as foreign material in the seat can cause insert breakage or runout. Follow applicable shop safety procedures and machine tool manufacturer guidelines during all tooling changes.
