Allied Machine 454H-52 Spade Drill Insert 2-3/64 in Cobalt

Product Description

The ALLIED MACHINE AND ENGINEERING 454H-52 is a cobalt spade drill insert engineered for high-performance hole-making in demanding metalworking applications. Part of the GEN2 T-A series, this insert features a 132-degree point angle and an AM200 PVD coating that extends tool life in abrasive and hard workpiece materials. At 0.3125 inches thick and sized for a Seat Size 4 holder, the 454H-52 is designed to deliver consistent chip control and cutting stability. Machinists and CNC operators working in production environments rely on inserts like this one to maintain tight hole tolerances without frequent tool changes.

The 454H-52 is suited for drilling operations in steel, stainless steel, cast iron, super-alloys, titanium, and hard materials, covering ISO workpiece material codes P, M, K, S, and H. It fits standard GEN2 T-A Seat Size 4 spade drill holders and is appropriate for both vertical machining centers and horizontal boring mill setups where consistent penetration rates and hole quality are required. The 2-3/64 inch diameter makes it a practical choice for medium-to-large diameter hole applications in job shop and production environments alike.

Key Features

• 2-3/64 inch cutting diameter for medium-to-large bore applications
• 132-degree point angle promotes clean entry and reduced thrust force
• Cobalt substrate provides toughness and heat resistance in hard materials
• AM200 PVD coating extends wear resistance across a broad range of workpiece materials
• GEN2 T-A series design for compatibility with Seat Size 4 spade drill holders
• Rated for steel, stainless steel, cast iron, super-alloys, titanium, and hard materials

Compatibility

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

Installation Notes

Installation is performed by qualified machinists or CNC tooling technicians. The machine spindle must be fully stopped and the tool holder secured before seating or removing the insert. Inspect the holder seat for chips or debris before installation, as contamination can affect insert seating and hole accuracy. Follow the holder manufacturer's torque and clamping guidelines for Seat Size 4 inserts.
