Allied Machine 454H-51 Spade Drill Insert 51mm Cobalt

Product Description

The ALLIED MACHINE AND ENGINEERING 454H-51 is a cobalt spade drill insert designed for high-performance hole-making in demanding machining applications. Built to Seat Size 4 and measuring 51.00 mm in diameter, this insert features a 132-degree point angle and is manufactured from Super Cobalt substrate with an AM200 PVD coating. The AM200 coating enhances wear resistance and thermal stability, extending tool life in production environments. It belongs to the GEN2 T-A series, a modular spade drilling system widely used in CNC machining centers and manual drilling operations across metalworking shops.

This insert is engineered for use across a broad range of workpiece materials, including steel, stainless steel, cast iron, superalloys, titanium, and hard materials. It is well-suited for high-volume production drilling in aerospace, automotive, and general machining environments where consistent hole quality and tool longevity are critical. The GEN2 T-A modular system allows the insert to be paired with compatible T-A spade drill holders, enabling quick insert changes without removing the holder from the spindle.

Key Features

• 51.00 mm cutting diameter with Seat Size 4 for precise holder fitment

Installation Notes

Installation is performed by qualified machinists or tooling technicians. Ensure the spindle is fully stopped and the machine is locked out before changing inserts. Seat the insert firmly into the holder pocket and secure with the appropriate torque driver per the holder manufacturer's instructions. Inspect the holder seat for wear or debris before installing a new insert to ensure proper seating and runout performance.
