Allied Machine 454H-56 Spade Drill Insert 56mm Cobalt

Product Description

The ALLIED MACHINE AND ENGINEERING 454H-56 is a cobalt spade drill insert designed 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 across a wide range of workpiece materials. At 56 mm in diameter with a Seat Size 4 designation, it mounts into compatible T-A spade drill holders and is installed by machinists and toolroom professionals working in production or job-shop environments. The 0.3125-inch thickness and cobalt substrate provide the toughness needed for interrupted cuts and challenging alloys.

This insert is suited for drilling steel, stainless steel, cast iron, super-alloys, titanium, and hard materials. The GEN2 T-A platform is a common choice in CNC machining centers, manual lathes, and drill presses where consistent hole quality and insert interchangeability are priorities. The broad material compatibility makes the 454H-56 a practical stock item for shops running mixed-material production runs.
