Allied Machine 454H-0211 Spade Drill Insert 2-11/32 in Cobalt

Product Description

The ALLIED MACHINE AND ENGINEERING 454H-0211 is a cobalt spade drill insert designed for high-performance hole-making in demanding industrial drilling applications. Part of the GEN2 T-A series, this insert features a 132-degree point angle and a 2-11/32-inch diameter, making it well-suited for drilling through tough workpiece materials. The insert is manufactured from T15 cobalt material grade and finished with an AM200 PVD coating that extends tool life in abrasive and high-temperature cutting environments. Licensed machinists and toolroom professionals install this insert into compatible T-A spade drill holders for precision boring operations.

This insert is intended for use in production and job-shop drilling environments where material versatility is required. Its primary workpiece material compatibility spans steel, stainless steel, cast iron, super-alloys and titanium, and hard materials, covering ISO material codes P, M, K, S, and H. It fits Seat Size 4 T-A series spade drill bodies, making it a practical choice for machining centers, CNC lathes, and radial arm drill setups handling medium-to-large diameter holes.
