Allied Machine 450H-0022 Spade Drill Insert 11/16 in Cobalt

Product Description

The ALLIED MACHINE AND ENGINEERING 450H-0022 is a cobalt spade drill insert designed for high-performance drilling in demanding metalworking applications. This insert measures 11/16 inches in diameter and seats in a Size 0 holder. It features a 132-degree point angle and a 0.125-inch thickness. The AM200 PVD coating enhances wear resistance and extends tool life when cutting through tough workpiece materials. Licensed machinists and toolroom professionals install this insert as part of the GEN2 T-A spade drill system.

This insert is suited for production and job-shop drilling operations across a broad range of metallic workpiece materials. The GEN2 T-A series is engineered for use in CNC machining centers and manual drilling setups where interchangeable spade drill inserts are preferred over solid carbide or indexable alternatives. Typical applications include through-hole and blind-hole drilling in ferrous and non-ferrous stock.
