Allied Machine 483H-0124 Spade Drill Insert 1-3/4 in Cobalt

Product Description

The ALLIED MACHINE AND ENGINEERING 483H-0124 is a cobalt spade drill insert designed for high-performance hole-making in demanding machining applications. Measuring 1-3/4 inches in diameter with a 132-degree point angle and Seat Size 3, this insert is manufactured from Premium Cobalt with an AM200 PVD coating applied to extend tool life and reduce heat buildup at the cutting edge. It belongs to the GEN2 T-A Series and carries a thickness of 0.25 inches. Machining professionals and tool-crib operators working with production drilling operations will find this insert suited for consistent, repeatable performance across a range of workpiece materials.

This insert is intended for use in spade drill holder systems compatible with Seat Size 3 tooling. It is rated for use on primary workpiece materials including Steel, Stainless Steel, Cast Iron, Superalloys and Titanium, and Hard Materials, corresponding to ISO material groups P, M, K, S, and H. Typical applications include CNC machining centers and manual drill press setups where spade-style tooling is preferred for deep-hole or large-diameter drilling operations in industrial and production environments.
