Allied Machine 10244-0216 Spade Drill Insert 2.5in Seat D

Product Description

The ALLIED MACHINE AND ENGINEERING 10244-0216 is a spade drill insert designed for high-performance drilling in demanding metalworking applications. Manufactured from CPM-M4 powdered metal, this insert measures 2.5 inches in diameter and 2.375 inches in height with a 0.375-inch thickness. The 130-degree point angle promotes aggressive cutting action and efficient chip evacuation. Left in an uncoated finish, the CPM-M4 grade delivers strong wear resistance and toughness across a wide range of workpiece materials. Machinists, tool-and-die professionals, and production drilling operators rely on this insert for consistent hole quality in medium to high-volume operations.

This insert fits Seat Size D spade drill holders and is suited for drilling steel, cast iron, and non-ferrous metals. The ISO material group classifications P, N, and K confirm its compatibility with these primary workpiece categories. Typical applications include deep-hole drilling on CNC machining centers, horizontal boring mills, and production lathes where spade tooling is preferred over indexable or solid carbide alternatives for larger diameter holes.

Installation Notes

Installation should be performed by a qualified machinist or tooling technician. Power down and lock out the machine spindle before inserting or removing the drill insert. Ensure the holder seat is clean and free of chips or burrs before seating the insert to maintain proper alignment and cutting geometry. Follow the machine tool manufacturer and tooling manufacturer guidelines for clamping hardware and setup procedures.
