Allied Machine 10294-0516 Spade Drill Insert 5.5 in Seat H

Product Description

The ALLIED MACHINE AND ENGINEERING 10294-0516 is a spade drill insert designed for large-diameter boring operations in production and job-shop environments. Built from CPM-M4 powdered metal, this insert delivers high wear resistance and edge retention when drilling through demanding materials. It features a 130-degree point angle suited for general-purpose entry geometry and measures 5-1/2 inches in diameter with a height of 3-11/16 inches and a thickness of 0.6875 inches. The insert is uncoated and fits Seat Size H holders. Machinists and toolroom professionals install this type of insert into compatible spade drill bodies for through-hole and blind-hole applications.

This insert is intended for use in steel, cast iron, and non-ferrous metal workpiece materials, covering ISO material codes P, N, and K. Typical applications include high-volume hole-making on CNC machining centers, manual mills, and heavy-duty drill presses where large-diameter spade tooling is required. The uncoated CPM-M4 construction makes it a practical choice when re-grinding or reconditioning inserts is part of the shop workflow.
