Product Description

The ALLIED MACHINE AND ENGINEERING 10254-0300 is a spade drill insert designed for high-performance hole-making in a range of industrial materials. Built from CPM-M4 powdered metal, this insert delivers the wear resistance and edge toughness required in demanding production drilling applications. It features a 130-degree point angle optimized for clean entry and chip control. The insert measures 3 inches in diameter with a seat size E designation and a thickness of 0.4375 inches and a height of 2.625 inches. It ships in an uncoated finish, making it suitable for use as-is or as a base for shop-applied coatings.

This spade drill insert is intended for use in seat size E spade drill holders on manual or CNC machining centers. It is rated for drilling into steel, cast iron, and non-ferrous metals, covering ISO material codes P, K, and N. Typical applications include production drilling in job shops, metalworking facilities, and manufacturing environments where large-diameter hole-making is required without the cost of solid carbide tooling.
