Allied Machine 10244-0208 Spade Drill Insert 2-1/4 in Seat D

Product Description

The ALLIED MACHINE AND ENGINEERING 10244-0208 is a spade drill insert designed for high-feed drilling operations in metalworking and machining applications. Manufactured from CPM-M4 powdered metal, this uncoated insert measures 2-1/4 inches in diameter with a 130-degree point angle and a thickness of 0.375 inches. The seat size D configuration ensures positive seating and secure clamping in compatible spade drill holders. This insert is intended for use by machinists and tool-and-die professionals operating drill presses, machining centers, or CNC lathes requiring large-diameter hole production.

This insert is suited for drilling into steel, cast iron, and non-ferrous metals, covering ISO material groups P, K, and N. Its 130-degree point geometry provides a balance between centering performance and cutting edge strength, making it appropriate for through-hole and blind-hole applications in both production and job-shop environments. The 2-3/8 inch height accommodates deep-reach drilling setups where chip clearance and insert support are critical.
