Allied Machine 180A-.640 Spade Drill Insert 41/64 in Cobalt

Product Description

The ALLIED MACHINE AND ENGINEERING 180A-.640 is a cobalt spade drill insert designed for high-performance hole-making operations in demanding machining environments. Measuring 41/64 inches in diameter with a 132-degree point angle, this insert is engineered for accurate, controlled penetration across a range of workpiece materials. The 0.125-inch thickness and Seat Size 0 configuration position it in the T-A series platform, a widely used modular spade drill system. A PVD-applied TiAlN coating adds surface hardness and heat resistance, extending tool life in high-speed and high-feed applications. This insert is typically installed and managed by machining professionals and toolroom technicians.

This insert is suited for drilling operations in steel, stainless steel, cast iron, super-alloys, titanium, and hard materials. It fits into T-A series spade drill holders using the Seat Size 0 interface, making it appropriate for CNC machining centers, lathes, and drilling stations in both production and job-shop environments. The TiAlN coating supports dry or minimal-lubrication cutting strategies in hard and abrasive materials. This part is sold individually with a minimum order quantity of 2 units.
