Allied Machine 180A-.609 Spade Drill Insert 39/64 in Cobalt

Product Description

The ALLIED MACHINE AND ENGINEERING 180A-.609 is a spade drill insert designed for high-performance hole-making in demanding machining environments. Built from premium cobalt steel and coated with a physical vapor deposition (PVD) TiAlN finish, this insert delivers heat resistance and edge retention at elevated cutting speeds. It features a 132-degree point angle and measures 39/64 inches in diameter with a thickness of 0.125 inches. Seat Size 0 keeps it compatible with the T-A spade drill holder system. Machining professionals and toolroom technicians rely on this insert for consistent, repeatable results in production drilling operations.

This insert is suited for drilling operations in steel, stainless steel, cast iron, superalloys, titanium, and hard materials. It fits within the T-A series spade drill system and is intended for use in machining centers, lathes, and manual drill press setups where replaceable insert tooling is preferred over solid-carbide or high-speed steel alternatives. The fractional inch sizing makes it a direct fit for shops operating on inch-based tooling standards. It is sold individually and is appropriate for both job-shop and production-floor use.

Installation Notes

Insert installation should be performed by a qualified machinist or toolroom technician. Ensure the spade drill holder is fully removed from the spindle and the machine is powered down and locked out before handling or replacing inserts. Use the correct torque driver or wrench for the holder seat screw to avoid damaging the seating surface. Inspect the holder seat for chips or wear before seating the new insert.
