Allied Machine 180A-0020 Spade Drill Insert 5/8 in Cobalt

Product Description

The ALLIED MACHINE AND ENGINEERING 180A-0020 is a cobalt spade drill insert designed for high-performance hole making in demanding machining applications. Part of the T-A Series, this insert measures 5/8 inch in diameter with a 132-degree point angle and a 0.125-inch thickness. The TiAlN PVD coating provides thermal resistance and extended tool life under high cutting speeds. It seats into Seat Size 0 holders and is intended for use by machinists and tooling specialists working on metal fabrication and production drilling operations.

This insert is suited for drilling steel, stainless steel, cast iron, super-alloys, titanium, and hard materials, covering ISO workpiece material codes P, M, K, S, and H. It fits typical production environments where consistent hole geometry and insert interchangeability are priorities. The T-A Series platform is a modular system that allows insert changes without removing the holder from the machine, making it a practical choice for high-volume drilling cells and job shops alike.
