Allied Machine 151T-19 Spade Drill Insert 19mm Cobalt Tin

Product Description

The ALLIED MACHINE AND ENGINEERING 151T-19 is a spade drill insert designed for high-performance hole-making in demanding machining applications. Part of the T-A Series, this insert features a 132-degree point angle and is manufactured from T15 cobalt high-speed steel with a Physical Vapor Deposition (PVD) titanium nitride (TiN) coating. The TiN coating improves surface hardness and wear resistance, extending tool life in production environments. At 19 mm in diameter with a Seat Size 1 designation, it mounts into compatible T-A Series spade drill holders. Installation and operation are handled by machinists and tooling technicians in CNC and conventional drilling setups.

This insert is suited for drilling operations in steel, stainless steel, cast iron, super-alloys, and titanium workpieces, covering ISO material classifications P, M, K, and S. Typical applications include production drilling in job shops, aerospace, oil and gas, and heavy manufacturing environments where consistent hole geometry and tool life are priorities. The 132-degree point angle provides a balance between cutting efficiency and edge stability across these material groups.
