Allied Machine 151H-0030-NP Spade Drill Insert 15/16 in Cobalt

Product Description

The ALLIED MACHINE AND ENGINEERING 151H-0030-NP is a cobalt spade drill insert engineered for high-performance hole-making in demanding machining applications. Measuring 15/16 inches in diameter with a 132-degree point angle, this insert is built to the T-A series seat size 1 standard and features an AM200 PVD coating for extended tool life and improved wear resistance. At 0.1563 inches thick, it delivers the dimensional consistency required for precision drilling operations. Machinists and tool-crib professionals working in production or job-shop environments will find this insert suited for aggressive metal removal in a range of workpiece materials.

This insert is designed for use in steel, stainless steel, cast iron, super-alloys, and titanium workpieces, covering ISO material groups P, M, K, and S. It fits T-A series spade drill holders with seat size 1 bodies, making it a direct replacement insert for applications where cobalt substrate and AM200 PVD coating are specified for hard or abrasive materials. Typical use cases include through-hole and blind-hole drilling on CNC machining centers, lathes, and drill presses in industrial manufacturing environments.

Key Features

• 15/16 inch diameter with 132-degree point angle for consistent chip formation
• Cobalt substrate provides added toughness and heat resistance over standard HSS inserts
• AM200 PVD coating extends wear life in steel, stainless steel, cast iron, super-alloys, and titanium
• T-A series seat size 1 design for direct fit into compatible spade drill holders
• 0.1563 inch thickness maintains insert stability and seating integrity under high feed rates

Compatibility

Designed for use with T-A series spade drill holders accepting seat size 1 inserts. Compatible workpiece materials include steel, stainless steel, cast iron, super-alloys, and titanium (ISO material codes P, M, K, and S).

Installation Notes

Installation should be performed by a qualified machinist or tooling technician. Ensure the spade drill holder is fully secured and the machine spindle is powered down and locked out before inserting or replacing the spade drill insert. Seat the insert fully against the holder pocket and confirm the clamping screw is torqued according to the holder manufacturer specifications. Inspect the insert seat for chips or debris before installation to prevent seating errors that can affect hole quality or cause insert breakage.
