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

Product Description

The ALLIED MACHINE AND ENGINEERING 151A-0030 is a cobalt 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 a TiAlN (titanium aluminum nitride) PVD coating that extends tool life by resisting heat and wear at the cutting edge. At 15/16 inch in diameter with a Seat Size 1 designation, it mounts into compatible T-A series spade drill bodies and holders. Machinists and tooling specialists working in production and job-shop environments will find this insert suited for aggressive, consistent drilling performance across a range of workpiece materials.

This insert is engineered for use on steel, stainless steel, cast iron, super-alloys, and titanium workpieces, covering ISO material groups P, M, K, and S. It is appropriate for CNC machining centers, lathes with live tooling, and dedicated drill presses where T-A series spade drill holders are in use. Typical applications include through-hole and blind-hole drilling in structural components, flanges, housings, and similar machined parts requiring consistent diameter control and a clean exit geometry.

Installation Notes

Installation should be performed by a qualified machinist or tooling technician. Ensure the drill body and insert seating surfaces are clean and free of chips or debris before securing the insert. Follow the tool body manufacturer torque guidelines for the insert clamping screw to prevent insert movement or damage. Always power down and lock out the machine spindle before changing or inspecting spade drill inserts.
