Allied 151T-0024-SP Spade Drill Insert 3/4 in Cobalt Tin

Product Description

The ALLIED MACHINE AND ENGINEERING 151T-0024-SP is a spade drill insert designed for high-performance hole-making in demanding machining environments. This insert measures 3/4 inch in diameter and features a 90-degree point angle, making it well-suited for flat-bottomed entry and through-hole drilling applications. Constructed from cobalt high-speed steel and finished with a Physical Vapor Deposition (PVD) titanium nitride (TiN) coating, the 151T-0024-SP delivers improved wear resistance and extended tool life. At 0.1563 inches in thickness, this insert seats into a Seat Size 1 holder body. It is installed and used by machinists, toolroom technicians, and CNC operators in production and job-shop environments.

The 151T-0024-SP is part of the T-A Series spade drill system and is engineered for use in steel, stainless steel, cast iron, super-alloys, and titanium workpieces. These material classifications correspond to ISO work material codes P, M, K, and S. Typical applications include general-purpose drilling in production machining, component manufacturing, and maintenance operations where a replaceable insert system reduces tooling cost and downtime compared to solid-body drills.

Installation Notes

Installation should be performed by a qualified machinist or toolroom technician with the machine spindle stopped and the machine fully powered down before insert replacement. Ensure the holder body seat is clean and free of chips or debris before seating the insert. Use the appropriate insert screw and torque method specified by the holder body manufacturer. Verify insert seating is secure before resuming machining operations.
