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

Product Description

The ALLIED MACHINE AND ENGINEERING 151T-0024-FB is a cobalt spade drill insert designed for high-performance hole-making operations in demanding materials. This Seat Size 1 insert measures 3/4 inch in diameter with a 180-degree point angle and a thickness of 0.1563 inches. It is manufactured from Super Cobalt grade material and features a Physical Vapor Deposition (PVD) Titanium Nitride (TiN) coating that improves surface hardness, reduces friction, and extends tool life in high-heat cutting environments. The 151T-0024-FB belongs to the T-A Series, a widely used replaceable-tip spade drill platform suited to production machining applications.

This insert is rated for use in steel, stainless steel, cast iron, superalloys, and titanium, covering ISO material codes P, M, K, and S. It is a fractional-inch system insert sized for T-A Series spade drill holders with a Seat Size 1 bore. Typical applications include production drilling in CNC machining centers, lathes with live tooling, and drill presses where consistent hole quality across multiple materials is required. Machinists and tooling specialists in metalworking, job shops, and manufacturing facilities are the primary users of this insert.

Key Features

• 3/4 inch diameter with 180-degree point angle for flat-bottomed entry geometry
• Super Cobalt grade substrate provides elevated red hardness and wear resistance versus standard HSS
• PVD TiN coating reduces built-up edge and extends cutting life in ferrous and exotic materials
• Seat Size 1 fits T-A Series spade drill holders for quick insert changeout without removing the holder from the machine
• Rated for steel, stainless steel, cast iron, superalloys, and titanium (ISO P, M, K, S)
• Fractional-inch system sizing for straightforward tool crib identification and ordering

Compatibility

Designed for use with T-A Series spade drill holders requiring a Seat Size 1, 3/4 inch diameter insert. Compatible workpiece materials include steel, stainless steel, cast iron, superalloys, and titanium as specified by the manufacturer.

Installation Notes

Insert installation and changeout should be performed by a qualified machinist or tooling technician with the machine in a full stop, locked-out, and tagged-out state per applicable machine safety procedures. Use the correct torque wrench and insert screw specified for the T-A Series holder to ensure proper seating and clamping force. Inspect the holder seat for chips or debris before installing a new insert. Running speeds and feeds should be set according to the manufacturer cutting data for the specific workpiece material and holder configuration.
