Allied Machine 131T-0026 Spade Drill Insert 13/16 in Hss Tin

Product Description

The ALLIED MACHINE AND ENGINEERING 131T-0026 is a T-A series spade drill insert designed for high-productivity drilling in steel, cast iron, and non-ferrous metals. Measuring 13/16 inches in diameter with a 0.1563-inch thickness, this insert features a 132-degree point angle that promotes accurate entry and efficient chip evacuation. Manufactured from M4 grade high speed steel and finished with a PVD-applied TiN (titanium nitride) coating, the 131T-0026 delivers extended tool life under demanding production conditions. Machinists and tool-room technicians working with T-A series spade drill holders will find this a direct-fit replacement or production-run insert.

This insert is suited for drilling operations in general machining environments, including job shops and production floors handling steel components, cast iron workpieces, and non-ferrous metal parts. Its Seat Size 1 designation corresponds to the T-A series holder system, making it appropriate for a range of light to medium drilling applications where consistent hole quality and tool longevity are priorities. It is typically installed by machinists and CNC operators working with compatible T-A series spade drill bodies.

Installation Notes

Insert replacement should be performed by a qualified machinist with the machine fully powered down and the spindle locked. Use the appropriate torque wrench and insert screw per the holder manufacturer's seating guidelines to avoid pocket damage. Inspect the holder seat for wear or debris before seating a new insert, as a contaminated seat will affect runout and hole quality. Never force the insert into the pocket or substitute fasteners not specified for the holder.
