Allied 151A-0026-SS Spade Drill Insert 13/16 in Cobalt Tialn

Product Description

The ALLIED MACHINE AND ENGINEERING 151A-0026-SS is a cobalt spade drill insert from the T-A series, designed for high-performance drilling in demanding metalworking applications. At 13/16 inches in diameter with a Seat Size 1 configuration and a 150-degree point angle, this insert delivers consistent penetration and chip control across a range of ferrous and non-ferrous materials. The PVD-applied TiAlN coating provides heat resistance and wear protection at elevated cutting speeds, extending tool life in production environments. This insert is installed and replaced by machinists, tool-and-die technicians, and CNC operators working in industrial and job-shop settings.

The 151A-0026-SS is suited for drilling into steel, stainless steel, cast iron, super-alloys, and titanium. Its T-A series geometry is optimized for through-hole and blind-hole operations on vertical machining centers, horizontal mills, and CNC lathes equipped with compatible T-A series spade drill holders. The 150-degree point angle reduces thrust and is well-suited for harder workpiece materials where standard 118-degree or 135-degree geometry would wear prematurely. Packaging is sold individually; the minimum order quantity is 2 units.

Key Features

• 13/16 inch diameter cobalt insert for the T-A spade drill system
• 150-degree point angle reduces axial thrust in hard and abrasive materials
• PVD TiAlN coating improves heat resistance and extends tool life at high cutting speeds
• Compatible workpiece materials include steel, stainless steel, cast iron, super-alloys, and titanium
• Seat Size 1 ensures proper seating and retention in matching T-A series spade drill bodies
• Thickness of 0.1563 inches provides consistent insert geometry for repeatable hole quality

Compatibility

Designed for use with T-A series spade drill holders accepting a Seat Size 1, 13/16 inch diameter insert. Primary workpiece material classifications supported are P (steel), M (stainless steel), K (cast iron), and S (super-alloys and titanium).

Installation Notes

Insert replacement should be performed by a qualified machinist or tooling technician with the machine powered down and all stored energy released before handling the drill body. Use the appropriate T-A series insert seating tool or torx key as specified by the holder manufacturer to secure the insert without over-torquing the retention screw. Inspect the holder pocket and seating surfaces for debris or damage before installing a new insert. Follow the machine shop safety protocols and manufacturer feed-and-speed guidelines for the specific workpiece material being drilled.
