Allied Machine 131A-0026 Spade Drill Insert 13/16 in Hss Tialn

Product Description

The ALLIED MACHINE AND ENGINEERING 131A-0026 is a spade drill insert designed for high-feed hole-making operations in a wide range of workpiece materials. Part of the T-A Series, this insert measures 13/16 inches in diameter and is machined from M4-grade High Speed Steel with a TiAlN PVD coating applied to extend cutting edge life and resist heat buildup at elevated cutting speeds. At 0.1563 inches thick and weighing 0.1 pounds, it seats into a Series 1 holder and delivers consistent, repeatable performance across production and maintenance drilling environments. The 132-degree point angle is suited for controlled entry and reduced thrust in common shop materials.

This insert is used in drilling applications across general manufacturing, fabrication, and machining environments where accurate through-holes or blind holes are required. The T-A Series platform is widely used in manual and CNC machining centers, drill presses, and lathes. Primary workpiece materials include Steel, Cast Iron, and Non-Ferrous Metals, corresponding to ISO material classifications P, K, and N. It is installed and changed by machinists and tool-room technicians as part of a modular drill body system.

Installation Notes

Insert replacement is performed by machinists or tool-room technicians as part of routine tool maintenance. Power down or lock out the spindle before handling any cutting insert. Seat the insert firmly against the holder pocket and verify proper clamping torque using the holder manufacturer's guidelines. Inspect the seat and clamping screw for wear or debris before reinstalling to ensure accurate positioning and safe operation.
