Allied Machine 131T-.796 Spade Drill Insert 51/64 in Hss Tin

Product Description

The ALLIED MACHINE AND ENGINEERING 131T-.796 is a spade drill insert designed for high-production drilling applications in metalworking environments. This insert measures 51/64 inches in diameter and is manufactured from M4 grade high speed steel, offering strong wear resistance at elevated cutting temperatures. A PVD-applied TiN coating reduces friction and extends tool life between regrinds. The 132-degree point angle is suited for general-purpose drilling into a range of workpiece materials. Machinists and toolroom technicians install this insert into a compatible T-A series spade drill holder, replacing it when cutting edge wear affects hole quality or dimensional accuracy.

This insert is rated for use in steel, cast iron, and non-ferrous metal workpieces, covering ISO material codes P, K, and N. It fits Seat Size 1 T-A series spade drill holders and is appropriate for CNC machining centers, radial arm drills, and manual drill presses where spade drilling is specified. It is a common choice in job shops, production machining operations, and maintenance environments handling a broad mix of workpiece materials.
