Ingersoll Cutting Tools 5811265 SDMT12R Carbide Drill Insert

Product Description

The INGERSOLL CUTTING TOOLS 5811265 is a square carbide indexable drill insert in the SDMT12 series, designed for use in indexable drill bodies used in metal cutting operations. Coated with TiAlN via a PVD process, this insert delivers thermal resistance and wear performance across a range of workpiece materials. The insert features a 0.5-inch inscribed circle, 0.236-inch thickness, and a 0.031-inch corner radius with a positive rake geometry and chipbreaker designation R. With four cutting edges per insert, it offers multiple index positions before replacement, reducing tooling cost per hole.

This insert is suited for drilling operations in steel, cast iron, stainless steel, superalloys, titanium, and hard materials, covering ISO material grades P, M, K, S, and H. The SDMT120608R geometry and 90-degree included angle make it appropriate for high-feed indexable drill applications in both production and job-shop environments. It is compatible with drill style 5J1H. Licensed machinists, tool-and-die technicians, and CNC operators working in ferrous and nonferrous metal removal applications are the primary installers and users of this insert.

Installation Notes

Indexable drill inserts are seated and torqued into the drill body pocket by machinists or CNC setup technicians following the drill body manufacturer's specified clamping procedure. Power down and lock out the machine spindle before indexing or replacing inserts. Use the correct torx or hex key driver recommended by the drill body manufacturer to avoid stripping the clamping screw. Inspect the pocket seat and clamping screw for wear or debris before seating a new insert.
