Ingersoll Cutting Tools 6126858 Trigon Milling Insert

Product Description

The INGERSOLL CUTTING TOOLS 6126858 is a UNEU1307R-M solid carbide milling insert designed for demanding material removal in cast iron and hard material applications. The insert features a trigon (80-degree included angle) shape with a double-sided, negative rake geometry that provides six usable cutting edges per insert. A PVD-applied TiAlN and TiN coating improves wear resistance and thermal stability at the cutting zone. At 0.2756 inches thick and 0.5118 inches inscribed circle diameter, this is a size 13 insert with a micrograin carbide substrate that supports consistent edge integrity under high-feed conditions. It is installed and used by machinists and tool-and-die professionals in CNC milling operations.

This insert is suited for milling applications where cast iron and hard workpiece materials are the primary focus. The right-hand cutting orientation, chamfered cutting edge style, and M-style chip breaker geometry make it appropriate for face milling and shoulder milling setups requiring controlled chip flow. The maximum depth of cut is 0.0780 inches. Compatible cutter series include 1DG1P, 4W2A, and DG6P, making it a practical choice for shops already running those tool bodies. The insert is held in place by a screw-clamp method standard to the UNEU insert style.

Installation Notes

Installation is performed by qualified machinists or tooling technicians. Disengage and lock out the spindle before replacing inserts. Use the appropriate Torx or hex key to seat the clamping screw to the tool body manufacturer's specified method - do not overtighten or undertighten. Verify insert seating and orientation before resuming cutting operations.
