Sandvik Coromant 7100988 Milling Insert Grade 1130 Carbide

Product Description

The SANDVIK COROMANT 7100988 is a round, solid carbide milling insert in grade 1130, designed for use in R300 series face and shoulder milling cutters. Coated with AlTiCrN via a PVD process, this single-sided insert delivers reliable wear resistance across a broad range of workpiece materials. It features a 0.5-inch inscribed circle, a thickness of 0.1563 inches (3.97 mm), and six cutting edges with a positive rake angle of 20 degrees and a rounded cutting edge style. The PM chip breaker geometry supports stable cutting across varying feed and depth conditions. This insert is installed and replaced by machinists and CNC tooling technicians in production and job-shop environments.

This insert is suited for milling operations on steel, stainless steel, non-ferrous metals, superalloys, titanium, and hard materials, covering ISO material codes P, M, N, S, and H. It fits RA300 cutter bodies and is used in both roughing and semi-finishing applications where a round insert profile is specified. The neutral hand orientation makes it compatible with standard R300 tooling setups. ANSI and ISO catalog designation is R300-1340M-PM 1130, insert size code 1340.

Compatibility

Compatible with R300 series and RA300 cutter bodies as specified by the manufacturer. ANSI and ISO designation R300-1340M-PM 1130 confirms fitment. Insert size code is 1340. Verify cutter body seat dimensions and insert size code before installation.

Installation Notes

Installation is performed by qualified machinists or CNC tooling technicians. Power down and lock out the machine spindle completely before changing inserts. Use the correct torx or hex key for the clamping screw and follow the cutter body manufacturer's specified seating and torque procedure. Inspect the insert pocket and clamping screw for wear or damage before installing a new insert.
