Sandvik Coromant 7100961 Ball Nose Milling Insert RA216

Product Description

The SANDVIK COROMANT 7100961 is a solid carbide ball nose milling insert in the RA216 series, designed for use in rotating milling cutters across a wide range of machining applications. Manufactured to grade 1130 with a PVD-applied AlTiCrN coating, this insert delivers thermal and wear resistance suited to demanding cutting conditions. It features a positive rake angle, a rounded cutting edge style, and a right-hand orientation. The insert measures 3.97 mm (0.1563 inches) thick with a convex radius of 0.3740 inches and a length of 0.6690 inches. It is held in place by a screw-type clamping method and is intended for installation by machining professionals and tooling technicians.

This insert is suited for milling steel, stainless steel, non-ferrous metals, superalloys, titanium, and hard materials. It carries material grade designations P30, M15, and N15, covering a broad spectrum of workpiece material groups per ISO classification. The RA216 series is commonly applied in ball nose end milling operations for contour milling, die and mold work, and finish passes on complex geometries in both production and job shop environments. With two cutting edges per insert and a single-sided design, this insert is a direct replacement component for RA216-compatible cutter bodies.

Installation Notes

Installation should be performed by a qualified machining technician or toolroom professional. Power down and lock out the machine spindle before changing inserts. Use the correct torx or hex key specified for the cutter body to tighten the clamping screw to the cutter manufacturer's seating specification. Inspect the insert pocket and clamping screw for wear or damage before seating a new insert.
