Kennametal 1776013 Round Milling Insert KC725M Solid Carbide

Product Description

The KENNAMETAL 1776013 is a round solid carbide milling insert in the RDHX1604M0SGN series, designed for high-performance indexable milling applications. Manufactured to the KC725M grade, it carries a TiAlN coating applied via PVD process, providing thermal resistance and wear protection during demanding cuts. The insert features a 0.6299-inch inscribed circle, a thickness of 0.1875 inches, and delivers 4 usable cutting edges per insert. A 15-degree relief angle and positive rake geometry reduce cutting forces and help manage heat at the edge. The chamfered and honed cutting edge style adds stability and edge strength across a range of workpiece materials. Licensed machinists and CNC tooling professionals typically specify this insert for precision milling operations.

This insert is suited for milling steel, stainless steel, superalloys, and titanium in both roughing and semi-finishing applications. The GN chip breaker geometry supports effective chip evacuation across these material groups. The insert is held by screw clamping, making it compatible with the KDM-16 cutter series. It is designed for single-sided use with a neutral hand orientation, allowing consistent setup in fixed-pocket toolholders. Applications span general machining environments where tool life, edge consistency, and material compatibility across P, M, and S ISO workpiece categories are priorities.

Key Features

• Round RDHX insert shape with 360-degree included angle and 4 cutting edges per insert
• KC725M solid carbide grade with TiAlN PVD coating for extended tool life in steel and superalloy milling
• Positive rake geometry with 15-degree relief angle reduces cutting forces
• Chamfered and honed cutting edge style improves edge toughness and surface finish
• GN chip breaker promotes chip control in steel, stainless steel, and titanium
• Screw-held, single-sided, neutral-hand design for repeatable indexing in KDM-16 compatible toolholders

Compatibility

Designed for use with the KDM-16 cutter series. Conforms to ANSI and ISO standards under code RDHX1604M0SGN. Suited for workpiece materials classified under ISO material codes P (steel), M (stainless steel), and S (superalloys and titanium), corresponding to carbide material grades C5, C6, and C7.

Installation Notes

Installation is performed by qualified machinists or CNC tooling technicians. The machine spindle must be fully stopped and the toolholder secured in a safe position before indexing or replacing inserts. Use the appropriate torx or hex key to seat the clamping screw to the toolholder manufacturer's specified torque — do not overtighten, as this can fracture the insert. Inspect the insert pocket for wear or debris before seating each new insert to ensure proper contact and edge registration.
