Kennametal 5413747 Round Turning Insert KC725M 12mm Ic Rodeka

Product Description

The KENNAMETAL 5413747 is a solid carbide round turning insert in the Rodeka series, designed for external and internal turning operations on CNC lathes and turning centers. Carrying the KC725M grade designation, this insert features a PVD-applied TiAlN and TiN multilayer coating that extends tool life in demanding cutting conditions. The round (RNPJ) insert geometry provides a 360-degree included angle with a 12 mm (0.4724 inches) inscribed circle, a negative rake configuration, and a 0-degree relief angle. Insert holding is via screw clamp. Eight usable cutting edges per insert contribute to a low cost-per-edge profile, making this insert a practical choice for production turning environments.

The 5413747 is suited for turning steel (P20, P30), stainless and heat-resistant alloys (M15, M25), and high-temperature superalloys (S-grade materials). The PVD TiAlN and TiN coating resists heat buildup and adhesive wear when cutting these primary workpiece material groups. Typical applications include finish and semi-finish turning passes on CNC turning centers in both job shop and production manufacturing settings. The Rodeka series geometry, paired with the J chip breaker designation, handles moderate-to-interrupted cuts on ductile workpiece materials. Machinists and tooling technicians handling general-purpose turning across steel and stainless families will find the KC725M grade well-matched to these conditions.

Key Features

• Round insert shape (RNPJ) with 360-degree included angle and 8 cutting edges per insert
• KC725M carbide grade with PVD-applied TiAlN and TiN multilayer coating for thermal and wear resistance
• 12 mm (0.4724 inches) inscribed circle, insert size code 1204M0
• Negative rake geometry with 0-degree relief angle for stable edge engagement
• J chip breaker configuration suited to moderate cutting conditions on steel and stainless
• Screw-clamp insert holding method compatible with standard Rodeka toolholders

Compatibility

Designed for use with Rodeka-series screw-clamp toolholders accepting RNPJ 1204M0 round inserts. Rated for primary workpiece material groups P (carbon and alloy steel), M (stainless steel), and S (high-temperature alloys and titanium) per ISO material classification.

Installation Notes

Installation should be performed by a qualified machinist or tooling technician. Power down and lock out the machine spindle before indexing or replacing inserts. Use the correct torx or hex key to the toolholder manufacturer's specified seating procedure when securing the clamp screw — do not overtighten, as this can fracture the insert. Inspect the insert pocket and clamp seat for chips or debris before seating a new edge.
