Kennametal 1161986 RCMT215 KC730 Carbide Turning Insert

Product Description

The KENNAMETAL 1161986 is a solid carbide turning insert in RCMT215 geometry, PVD-coated with TiN for extended tool life on difficult workpiece materials. It features a round insert shape with a full radius, a 0.125 inch corner radius, and a 0.25 inch inscribed circle diameter. The KC730 grade is engineered for high wear resistance across steel, stainless steel, and cast iron applications, with a honed cutting edge style that reduces built-up edge and supports consistent surface finish. The insert carries a neutral hand designation and mounts via screw-on holding, making it compatible with standard RCMT-style toolholders used in CNC turning centers.

This insert is suited for turning, facing, and boring operations on steel (P), stainless steel (M), and cast iron (K) workpiece materials, as well as secondary use on superalloys and titanium (S). It is designed for medium machining chip breaker conditions, making it a practical choice for general-purpose production turning in both job shop and high-volume manufacturing environments. A maximum depth of cut of 0.049 inches is specified for the insert geometry. Licensed machinists and CNC operators typically specify this insert in applications requiring balanced wear resistance and toughness.

Key Features

• RCMT215 round insert shape with full radius and 0.125 inch corner radius for multi-directional cutting
• KC730 grade with PVD TiN coating delivers high wear resistance on steel and stainless steel
• Positive rake and positive side clearance (clearance code C) reduce cutting forces
• 4 usable cutting edges per insert for extended service life per unit
• Screw-on holding method with 0.1102 inch hole diameter for secure toolholder engagement
• Meets ANSI and ISO standards; ANSI code RCMT215, ISO code RCMT060200

Compatibility

Designed as an OEM-style screw-on replacement insert for RCMT-style toolholders conforming to ANSI RCMT215 and ISO RCMT060200 specifications. Intended for use on steel, stainless steel, and cast iron workpieces; secondary compatibility includes superalloys and titanium.

Installation Notes

This insert is installed by licensed machinists or CNC tooling technicians using the appropriate RCMT screw-on toolholder. Power down and lock out the machine before indexing or replacing inserts. Use the manufacturer-specified torque driver for the mounting screw to ensure proper seating without cracking the carbide body. Verify insert orientation and edge condition before resuming cuts.
