RCMT 1204FN KS15F Tungaloy indexable milling insert – round 12 mm, carbide

The RCMT1204FN-NAJ KS15F Tungaloy indexable insert is designed for versatile milling tasks, offering reliable chip control and edge stability for face, shoulder, slot, high-feed and contour milling.

Compatible with Tungaloy milling systems Round 12 mm insert for flexible contact Carbide grade KS15F for balanced performance 7° relief angle and cylindrical bore with countersink

Productive, predictable milling performance for series production

The insert is manufactured from carbide, optimised for milling operations where repeatable results and tool life are decisive. The KS15F grade combines wear resistance and toughness to maintain the cutting edge under varied loads, which reduces tool-change frequency and increases uptime. Using a round geometry with a NAJ chipbreaker supports controlled chip formation in interrupted and continuous cuts, lowering the risk of workpiece marks and improving surface finish. This results in tangible productivity gains for batch and continuous machining.

Secure clamping and precise seating for consistent cutting geometry

A reliable clamping interface is essential for dimensional accuracy. The round insert features a cylindrical bore with a single-side countersink (40°–60°) that ensures correct seating and stable fixation on compatible milling bodies. The specified 4.76 mm thickness and 12 mm diameter create a low-profile contact that helps maintain concentricity and reduces vibration. Correct matching of insert seat, geometry and milling body leads to repeatable toolpaths and predictable tool life across a production run.

Broad application range with simplified process selection

This insert supports face, shoulder, slot, high-feed and contour milling depending on the chosen cutter family, making it suitable for workshops that require flexible tooling options. The 7° relief angle enables effective shear engagement while preserving cutting-edge stability, especially in tough or variable materials. Thanks to the round form, fewer inventory variants are needed to cover multiple milling approaches, simplifying tooling management and lowering logistical complexity.

Practical advantages and handling notes for process engineers

The NAJ chipbreaker is tuned to promote short, controllable chips under a variety of feeds and depths of cut, which eases chip evacuation and reduces downtime for clearing. The insert is intended for use in properly matched Tungaloy milling systems; seat geometry and clamping torque must conform to the tool manufacturer's guidelines to achieve rated performance and safety. Stored and handled correctly, the carbide body resists typical workshop impacts and preserves the coated or uncoated cutting edges for longer operation.

FAQ

What operations is this insert suitable for?
The RCMT1204FN-NAJ KS15F Tungaloy indexable insert is designed for face, shoulder, slot, high-feed and contour milling when used in a compatible Tungaloy milling body.

Which material is the insert made from and what does KS15F mean?
The insert is made from carbide and the KS15F designation denotes a Tungaloy grade engineered for a balance of wear resistance, toughness and cutting-edge stability suitable for general milling.

How does the NAJ chipbreaker affect machining?
The NAJ chipbreaker promotes controlled chip formation and evacuation, improving process reliability and surface finish for the intended milling applications.

What dimensions and clamping features should be noted?
Key dimensions are 12 mm diameter and 4.76 mm thickness; the insert has a cylindrical bore with a single-side countersink (40°–60°) that requires the correct mating seat and clamping screw for secure fixation.

Can this insert be used with non-Tungaloy milling bodies?
Performance depends on exact seat geometry and clamping method; the insert is intended for Tungaloy milling systems, and compatible bodies must match the specified insert seat and geometry for safe and repeatable use.
