RCMT1606FN-NAJ KS15F Tungaloy indexable milling insert – round 16 mm, NAJ chipbreaker for milling

RCMT1606FN-NAJ KS15F Tungaloy indexable milling insert designed for milling operations where the insert seat, geometry and cutter body are matched for optimal performance

• KS15F grade for balanced wear resistance
• Round 16 mm form with 6.35 mm thickness
• Cylindrical hole with 40°–60° countersink
• Suitable for face, shoulder and slot milling

Reliable cutting behaviour for diverse milling tasks

The KS15F insert grade, integrated into a cemented carbide substrate, offers a deliberate compromise between hardness and toughness that supports repeatable machining across a variety of workpiece materials. The round geometry provides multiple cutting edges, which increases tool life in interrupted and continuous cuts while the NAJ chipbreaker controls chip formation for stable evacuation. This results in more consistent surface finishes and reduced downtime due to fewer insert changes.

System compatibility and practical assembly benefits

Designed specifically for Tungaloy milling systems, the insert requires a matching insert seat and cutter body; the system-based design ensures secure clamping and correct seating. The central cylindrical hole with a single-sided countersink (40°–60°) permits reliable locating and clamping, while the 7° relief helps to reduce rubbing on the flank during engagement. These features combine to decrease vibration and promote predictable cutting forces, which supports higher productivity in shop-floor environments.

Clear application advantages and process optimisation

The geometry and grade are suitable for face, shoulder, slot, high-feed and contour milling depending on the assigned cutter family. The round form and sturdy substrate permit occasional heavy engagement and interrupted cuts, providing economic performance in mixed-series production. The insert's dimensions (16 mm diameter, 6.35 mm thickness) simplify inventory management by aligning with common cutter bodies and permit quick replacement to restore cutting capability.

Interpreting technical terms and achieving consistent results

For customers less familiar with carbide grades and chipbreaker nomenclature: KS15F denotes a Tungaloy-specific grade engineered to combine wear resistance with edge stability; NAJ refers to a chipbreaker geometry tailored to produce short, controllable chips in a range of feeds and depths. The cemented carbide construction is chosen for its hardness and heat resistance, making it suitable for extended milling cycles. Matching insert and cutter specifications is essential for the intended performance.

FAQ

What materials can this insert machine effectively?
The RCMT1606FN-NAJ KS15F insert is intended for a broad range of milling tasks; the KS15F grade and cemented carbide body provide balanced wear resistance and toughness suitable for many common engineering materials.

How does the NAJ chipbreaker affect machining?
The NAJ chipbreaker produces short, controlled chips and improves evacuation during milling, which helps maintain consistent cutting forces and surface quality when using the RCMT1606FN-NAJ KS15F insert.

Is the insert compatible with non-Tungaloy cutter bodies?
The insert must be used in cutter bodies and seats that are technically compatible; correct seating and clamping are required to achieve the designed performance of the RCMT1606FN-NAJ KS15F Tungaloy indexable milling insert.

How many cutting edges are available on this round insert?
The round form of the insert provides multiple effective cutting edges; actual usable edges depend on the specific cutter design and wear patterns observed during operation.

What are the locating and clamping features of the insert?
The insert includes a cylindrical hole with a single-sided countersink (40°–60°) for reliable locating and clamping in compatible Tungaloy milling systems.
