RFEN 2004M0 UX30 indexable insert for milling by Tungaloy — round 20 mm, 25° clearance angle

RFEN 2004M0 UX30 is a round indexable insert designed for milling applications where low cutting forces and reliable chip formation are priorities

• Uncoated carbide grade UX30
• Sharp cutting edge for low cutting forces
• Round 20 mm insert, 4.76 mm thickness
• 25° clearance angle, no chipbreaker

Greater productivity through a sharp-edged carbide grade

The UX30 grade is an uncoated carbide developed for operations that require a sharp cutting edge and controlled chip flow. In practical terms, the geometry of this insert reduces the energy required per cut, which directly translates into lower spindle loads and improved tool life under many cutting conditions. The combination of a fine edge and carbide substrate supports consistent surface finish during planing, shoulder, slot and contour milling when used within the appropriate tool family. For users seeking economical, repeatable performance, this insert offers a straightforward way to reduce cycle time while preserving edge stability.

Secure system compatibility and straightforward replacement

Designed for Tungaloy milling systems, the insert requires that the insert seat, geometry and cutter body match correctly to ensure clamping reliability. The RFEN2004M0 format is an indexable insert, meaning it can be rotated or replaced without regrinding, which reduces downtime and lowers overall tooling cost per part. Correct mechanical fit and the use of the specified clamping screw and backing washer (where applicable) ensure stable seating and repeatable positioning after indexation. This approach supports a production-oriented workflow by simplifying maintenance and ensuring that each indexing operation restores the original cutting geometry.

Clear specifications for predictable machining results

Key dimensions and the lack of a chipbreaker define the insert’s best uses: the round 20 mm profile with 4.76 mm thickness and a 25° clearance angle produces a low contact area and reduces cutting forces in thin depths of cut. The absence of a chipbreaker indicates behaviour suited to controlled chip evacuation strategies or specific workpiece materials where free-flowing chips are acceptable. The zero corner radius supports sharp-edge engagement and is beneficial where minimal radial cutting force is desired. When integrating this insert, verify compatibility with the chosen cutter body and select cutting parameters that reflect the sharp-edge geometry to achieve the intended balance of surface finish and productivity.

FAQ

What workpiece materials is this insert suitable for? The RFEN2004M0 UX30 indexable insert is specified as an uncoated carbide grade aimed at applications where low cutting forces and good chip formation are required; suitability depends on the chosen cutting data and the workpiece material.

Does the insert require a chipbreaker for safe operation? This RFEN2004M0 UX30 insert is supplied without a chipbreaker, so chip control must be managed by cutting parameters, coolant strategy or the cutter body design.

How does the round shape affect milling performance? The round shape and zero corner radius of the RFEN2004M0 UX30 allow for smooth contouring and consistent engagement, reducing peak radial loads during interrupted cuts.

Is the insert reversible or indexable? The RFEN2004M0 UX30 is an indexable insert; it can be rotated or replaced to restore the cutting edge without regrinding, provided the insert seat and clamping system match the Tungaloy milling body.

What are the critical checks before mounting the insert? Ensure mechanical compatibility between the insert, cutter body and clamping screw; check that the seat geometry matches RFEN2004M0 and that the cutter is specified for a 20 mm round insert with 4.76 mm thickness.
