RBF Rotary Burr 12 mm — Solid Carbide, KVZ 4 (RUKO)

The RBF rotary burr is a solid-carbide cutting tool in round-arch form (Form F) per DIN 8033, intended for precise profiling, deburring and contouring tasks where consistent cutting geometry is required

• Solid carbide construction
• Cross-cut tooth pattern KVZ 4
• 12 mm head, 25 mm cutting length

Faster, more reliable stock removal for production workflows

The solid carbide design of this rotary burr delivers high rigidity and improved wear resistance compared with unalloyed tool steels, which translates into longer intervals between tool changes and more predictable process times. The cross-cut KVZ 4 tooth pattern creates smaller chips and a smoother cutting action, reducing vibrational peaks and the risk of chatter during finishing passes. Compliance with DIN 8033 (Form F / RBF) provides a clear geometric reference for process planning and fixture alignment, helping to integrate the cutter into existing machining cycles with little guesswork.

Consistent results with easy tool accommodation

With a 12 mm head diameter and 25 mm cutting length, the burr provides a compact cutting envelope that benefits fine contouring and internal profiling. The 6 mm shank fits common collets and holders, enabling straightforward mounting in rotary tools and spindle systems that accept 6 mm tooling. Because the component geometry is standardised, cutter behaviour becomes repeatable across batches, simplifying quality assurance and minimizing rework—in short, consistent part-to-part surface quality with reduced inspection effort.

Practical handling and workshop compatibility

The tool’s overall length of 65 mm and standard shank specification make it easy to store, identify and fit into existing tool sets. The round-arch (RBF) form offers predictable access in recessed areas and along curved contours, while the cross-cut geometry helps maintain surface finish during directional changes. Supplied individually, the burr is suitable for workshops seeking a reliable single-item replacement or integration into assortments. For specific machining scenarios or clamping questions, Metav Werkzeuge’s consultants are available to advise on optimal holder selection and operating ranges.
