Ruko Rotary burr KUD — Solid carbide ball-head cutter, KVZ 4

The Ruko Rotary burr KUD is a solid-carbide, ball-headed rotary cutter designed for precise shaping, deburring and contour work in professional workshop and production settings

• Solid carbide ball-shaped head
• Shank Ø 6 mm, total length 47 mm
• Cross-cut tooth pattern KVZ 4
• DIN 8033 Form D compatibility

Accurate finishing thanks to a ball-shaped head and cross-cut geometry

The solid carbide construction and ball-shaped head provide consistent rigidity and a predictable cutting edge, which benefits processes that require fine surface control. The cross-cut (KVZ 4) tooth pattern reduces the tendency to clog while producing a smoother surface than coarse single-cut profiles; this means fewer rework cycles and a cleaner finish on complex contours. For workshops aiming to maintain throughput without sacrificing surface quality, this geometry supports efficient removal of material with minimal vibration and stable cutting behaviour.

Stable handling and improved tool life from a compact shank design

A Shank Ø 6 mm combined with an overall length of 47 mm gives the tool a compact, vibration-resistant footprint in standard collets, increasing dimensional stability during high-speed rotation. The Head Ø 8 mm and Head length 7.2 mm allow the cutter to access tight radii and internal contours while keeping the clamping length short. The carbide composition offers wear resistance that translates into predictable tool life and repeatable results across production runs, reducing the frequency of tool changes and maintaining process reliability.

Standards-based compatibility for seamless workshop integration

Built to DIN 8033 (Form D, KUD), the design ensures straightforward replacement within existing fleets of rotary burrs and compatibility with common tool holders used in metalworking shops. The compact dimensions and standardised form factor facilitate quick tool changes and easy stocking. The result is a pragmatic combination of precision geometry and universal fitting that supports both specialised finishing tasks and general workshop use, simplifying procurement and tool management for production planners.

FAQ

What shank size does the cutter use?
The cutter features a 6 mm shank diameter, making the Ruko rotary burr KUD suitable for standard 6 mm collets and quick-change holders.

How does the KVZ 4 cross-cut affect the finish?
The KVZ 4 cross-cut pattern on this Ruko rotary burr produces finer chips and reduces clogging compared with single-cut profiles, resulting in a smoother surface after finishing.

Is the tool compatible with standard tool holders?
Yes, the KUD form follows DIN 8033 specifications and the shank dimensions ensure compatibility with common workshop collets and holders.

What dimensions define the cutting head?
The cutting head has an 8 mm diameter and a 7.2 mm head length, allowing access to small radii and detailed contour work.

How does solid carbide benefit day-to-day use?
Solid carbide construction provides high rigidity and wear resistance for consistent cutting performance and predictable tool life across repetitive operations.
