PFERD carbide rotary burr KUD — ball head, 4 mm, 6 mm shank

PFERD carbide rotary burr in KUD form for precise shaping and finishing tasks in toolrooms and workshops, particularly where compact, high-precision burrs are required

• Solid carbide construction for long life
• Shank Ø 6 mm for standard collet systems
• Ball-shaped head Ø 4 mm for contour work
• DIN 8033 KUD form for standard compliance

Durable carbide body for precise material shaping

The carbide composition ensures a high degree of durability and edge retention under frequent use. With a head diameter of 4 mm and a head length of 3 mm, the tool enables fine contouring and detail work where predictable results are required. The compact design minimises vibration and supports consistent cutting behaviour, which contributes to a stable surface finish and reduced rework in production and repair operations.

Secure fit and handling with a 6 mm shank

A 6 mm shank offers compatibility with common collet holders and rotary tool chucks found in many workshops. The overall length 45 mm provides reach without compromising stability, allowing controlled access to small or recessed areas. The standard shank diameter supports repeatable clamping, so runout is minimised and tool life is extended through correct seating and balanced rotation.

3 PLUS tooth pattern for efficient cutting and finish

The 3 PLUS tooth pattern is designed to balance material removal rate and surface quality. This tooth geometry helps maintain a steady cut while avoiding rapid clogging in many general-purpose tasks, which results in fewer interruptions for cleaning and a smoother workflow. The pattern is suitable for operations where a consistent cutting rhythm and a fine finish are priorities.

Conformance to DIN 8033 KUD for interchangeability

Manufactured to DIN 8033 in the KUD form, this burr follows an established standard so replacements and tool selection are straightforward. Conformity with the standard simplifies procurement and tool inventory management, allowing technicians to specify compatible burrs with confidence and to plan maintenance cycles based on predictable tool behaviour.

Practical workshop advantages and versatile use

The ball-shaped head (Kugelform) provides access for rounding, deburring, profiling and fine sculpting of contours, making it a practical choice for detail work in metalworking and craft applications. The robust carbide composition and standardised dimensions reduce the frequency of tool changes and help maintain production continuity, while the compact geometry supports ergonomic handling during manual or machine-assisted operations.
