PFERD rotary burr, 4 mm ball head, HSS, 6 mm shank

The PFERD rotary burr KUD is a ball‑nose rotary cutter in high‑speed steel, designed for precision deburring, contouring and fine shaping in metalworking and toolroom applications.

• High‑speed steel construction for abrasive tasks
• Ball head Ø 4 mm for precise contour finishing
• Shank Ø 6 mm for secure toolholding in common collets
• Compliant with DIN 8033 Form F

Accurate contour finishing for detailed work

The ball‑nose geometry delivers tight radii and smooth transitions when shaping internal contours or edge profiles. The 4 mm ball head provides controlled material removal, making the tool suitable for finishing small cavities and fillets where dimensional tolerance matters. Thanks to the type 3 tooth pattern, the cutter balances stock removal and surface quality, reducing the need for subsequent manual rework. This combination of shape and cut pattern supports predictable machining times and repeatable results in series production and one‑off tasks alike.

Secure clamping and compatibility with standard toolholders

With a 6 mm shank, the burr fits standard collets and small die grinders commonly used in workshops and industrial cells. The compact overall length of 55 mm ensures good accessibility in confined fixtures while maintaining a safe engagement length. Conformity with DIN 8033 (Form F geometry) simplifies tool selection for systems that reference the standard, enabling straightforward integration into existing tool lists and documentation. The result is reduced setup time and greater confidence when specifying tooling for varied processes.

Durable cutting performance from HSS

Manufactured from HSS (high‑speed steel), this rotary cutter offers a robust compromise between toughness and wear resistance for moderate cutting speeds. The material choice helps absorb shocks and resists chipping during interrupted cuts, which is particularly relevant when working on welded joints or rough castings. For operators seeking consistent lifetime and predictable maintenance intervals, the HSS construction delivers stable performance without the brittleness associated with some harder grades, supporting sustained workshop throughput.

Practical application profile for production and repair

Designed for manual and machine use, the burr suits a range of tasks including deburring, chamfering, profiling and removing flash on small components. The 3 mm head length and ball shape facilitate access to narrow features, while the single‑unit packaging supports controlled supply for sensitive operations. For engineering shops, toolrooms and maintenance departments requiring a compact, reliable finishing tool, this cutter is a practical choice that blends accessibility, precision and compatibility.

FAQ

What materials can this rotary burr be used on?
The PFERD rotary burr (SKU 4142015300NW) is manufactured in HSS, which is suited to shaping and deburring a variety of metals, offering a balance of toughness and wear resistance for common steel and ferrous applications.

Is the shank compatible with standard handheld grinders?
Yes, the 6 mm shank fits common small collets and die grinder chucks, allowing use in standard handheld and bench toolholders without additional adaptors.

What does the DIN 8033 designation mean for tool selection?
DIN 8033 (Form F) defines the cutter geometry and tolerances; using a burr compliant with this standard helps ensure predictable fit and performance when matching tooling across machines and documented toolsets.

How fine is the surface finish achievable with the type 3 tooth pattern?
The type 3 tooth pattern provides a compromise between stock removal and surface quality, producing a smooth finish suitable for many finishing operations while maintaining efficient material removal.

Can this cutter be used for repairing castings and weld seams?
The toughness of HSS makes the cutter robust for interrupted cuts encountered on castings and weld seams, with reduced risk of chipping compared with harder but more brittle materials.
