05 033 077 NIQUA Wheel Brush 42100M – Black Chungking Bristles, 77 × 4 mm (Pack of 10)

The NIQUA Wheel Brush 42100M (77 × 4 mm) is a heavy-duty, high-density polishing brush developed for demanding applications in professional jewellery workshops. Featuring premium black Chungking bristles, this brush provides firm, powerful abrasion—perfect for removing oxidation, smoothing rough surfaces, refining castings and preparing metal pieces for subsequent polishing steps.

With its extra-large 77 mm diameter and four-layer construction, the brush offers outstanding durability, density and surface coverage. This makes it especially effective for working on larger jewellery items, broad metal surfaces and areas requiring stronger cleaning or pre-polishing. The 2.35 mm shank ensures compatibility with all standard rotary tools and micromotors.

Delivered in a pack of 10, it provides long-lasting reliability and consistent results for professional workshops.
