The Cocker-Weber #4C Superior Chungking Bristle Brush is a professional-quality hard polishing brush designed for jewellery, goldsmithing and precision metal finishing. Manufactured in the USA, it combines premium Chungking bristles with a seasoned hardwood centre for durability, stability and consistent polishing performance.

Featuring a 4-row centred bristle configuration, the #4C provides a firm and controlled polishing action while retaining the natural flexibility of Chungking bristle. Its hard grade makes it particularly suitable for more demanding polishing and finishing operations where greater polishing action is required.

With a Ø67 mm brush diameter and 9.5 mm trim length, the compact profile provides excellent control when polishing jewellery, precious metals and other detailed metal components.

The seasoned hardwood centre provides strength and stability during operation, while the 6.35 mm arbor hole allows the brush to be mounted on compatible polishing motors and tapered spindles.

The Cocker-Weber #4C can be used with suitable polishing compounds for finishing gold, silver and other compatible metals. Its combination of hard Chungking bristles and professional construction makes it an excellent choice for jewellers, goldsmiths and professional polishing workshops.
