The Dremel 536 Brass Wire Cup Brush is a rotary tool accessory designed for cleaning and surface preparation without damaging softer metals. This cup brush features brass wire bristles that are non-sparking and softer than steel, making it ideal for work on delicate metal surfaces where scratching must be avoided. The brass construction makes this cup brush particularly suitable for cleaning, deburring and polishing gold, copper and brass components without leaving marks or surface damage. The 13mm working diameter and 3.2mm shank provide compatibility with Dremel rotary tools and similar multi-tools, whilst the compact size allows access to detailed work areas. At just 9.1g, this lightweight accessory minimises fatigue during extended use and is well-suited to jewellery making, precision metalwork, restoration projects and intricate cleaning tasks where softer metals require a gentler touch than steel brushes can provide.
