The Dremel 520 Impregnated Polishing Wheel is a precision rotary tool accessory designed for achieving high lustre finishes on metalwork and hard plastics. This silicon carbide-impregnated polishing wheel eliminates the need for separate polishing compounds, as the abrasive and cooling lubricant are integrated directly into the wheel material. Ideal for light stock removal and fine polishing applications, this accessory works effectively on steel, aluminium, brass, silver, gold and hard plastics. The integrated cooling lubricant helps prevent overheating during extended polishing sessions whilst maintaining consistent results. With its compact 13.2mm working diameter and standard 3.2mm shank, this polishing wheel fits all Dremel rotary tools and compatible multi-tools. The pre-impregnated design offers convenient, mess-free operation compared to traditional polishing compounds, making it particularly suitable for jewellery finishing, metal restoration work and detailed polishing tasks in confined spaces.
