🏷️ Busch #820 Diamond Coated Wheel Bur (Medium Grit) - 2.35mm Shaft [EOL]

Product Description

The Busch #820 Diamond Coated Wheel Bur is a precision rotary tool designed for grinding, shaping, refining, and finishing hard materials used in jewellery making and stone setting. Its thin wheel profile provides excellent access for working along edges, creating grooves, refining slots, and making controlled cuts in detailed or confined areas.

Coated with medium-grit diamond abrasive, the #820 provides an effective balance between material removal and surface control. Unlike conventional toothed burs, the diamond-coated surface works by abrasion, making it particularly useful on gemstones, glass, ceramics, and other hard or brittle materials. The standard Ø2.35 mm shaft fits common jewellery flex shaft and micromotor handpieces.
