🏷️ Busch #842 Diamond Coated Cylinder Flat Bur (Medium Grit) - 2.35mm Shaft [EOL]

Product Description

The Busch #842 Diamond Coated Cylinder Flat Bur is a precision rotary tool designed for grinding, shaping, levelling, and refining hard materials used in jewellery making and stone setting. Its straight cylindrical profile with a flat end is particularly useful for working on flat surfaces, straight walls, recesses, edges, and other areas where controlled abrasive removal is required.

Coated with medium-grit diamond abrasive, the #842 provides an excellent balance between efficient material removal and surface control. Unlike conventional toothed burs, the diamond-coated surface removes material through abrasion, making it particularly useful for gemstones, glass, ceramics, and other hard or brittle materials. The standard Ø2.35 mm shaft fits common jewellery flex shaft and micromotor handpieces.
