🔧 What it does & how to use

Diamond burrs are abrasive cutting tools used for engraving, shaping, deburring and fine detail grinding on hard materials such as metal, glass, stone and ceramics. This set of 20 gives a range of head shapes and profiles, letting hobbyists and jewellery makers switch quickly between tasks without changing burrs constantly. They're well suited to watch and clock case work, jewellery finishing, small engraving jobs and general craft or hobby grinding.

• Fit the burr: Insert the shank into your Dremel or rotary tool chuck and tighten securely.
• Choose the shape: Pick the burr head that matches your task — pointed and tapered shapes for detail engraving, rounded or cylindrical heads for grinding and shaping.
• Set the speed: Start on a lower speed setting, especially on delicate materials, to avoid chipping or overheating the workpiece.
• Work gradually: Let the diamond coating do the cutting — apply light, steady pressure rather than forcing the tool.
• Clean as you go: Wipe away dust and debris regularly to keep the cutting surface effective and to check progress.
• Swap heads as needed: Change burrs for different stages of the job — coarser shapes for initial shaping, finer points for detail finishing.
