If you're looking to carve metal, antler or wood, try our small carbide ball burrs, also on a 2.35mm shank.

Please note, some people choose a diamond ball burr to drill holes with; however, they are not designed for this purpose and you will find that a Small Diamond Drill Bit or a Small Diamond Core Drill is more suitable for the task.

Looking for Dremel 7103? Then choose our 2mm diamond ball burrs on this page which are the equivalent tool.

Always wear sufficient safety goggles and a face mask and be careful not to exceed a drill speed of 12,000rpm and use with very little to no pressure.
