This is a drill bit with drills of 2.0 to 3.5 mm thickness. These drills can be used to drill into the clay or metal.
Metal drills in sizes 2.0, 2.1, 2.2, 2.3, 2.4, 2.5, 2.6, 2.7, 2.8, 2.9, 3.0, 3.1, 3.2, 3.3, 3.4, 3.5, mm in sleeve.
Drilling in silverclay is the easiest if it is dry and unfired.
Hold the crank between two fingers and give it light pressure while turning the drill slowly. Start with a thin drill and make the hole larger with a next drill (max. In 0.5mm increments) to the desired size. Use a handheld drill holder for more control and ease of drilling.
