A traditional hand drill for slow precise drilling of stone, metal or wood. Use the appropriate drill bit sizes. 2 collets for 0.5mm to 2mm shank. Diamond for glass and stones, HSS or carbide for metal and wood. Advantage of slow drilling is when water is required when drilling glass, shells and stones. Construct a shallow well with plastercine or beewax, fill with water and commence slow smooth jiggling. A spray of lithium grease into the wood handle hole helps in ultra smooth motion expecially with the assistance of the brass flywheel momentum.
Jewellers, watch makers, gem artists and scale modellers will find this drill easy to use and precise.
