Swiss Fig. 1 Ball Burs 0.50mm-3.70mm

Fig. 1 ball burs cut round seats and hollows, the profile jewelers reach for when setting stones, opening seats, and doing general metalsmithing work. These are made in Switzerland by Dentsply Maillefer from tungsten-vanadium steel, and they are among the most popular burs Otto Frei carries: many professional jewelers prefer them over higher-priced alternatives for their consistent cut quality and value. Twenty-seven sizes run from 0.50mm to 3.70mm, covering fine detail work through larger seat openings. Sold in multiples of 6 per size.
