So called because of their Bongo Drum shape, these Diamond Sintered Burrs are 6mm diameter with a 3mm depth, mounted on a 2.35mm shank (3/32"). These carving points are perfect for engraving, carving and sculpting in glass, stone, ceramics, porcelain and very hard woods, plus grinding work in Lapidary and jewellery.
Due to the diamonds being sintered they are extremely durable. Maintain their cutting efficiency by occasionally cleaning the sintered burs with a dressing stone or aluminium oxide stick, use with water, let the drill do the work, and apply very little pressure.
For use with rotary tools, pendant drills, micro motors or a flex shaft.
