Lesley Pyke used our Diamond High Speed FG Dental Burs to carve and engrave these two beautiful pieces of work. The first picture shows the Cone (Coarse) bur in use to carve away the glass, creating a scalloped type effect edge. The second picture shows the Oblate Spheroid (Medium) bur in use which will engrave large areas. And the last picture of the bee shows the Flame (Extra Fine) bur which is ideal for delicate fur or hair engraving. Lesley uses an adaptor to convert her handpiece to accept burrs that have a shank size of 2.35mm (3/32") to 1.6mm (1/16"). The drill Lesley uses here is a Micromotor.
