Diamond Sintered Burrs Ball


Choose from the following:

  • 6mm diameter, 120 grit , 2.35mm (3/32") shank
  • 3mm diameter, 170 grit, 2.35mm (3/32") shank

These 6mm and 3mm Diamond Sintered Ball Burrs have a 2.35mm (3/32") shank for use in a rotary tool such as a Dremel, a pendant drill, a flexible shaft or in a high speed handpiece or micro motor. Ideal for engraving, carving and sculpting in glass, stone, ceramics and hard wood, plus grinding work in Lapidary and jewellery making.

Due to the diamonds being sintered they are extremely durable. In order to get the best from our Diamond Sintered Ball burs, please ensure to maintain their efficiency by occasionally cleaning them with a dressing stone or aluminium oxide stick. Use with water, let the drill do the work and apply very little pressure.
