• 5mm diameter
• 100# grit (medium)
• 2.35mm shank (3/32" shank)

These popular Flame shaped Diamond Sintered Burs have a 2.35mm shaft, perfect for engraving, carving and sculpting in glass, stone, ceramics and hard wood, plus grinding work in Lapidary and jewellery. 

Due to the diamonds being sintered they are extremely durable and will produce a clean cut. Maintain their 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 all rotary drills, hand held hobby drills, pendant drills, micro motors and flexible shafts. If you require smaller sizes, finer or coarser grits please contact us.
