welcome to the widest choice of precious metals on-line direct to the jewellery trade

Cone burr - 3.5mm widest point.
Made from steel. Used in conjunction with a pendant
drill, hobby drill or micromotor to cut or grind away,
shape or give pattern to a surface (usually metal).
Each burr construction is of a number of teeth/blades
(in a given shape) mounted onto a shank (usually 3/32).
The shank fits into the collet/chuck of the drill, and
when turned removes the surface being worked upon.
Quantity of material removed depends on pressure applied
Use of 'Burr Life lubricant'(998 021) helps prolong the
burrs cutting ability.
Various sizes available: 0.9mm - 5.0mm.
