Busch Stone Setting Burr no 413 - available in 2mm-8mm.

The Busch professional quality tool steel stone setting burrs are ideal for creating a perfectly shaped hole to set facetted stones into dry clay and metal. The burr has a 90° point, and will give you a perfectly shaped cone to flush set most facetted stones. The burr can also be used for grinding, shaping, and adding patterns, and they're great for enlarging or bevelling holes.

Use this burr by hand in a pin vice, or with a flexshaft, pendant drill, hobby drill or micromotor.

This burr is manufactured from a high quality tool steel to provide a precision cut and long working life. If used on metal (rather than dry silver clay) use with burr life oil or silicone lubricant oil to keep the burr sharp.
