Busch Burr 6 Bud 4.0mm

Produces a precise power cut Perfect for opening up drill holes for setting For use with a pendant drill, hobby drill or micromotor Made from hardened steel 2.34mm shank Established in 1905, Busch are the leading manufacturers of precision cut rotary accessories and pride themselves on maintaining high quality trend led developments. This No. 6 Bud Burr has been produced from a single piece of hardened steel and is characterised by a stable design which provides a precise power cut and optimum concentricity, ideal for preparing settings. Measuring 4.0mm at its` widest and tapering to a fine point, this bud shape burr opens the setting up to allow for the wideness part of the girdle but then tapers in again to hold the gem securely in place. It has a full working head depth of 6.20mm. It is designed to be used in conjunction with a pendant drill, hobby drill, micromotor or even a pin vice such as 999 AKK or 999 332 to cut or grind away, shape or give pattern to a surface. Suitable to be used on metal, wax and plastics. Each burr`s construction consists of a number of teeth/blades (in a given shape) mounted onto a 2.34mm shank. The shank fits into the collet/chuck of the drill, and when turned these teeth cut into and remove 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.https://www.cooksongold.com/Jewellery-Tools/Busch-Burr-6-Bud-4.0mm-prcode-956-045?p=gs
