Busch Carbide Stone Setting 90° 413au Burr 1.40mm

Description

Established in 1905, Busch are the leading manufacturers of precision cut rotary accessories and pride themselves on maintaining high quality trend led developments.

This Stone Setting 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 creating a seat in a setting for the stone to drop in easily.

Measuring 1.4mm at the widest point (flat edge), it then tapers at a perfect 90° angle to a sharp point to imitate the shape of a round brilliant cut gem stone.

This range of High-tech burrs are specially designed for working on hard jewellery metals such as platinum, titanium and white gold and will last longer than other burrs.

It has a full working head depth of 1.4mm.

It is designed to be used in conjunction with a pendant drill, hobby drill, micromotor or even a pin vice such asorto cut or grind away leaving a perfectly prepared setting.

Suitable to be used on metal, wax and plastics.

Each burr’s construction consists of a number of teeth/blades (inside of the cup) 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’ () helps prolong the burrs cutting ability.
