Busch Carbide Burr 1au Round 3.5mm

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 1AU Round Burr from Busch is precision made from isostatically compressed, fine grain carbide material.

With excellent dimensional accuracy and cutting power, this range of carbide high-tech burrs is specially designed for working on hard jewellery metals such as platinum, titanium and white gold.

Measuring 3.5mm at its’ widest, this sphere shape burr can open up a setting, but can also be used to create a slot in each claw to allow for the widest part of the girdle to sit in and be held securely before claws are pushed over the stone.

It is designed to be used in conjunction with a pendant drill, hobby drill, micromotor or even a pin vice to cut or grind away, shape or give pattern to a surface.

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’ () helps prolong the burrs cutting ability.
