Busch Burr 411 Cup 1.8mm

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 Cup 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 finishing claws in a setting.

Measuring 1.8mm at its’ widest inner point and giving it a working diameter of 1.4mm, it is then rounded off perfectly to create an inner cup shape.

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 perfect dome shape.

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.
