Designed with TWINCUT blade geometry Quick and precise metal removal Perfect for rounding off, shortening and smoothing claws For use with a pendant drill, hobby drill or micromotor Made from tungsten vanadium steel Established in 1905, Busch are the leading manufacturers of precision cut rotary accessories and pride themselves on maintaining high quality trend led developments. This 1.0mm pioneering TWINCUT Concave Burr from Busch is the ultimate tool for chaton work, it has been produced from a single piece of tungsten vanadium steel and is characterised by a stable design which provides a precise power cut and optimum concentricity, ideal for finishing claws. This three-in-one precision tool allows you to safely round off, shorten and smooth claws in one easy step. Designed with TWINCUT blade geometry, the concave burr removes material quickly and precisely and has two chip channels for the rapid discharge of removed material. The cup walls of these burrs are also much thinner, making it easy to work on tightly spaced claws. The Busch TWINCUT Concave Burr is made from tungsten vanadium steel, ensuring both precision quality and a long lifespan, with a rounded cup profile for improved view of work. Recommended speed 2500 - 7000rpm. They are 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 spherical 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.

1mm is the outside diameter of the burr, so no good for rounding 1mm wire, which is what I bought it for. Have now bought the 2.9mm version.
