Busch 203 HSS Shank Drill 0.70mm

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 Busch 203HSS Shank Drill 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 sharp neat holes.

Measuring 0.70mm wide this Shank Drill bit has been constructed for drilling holes in hard metals such as platinum and 18ct white gold for jewellery applications.

Made from high speed steel, with long life due to high temperature stability.

The working part of the drill bit is 10mm, which is the deepest this drill can produce a hole.

It is recommended that you mark the position of the hole in preparation of drilling.

Designed to be used in conjunction with a pendant drill, hobby drill, micromotor or even a pin vice such asorto cut or grind away a surface.

However, using this drill bit in a bench drill, rather than a pendant motor or flex shaft, will reduce the risk of of breakage.

The drill bit should be used intermittently with light pressure rather than a single, high pressure action.

Using cooling liquid such as drilling oil or ‘Burr Life lubricant’ () will improve tool life.

Whilst using a cooling liquid we also recommend a drill speed of 5000 -8000.

Sold per piece (1-5 items), order 6 and they will be supplied in a box.
