Posalux Tools For Use In Jewellery Design

The term “Posalux” is named after a Swiss Company which invented and popularized this shape/size of the tool shank. As a standard, the length of a “Posalux Tool” is 27mm and should have a 6mm through-hole for securing the diamond tool to the holder.  There are a wide range of tool profiles that can be created on the tool i.e Angled, Convex, Concave, 5-Facet, 7-Facet, Line. Diamond size ranges from 0.4mm all the way up to 10mm width.

Proper Posalux Tool Handling/Care Instructions

As with all other single point diamond tools, handle posalux tools with care. Do not touch the diamond tip with your bare hands and do not attempt to clean the diamond tip with anything hard. We recommend using optical lens tissue for cleaning only if absolutely necessary. When not in use, keep the posalux diamond tools covered using the rubber caps supplied. Always send your posalux diamond tools for us to carry out preventive maintenance (re-sharpening). Do not continue to use the tool if obvious lines are showing on the cut surface – The lines are caused by chipping of the diamond edge and this means the diamond edge is blunt/dull. Prolonged usage of a blunt/dull diamond tool will increase chances of  diamond breakage.
