GRAVERS, SCOR- PERS, SCRAPERS & DEBURRING


Tools for engraving, setting, chasing, sculpting, etc are inexpensive compared with the cost of essential tooling to practice other crafts. One is able to buy the essentials for a lifetime of manufacturing, leaving only the expense of replenishing consumables.


At Cousins Material House Ltd we distribute a full range of Swiss Vallorbe gravers and accessories for a wide variety of modern day workshop applications for manufacturing, repairing, craftwork, hobbyists and work in the ne arts.


With various industries demanding the highest quality tools, Vallorbe gravers have been the forefront market leader in this eld. Used by industry experts all over the world on millions of pieces there is very little the Vallorbe Graver has not touched.


Some useful information about gravers…


Te creator of te indler oupe, Bernard indler developed an inventive solution to a problem in te eellers trade tat ad never been satisfactorily solved indler created te uniue and very popular indler cale ic embodies specially graduated scales in a magnier and tus enables te liely eigts to be read off uite straigtforardly, even ile te stones are still mounted


Bernard indler enoyed a long career in te diamond trade, ic e muc loved and in ic e ad many years of experience in inspecting and valuing precious stones mostly in preparation for mounting in eellers items) Combined it many years experience in precision engineering, is insigt canged te ay eellers or and estimate precious stones

Te focus option allos you to focus te lines better

Te ligt enters troug a narro slit and is ten dispersed troug a series of prisms Because prism spectroscopes are based on dispersion, te blue area of te spectrum is more spread out and te red parts are more condensed tan te diffraction grating types

Gravers come in various shapes, sizes and metal qualities.


Metal types: Tools Steel (WS) the standard graver, keeps a tough sharp edge maintaining hours of production usage.


High Speed Steel (HSS) this tougher graver keeps a sharp edge for a considerably longer time than normal tool steel gravers (WS).


 Gravers can be used on a whole variety of metals or materials including gold, silver, platinum, palladium, titanium, copper, brass, bronze, pewter, gilding metal, steel, ivory, bone, wood, plastics and aluminium.


All gravers have makings from the manufacturer which indicates the size and metal quality. HSS gravers always have a yellow paint mark on the tang of the graver; this identies the mounting point for the handle. Additionally measure the width of the graver and compare with the graver chart below, to determine the size. Graver handles come in different shapes and sizes, it is advisable to replace the handle with the graver to ensure optimum grip between handle and graver.

Preparing a graver… A graver tool has to be of a certain length to suit the hand of the user. Held in working position, the end of the tool should project half to three-quarters of an inch beyond the thumb. A graver, when brought, will be too long and will have to be shortened. If only a small reduction is required a small piece can be broken off the tang before the handle is tted. The tang is not as hard as the rest of the tool and the broken end should be led or grinded to a point so that it can be easily inserted into the handle.
