This Glardon Vallorbe® Valtitan™ half-round needle file is ideal for refining both flat and curved surfaces; it is highly recommended for working with platinum and other hard metals. It has one flat and one rounded side with teeth on both; the file width tapers to a point. The tapering width and the fine point allow it to access crevices and small openings and details, corners and the inside of ring shanks and bezels.
This file has a Swiss cut #0; Swiss-cut files are graded by the number of teeth, counting teeth perpendicular to the long axis of the file. In all cut styles, the higher the number, the finer its cut.
A double-cut file features two sets of evenly spaced teeth set in two directions, one at a slightly different angle than the other. Double-cut files are designed to cut more aggressively, maximizing the work of each stroke to remove more metal with fewer strokes. At the end of the stroke, the file should be lifted from the workpiece and repositioned for the next stroke; dragging the file backward against the metal can mar the metal and damage the teeth.
Needle files feature a miniature profile with a shorter cutting surface (typically about half their length) and round, narrow handles. These small files are ideal for working on fine details and in small areas of the workpiece; they're ideal when access and surface finish take priority over metal removal. Though they can be used as-is, securing the file in a handle (available separately) improves control for better precision and tool safety.
Valtitan™ files deliver better performance on hard-to-file surfaces (such as platinum and titanium), have great corrosion resistance and long service life. Valtitan files are specially treated for hardness (65HRC, the hardest steel file available). The teeth on these files resist metal accumulation so that a quick, sharp knock is usually enough to clear them.
The first choice for most jewelers, Glardon Vallorbe® files are manufactured to the highest production standards, made in Switzerland of the finest heat-tempered chrome-alloy steel. The files are precision-ground to cut quickly and accurately and to last longer than just about any other file on the market.
