Used in connection with the Dremel drill about its vertical support, allows the positioning and the maintenance of relatively small parts and greatly improves the "speed" of processing when a series of holes to be produced. The only flaw would be a little too much play on the lower guide of the mobile jaw, which tends to rise slightly and lose some horizontal alignment with the fixed jaw. The button of "disengagement" of fast moving jaw is interesting, but no more. We must first loosen the jaw before "disengage" the function of the handle screw. Interesting product, which could be achieved with little more tight tolerances. (This keeping in mind that, indeed, the "chips" can always come slip into the gap between lower jaw and chassis).
