The set allows jewelers to quickly remove casting skin, grow lines, porosity, and tool scars in hard-to-reach areas — between gallery wires, between split shanks, and in filigree work. This three-piece set is designed to reduce or virtually eliminate the traditional burnishing method, delivering consistent results across multiple finishing stages.\u003c\/p\u003e\n\u003cp\u003eMount each burnisher in a flexshaft or micromotor and use at speeds up to 30,000 RPM to achieve the desired finish.\u003c\/p\u003e\n\u003cp\u003eThe higher the number of facets, the smoother and brighter the resulting surface.
