This black EVE universal silicone polishing knife-edge wheel is ideal for smoothing and shaping precious metals with a flex shaft or other rotary tool. The medium abrasive is great for pre-polishing tasks; it smooths and refines edges and surfaces. For best results, use at 7,000–10,000rpm with very light pressure. The wheel has a 1/16" center hole; use with a mandrel (available separately).
Max. speed: 20,000rpm
