A new mini composite tool from Mueller-Kueps is now available. The Micro Die grinder with “Bionigrip” is used for precise grinding and milling with a variable speed twist throttle to provide speed control. This tool features maximum concentricity through its precision collet, minimal vibration and less kick back. It provides low noise level and easy handling from the “Bionigrip” surface. The carbide milling and grinding burrs 5-piece kit allows the user to drill out hard metals such as broken taps or drill bits. These can also drill out broken bolts, cut through the outer race of a bearing, grind bumpers, dashboards and more.
