These solid carbide ram rollers from Busch are 6mm in diameter, mount on a 3\/32\" (2.35 mm) shank for flex shaft use, and are offered with either 22 faces or 36 faces.\u003c\/p\u003e\u003cp\u003eThe 22-face roller covers a slightly broader area than the 36-face version, and the difference in effect is slight. Both are intended for gold, platinum, and silver castings, giving fast, controlled surface refinement before final finishing.\u003c\/p\u003e\u003ch3\u003eFeatures\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction for long service life\u003c\/li\u003e\n\u003cli\u003eChoice of 22 faces or 36 faces\u003c\/li\u003e\n\u003cli\u003eCylindrical ram roller design for efficient porosity removal\u003c\/li\u003e\n\u003cli\u003eFaceted profiles for controlled surface compression\u003c\/li\u003e\n\u003cli\u003e3\/32\" (2.35 mm) shank fits flex shaft handpieces\u003c\/li\u003e\n\u003cli\u003eMaximum working speed of 10,000 RPM\u003c\/li\u003e\n\u003cli\u003eSuited to gold, platinum, and silver castings\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eAvailable Options\u003c\/h3\u003e\u003ctable\u003e\n\u003ctr\u003e\n\u003cth\u003ePart #\u003c\/th\u003e\n\u003cth\u003eFace Count\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBAU118.470\u003c\/td\u003e\n\u003ctd\u003e22 Faces\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBAU118.471\u003c\/td\u003e\n\u003ctd\u003e36 Faces\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\u003ch3\u003eNotes\u003c\/h3\u003e\u003cp\u003eUse light, controlled pressure at or below the maximum recommended speed.
