{"product_id":"carbide-inside-ring-cylinder-burs-fine-extra-coarse-3-32","title":"Carbide Inside Ring Cylinder Finishing Burs-Fine to Coarse","description":"\u003cp\u003eThese burs trim and true the inside of a ring band, cutting fast and staying controlled as you clean up the interior after sizing or casting. The cylinder head is sized specifically for inside ring work and seats solidly in a 3\/32\" collet, so the cut feels stable and predictable on a flex shaft or micromotor. Four cutting aggressions, Fine through Extra Coarse, cover every stage of interior ring work, from light refining to heavy stock removal.\u003c\/p\u003e\n\u003ch3\u003eFeatures\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eCylinder bur profile sized specifically for inside ring trimming and clean-up\u003c\/li\u003e\n\u003cli\u003eMounted on 3\/32\" shanks for use with standard flex shaft and micromotor handpieces\u003c\/li\u003e\n\u003cli\u003eSingle head size across all grits for consistent feel when switching cutting aggressions\u003c\/li\u003e\n\u003cli\u003eEngineered for rapid metal removal while maintaining smooth, predictable control\u003c\/li\u003e\n\u003cli\u003eChoice of four cutting aggressions: Fine, Medium, Coarse, and Extra Coarse\u003c\/li\u003e\n\u003cli\u003eDurable carbide construction for extended service life in daily bench use\u003c\/li\u003e\n\u003cli\u003eManufactured in the USA\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eAvailable Options\u003c\/h3\u003e\n\u003ctable\u003e\n\u003ctr\u003e\n\u003cth\u003ePart #\u003c\/th\u003e\n\u003cth\u003eGrit\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e120.295\u003c\/td\u003e\n\u003ctd\u003eFine\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e120.296\u003c\/td\u003e\n\u003ctd\u003eMedium\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e120.297\u003c\/td\u003e\n\u003ctd\u003eCoarse\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e120.298\u003c\/td\u003e\n\u003ctd\u003eExtra Coarse\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\u003ch3\u003eCompatibility\u003c\/h3\u003e\n\u003cp\u003eThe straight 3\/32\" shank fits standard flex shaft and micromotor handpieces and collets.\u003c\/p\u003e\n\u003ch3\u003eNotes\u003c\/h3\u003e\n\u003cp\u003eUse light, controlled pressure and let the bur do the work when trimming ring interiors, especially in softer alloys.
