Margin roller burnishers are the professional's choice for eliminating porosity from gold, platinum, and silver without metal loss. Run them at high speed in a rotary handpiece on their 3\/32 in shank while applying light pressure, moving the tool back and forth across the porosity in several directions until the surface closes. Less aggressive than Porosity Killer and Ram Burnishers, margin roller burnishers offer a controlled approach to porosity correction, ideal when a gentler touch is required.\u003c\/p\u003e\u003ch3\u003eFeatures\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eCorrects porosity in gold, platinum, and silver without metal loss\u003c\/li\u003e\n\u003cli\u003eDesigned for use at high speed in a rotary handpiece\u003c\/li\u003e\n\u003cli\u003eApply light pressure while moving back and forth across porosity in several directions\u003c\/li\u003e\n\u003cli\u003eLess aggressive than Porosity Killer and Ram Burnishers for more controlled results\u003c\/li\u003e\n\u003cli\u003e3\/32 in mandrel shank fits standard rotary handpieces\u003c\/li\u003e\n\u003cli\u003eAvailable in three roller sizes to suit different applications\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\u003eRoller Size\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e118.081\u003c\/td\u003e\n\u003ctd\u003e8mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e118.082\u003c\/td\u003e\n\u003ctd\u003e10mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e118.083\u003c\/td\u003e\n\u003ctd\u003e12mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e","brand":"Otto Frei","offers":[{"title":"8mm","offer_id":47551754010838,"sku":"118.081","price":41.9,"currency_code":"USD","in_stock":true},{"title":"10mm","offer_id":47551754043606,"sku":"118.082","price":46.5,"currency_code":"USD","in_stock":true},{"title":"12mm","offer_id":47551754076374,"sku":"118.083","price":66.7,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0609\/9832\/0342\/files\/margin-roller-burnishers-otto-frei.jpg?v=1719955110","url":"https:\/\/www.ottofrei.com\/it\/products\/margin-roller-burnishers-8-10-12mm-3-32-shank","provider":"Otto Frei","version":"1.0","type":"link"}
