{"product_id":"044-504-c-max-burin","title":"GRS® C-Max Burin","description":"\u003cp\u003eThis GRS Burin is a special tungsten carbide graver made for hand engraving, especially intaglio print making. The material is GRS C-Max, a grade of carbide that has the ability to hold a sharp edge for an incredibly long time. Because this material is a very hard tungsten carbide, it can only be sharpened using a diamond abrasive such as the 5\" Diamond Wheels (\u003ca href=\"http:\/\/www.zikjewelrytools.com\/products\/002-055-diamond-wheel-5-600-grit-medium\" target=\"_blank\"\u003e#002-055\u003c\/a\u003e) for Power Hone (\u003ca href=\"http:\/\/www.zikjewelrytools.com\/products\/004-525b-power-hone-basic\" target=\"_blank\"\u003e#001-525B\u003c\/a\u003e) — ordinary sharpening stones or grinding wheels will not work on this material.\u003c\/p\u003e\n\u003cp\u003eThe burin is made from a 0.125\" (3.17mm) diameter round blank approximately 3\" (75mm) long. On the top front of the burin are two ground reference surfaces forming a 90° square edge. This provides a clamping surface for resharpening using most GRS sharpening fixtures.\u003c\/p\u003e\n\u003cp\u003eBehind the 35° front graver face is a relief face sharpened at 15°. The burin sides are thinned by grinding a 2.5° relief surface on both sides approximately 0.6\" (15mm) long.\u003c\/p\u003e\n\u003cp\u003eHeel construction: 2 flat ground surfaces approximately 0.25\" (6mm) long at 12° elevation angle forming a 100° included V-point. This creates a slightly wider point than a traditional square graver.\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eKit includes 1 C-Max Burin, 1 Graver Handle, and 1 Allen Wrench. \u003ca href=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0251\/1947\/files\/BURIN_INSTRUCTIONS.pdf?14293020237808602457\" target=\"_blank\"\u003eInstructions.\u003c\/a\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GRS","offers":[{"title":"C-Max Burin Kit","offer_id":343463531,"sku":"044-504","price":79.0,"currency_code":"USD","in_stock":true},{"title":"C-Max Burin Only","offer_id":343463533,"sku":"022-620","price":44.5,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0251\/1947\/products\/044-504_1-1Wa.jpg?v=1738441503","url":"https:\/\/zikjewelrytools.com\/products\/044-504-c-max-burin","provider":"DECOZE JEWELRY TOOLS","version":"1.0","type":"link"}
