However, when moving to ductile iron (GGG), reduce the speed slightly and monitor the flank for edge chipping, as ductile iron is more prone to mechanical impact.\n    \u003c\/p\u003e\n  \u003c\/div\u003e\n\n\u003c\/div\u003e","brand":"ZCC.CT","offers":[{"title":"Default Title","offer_id":43493200986284,"sku":"APKT11T308-PM YBD252","price":64.38,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0592\/7328\/1708\/files\/ZCC.CT_APKT11T308-PM_YBD252_Black_Diamond_Grade_Insert_for_Cast_Iron_Milling.jpg?v=1776588487","url":"https:\/\/cnchome-beyond.com\/products\/zccct-apkt11t308-pm-ybd252-milling-insert","provider":"CNCHome-Beyond","version":"1.0","type":"link"}
