Each side has 3 edges, giving you a total of 6 cutting corners to maximize your ROI.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv style=\"background-color: #47479f; color: white; padding: 25px; text-align: center; border-radius: 0 0 8px 8px;\"\u003e\n\u003ch4 style=\"margin: 0; font-size: 18px;\"\u003eTech Tip: Toughened CVD Grade Application\u003c\/h4\u003e\n\u003cp style=\"font-size: 14px; margin-top: 10px;\"\u003eThe **T9125 CVD grade** is the reliable workhorse of the Tungaloy lineup. It is engineered to withstand impact and thermal cracking. For the best tool life, ensure your machine setup is rigid and use a consistent flow of coolant. **Tungaloy Japan** - Engineering the Future of Machining.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cp style=\"font-size: 10px; color: #eee; text-align: center; margin-top: 5px;\"\u003e© Technical Content by cnchome-beyond.com - Global B2B CNC Authority\u003c\/p\u003e","brand":"Tungaloy","offers":[{"title":"Default Title","offer_id":43166220779692,"sku":"TNMG160408-TM T9125","price":74.52,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0592\/7328\/1708\/files\/Tungaloy_TNMG160408-TM_T9125_Double-Sided_Carbide_Turning_Insert_for_Steel.jpg?v=1774341642","url":"https:\/\/cnchome-beyond.com\/products\/tungaloy-tnmg160408-tm-t9125-durable-steel-insert","provider":"CNCHome-Beyond","version":"1.0","type":"link"}
