It is better suited for continuous cutting where higher edge strength is required to prevent chipping.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv style=\"border-left: 6px solid #47479F; background: white; padding: 15px; border-radius: 0 8px 8px 0;\"\u003e\n\u003cp style=\"font-weight: bold; margin: 0; color: #47479f;\"\u003eQ: Can I use this for stainless steel?\u003c\/p\u003e\n\u003cp style=\"margin: 5px 0 0;\"\u003eA: T9125 is primarily optimized for carbon and alloy steels (P-group). For stainless steel finishing, Tungaloy's T6100 series or AH series grades are recommended.\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: Optimizing CVD Performance\u003c\/h4\u003e\n\u003cp style=\"font-size: 14px; margin-top: 10px;\"\u003eTo maximize tool life with **T9125**, avoid low cutting speeds that can lead to built-up edge (BUE). High speed allows the CVD coating to function at peak thermal efficiency. **Tungaloy Japan** - Engineering excellence for precision 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 Data by cnchome-beyond.com - Global CNC Tool Authority\u003c\/p\u003e","brand":"Tungaloy","offers":[{"title":"Default Title","offer_id":43166213374124,"sku":"TNMG160408L-S T9125","price":69.92,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0592\/7328\/1708\/files\/Tungaloy_TNMG160408L-S_T9125_Left-Hand_Carbide_Turning_Insert_for_Steel_Finishing.jpg?v=1774251324","url":"https:\/\/cnchome-beyond.com\/products\/tungaloy-tnmg160408l-s-t9125-left-hand-carbide-insert","provider":"CNCHome-Beyond","version":"1.0","type":"link"}
