The actual chip thickness becomes less than the set feed rate, distributing the heat and mechanical pressure over a wider portion of the SNMG insert's cutting edge. This structure lowers the radial force component, directing cutting energy along the rigid machine bedways to minimize vibration.\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"ucp-faq-wrapper\"\u003e\n\u003cdiv class=\"ucp-faq-q\"\u003eQuestion: When should I choose an M-type double-clamp toolholder over a standard P-type lever toolholder?\u003c\/div\u003e\n\u003cdiv class=\"ucp-faq-a\"\u003eAnswer: Standard P-type toolholders use an internal lever mechanism that leaves the top face unobstructed for chip flow, but they can struggle under fluctuating high-torque demands. BEYOND's M-type double clamp adds an external overhead claw to the internal pull-back pin. This dual clamping action is highly recommended for interrupted cuts, hard forgings, and heavy scale removal.\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"ucp-faq-wrapper\"\u003e\n\u003cdiv class=\"ucp-faq-q\"\u003eQuestion: Can the MSDNN2525M15 toolholder cut clean 90-degree square shoulders?\u003c\/div\u003e\n\u003cdiv class=\"ucp-faq-a\"\u003eAnswer: No, because of its neutral head design and 63° entering angle, it cannot turn sharp 90° square steps or shoulders. It is designed specifically for facing, straight longitudinal roughing, and chamfering where large metal removal volume is the primary metric.\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c!-- BASE PERFORMANCE AND GRADE COMPARISON TIPS --\u003e\n\u003cdiv style=\"margin-top: 30px; font-size: 0.85rem; color: #555; background: #eee; padding: 15px; border-radius: 4px;\"\u003e\n\u003cstrong\u003eAdvanced Metalworking Tips \u0026amp; Troubleshooting Guide:\u003c\/strong\u003e\u003cbr\u003e• \u003cstrong\u003eGrade Comparison Tip:\u003c\/strong\u003e When moving from continuous cuts to heavy interrupted machining on scale-covered forgings, switch from a pure CVD alumina coating to a high-density PVD TiAlN grade to prevent thermal micro-cracking.\u003cbr\u003e• \u003cstrong\u003eTroubleshooting Notch Wear:\u003c\/strong\u003e If severe localization notch wear develops at your depth-of-cut ($a_p$) line, try varying the depth of cut slightly between passes or change to an aggressive roughing chipbreaker profile.\u003cbr\u003e• \u003cstrong\u003eWorkpiece Matrix Rule:\u003c\/strong\u003e Always ensure adequate flood coolant volume when machining M-class stainless steel to control heat buildup and avoid premature plastic deformation of the tool's edge geometry.\u003c\/div\u003e\n\u003c\/div\u003e","brand":"BEYOND","offers":[{"title":"Default Title","offer_id":43396654792876,"sku":"MSDNN2525M15","price":33.16,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0592\/7328\/1708\/files\/BEYOND-MSDNN2525M15-CNC-turning-toolholder-25x25mm-shank-for-SNMG1506-inserts.jpg?v=1781591614","url":"https:\/\/cnchome-beyond.com\/products\/msdnn2525m15-external-turning-tool-holder-snmg-beyond","provider":"CNCHome-Beyond","version":"1.0","type":"link"}
