Featuring a robust \u003cstrong\u003e25mm precision cylindrical clamping shank\u003c\/strong\u003e and a 250mm overall length (S-type standard specification), this tool is designed for demanding environments like oil-field component manufacturing, hydraulic cylinder boring, and heavy flange profiling. Utilizing an ultra-stable \u003cstrong\u003eM-type Multi-Lock clamping system\u003c\/strong\u003e (which combines a heavy-duty top clamp bridge with an internal dimple pulling pin), it delivers unparalleled clamping force to hold negative inserts securely under extreme cutting impacts and continuous high-feed parameters.\u003c\/p\u003e\n\u003cp\u003eWith its 95-degree approach lead angle, the tool head geometry allows for deep internal shoulder boring, counterboring, and blind-hole facing without dragging the tool shank. It is optimized to hold highly economical 80-degree trigon double-sided indexable inserts, specifically the industry-standard \u003cstrong\u003eWNMG 060404 \/ WNMG 060408\u003c\/strong\u003e series (6 cutting edges per insert). The specialized structural head layout allows this 25mm bar to clear internal diameters down to a \u003cstrong\u003e32mm minimum bore diameter\u003c\/strong\u003e, facilitating an open pathway for rapid chip evacuation. When paired with advanced multi-layer CVD-coated carbide grades with robust chipbreaker geometries for carbon steel or specialized PVD nano-structured inserts for sticky stainless steel, this configuration tightly curls and snaps swarf into short \"C\"-shaped segments. This prevents dangerous \"bird-nesting\" strings from scratching the internal bore surfaces or causing premature cutting tip catastrophic failure.\u003c\/p\u003e\n\u003cdiv style=\"border: 2px solid #47479F; border-radius: 6px; padding: 20px; margin: 25px 0; background-color: #fbfbfe;\"\u003e\n\u003ch3 style=\"margin-top: 0; color: #47479f; font-size: 16px; border-bottom: 1px solid #e0e0e0; padding-bottom: 8px;\"\u003eModel Nomenclature Decoder: S25S-MWLNR06\u003c\/h3\u003e\n\u003cdiv style=\"margin-top: 12px; font-family: monospace; font-size: 13px;\"\u003e\n\u003cdiv style=\"display: block; margin-bottom: 6px; border: 1px solid #cccccc; padding: 8px; border-radius: 4px; background: #ffffff;\"\u003e\n\u003cstrong\u003eS\u003c\/strong\u003e - Solid High-Tensile Structural Alloy Steel Body Core\u003c\/div\u003e\n\u003cdiv style=\"display: block; margin-bottom: 6px; border: 1px solid #cccccc; padding: 8px; border-radius: 4px; background: #ffffff;\"\u003e\n\u003cstrong\u003e25\u003c\/strong\u003e - 25mm Precision Cylindrical Clamping Shank Diameter (Heavy-duty high-torque layout)\u003c\/div\u003e\n\u003cdiv style=\"display: block; margin-bottom: 6px; border: 1px solid #cccccc; padding: 8px; border-radius: 4px; background: #ffffff;\"\u003e\n\u003cstrong\u003eS\u003c\/strong\u003e - 250mm Standard Industrial Core Total Tool Length (Deep-reach capacity specification)\u003c\/div\u003e\n\u003cdiv style=\"display: block; margin-bottom: 6px; border: 1px solid #cccccc; padding: 8px; border-radius: 4px; background: #ffffff;\"\u003e\n\u003cstrong\u003eM\u003c\/strong\u003e - Multi-Lock Clamping Design (Double clamping mechanism combining top bridge clamp and internal pin)\u003c\/div\u003e\n\u003cdiv style=\"display: block; margin-bottom: 6px; border: 1px solid #cccccc; padding: 8px; border-radius: 4px; background: #ffffff;\"\u003e\n\u003cstrong\u003eW\u003c\/strong\u003e - 80° Trigon Geometric Negative Insert Shape Pocket Seating (WNMG 0604 format)\u003c\/div\u003e\n\u003cdiv style=\"display: block; margin-bottom: 6px; border: 1px solid #cccccc; padding: 8px; border-radius: 4px; background: #ffffff;\"\u003e\n\u003cstrong\u003eL\u003c\/strong\u003e - 95° Approach Lead Angle (Optimized for square internal steps, profiling, and deep shoulder facing)\u003c\/div\u003e\n\u003cdiv style=\"display: block; margin-bottom: 6px; border: 1px solid #cccccc; padding: 8px; border-radius: 4px; background: #ffffff;\"\u003e\n\u003cstrong\u003eN\u003c\/strong\u003e - 0° Normal Relief Profile Clearance Angle (Negative insert layout for maximum cutting edge strength)\u003c\/div\u003e\n\u003cdiv style=\"display: block; margin-bottom: 6px; border: 1px solid #47479F; padding: 8px; border-radius: 4px; background: #47479F; color: #ffffff;\"\u003e\n\u003cstrong\u003eR\u003c\/strong\u003e - Right-Hand Tool Cutting Rotation Direction (Standard CNC lathe internal toolpath orientation)\u003c\/div\u003e\n\u003cdiv style=\"display: block; border: 1px solid #47479F; padding: 8px; border-radius: 4px; background: #47479F; color: #ffffff;\"\u003e\n\u003cstrong\u003e06\u003c\/strong\u003e - Accommodates Standard 6mm Inscribed Circle Sized Indexable Inserts (WNMG 060404 \/ WNMG 060408)\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv style=\"border: 2px solid #47479F; border-radius: 6px; padding: 15px; margin-bottom: 25px; background-color: #47479f; color: #ffffff; text-align: center;\"\u003e\n\u003cp style=\"margin: 0 0 10px 0; font-weight: bold; font-size: 16px;\"\u003eRunning counter-boring cycles or left-hand toolpaths on sub-spindles?\u003c\/p\u003e\n\u003cspan style=\"color: #47479f;\"\u003e\u003cspan style=\"display: inline-block; background-color: rgb(255, 255, 255); padding: 8px 20px; border-radius: 4px; text-decoration-thickness: initial; text-decoration-style: initial; text-decoration-color: initial;\"\u003e\u003cb\u003e \u003ca href=\"https:\/\/cnchome-beyond.com\/search?q=wnmg0604\" target=\"_blank\" rel=\"noopener\"\u003eSwitch to the Mirror S25S-MWLNL06 (Left Hand) Tool Bar → \u003c\/a\u003e\u003c\/b\u003e\u003c\/span\u003e\u003c\/span\u003e\n\u003c\/div\u003e\n\u003ch2 style=\"color: #47479f; font-size: 20px; border-bottom: 2px solid #47479F; padding-bottom: 5px; margin-top: 30px;\"\u003e2.
