Utilizing a robust \u003cstrong\u003e16mm precision-ground solid structural alloy steel shank\u003c\/strong\u003e with an extended 180mm overall length (Q-type standard), this boring bar provides the ultimate cross-sectional density and moment of inertia required to absorb intense torsional deflection in deep-reach internal turning setups. The primary mechanical breakthrough of this holder is its \u003cstrong\u003eW-type Double Clamping System\u003c\/strong\u003e. By binding the negative insert from both the center pin pivot and an over-the-top high-tensile clamp plate, it achieves zero-play insert encapsulation. This rigid architecture stops insert lifting or micro-shifting when encountering variable depths of cut (DOC) or heavy scaling, ensuring a safe minimum machining \u003cstrong\u003ebore diameter of 22mm\u003c\/strong\u003e.\u003c\/p\u003e\n\u003cp\u003eFeaturing an optimized 95-degree approach lead angle (L-type geometry), this holder offers great versatility for parallel boring up to straight shoulder faces. The 95° layout is mathematically crucial because it channels the dominant cutting resistance forces straight down the longitudinal core of the 16mm steel stem rather than pushing sideways, dramatically eliminating micro-chatter, tool push-off, and borehole taper defects. The pocket seat is machined to absolute tolerances and embedded with a hardened carbide shim sleeve to host standard 95-degree double-sided negative trigon inserts, specifically the \u003cstrong\u003eWNMG 080404 \/ WNMG 080408 \/ WNMG 080412\u003c\/strong\u003e series. Boasting 6 highly economical cutting edges per insert, this tooling configuration handles severe chip loads and aggressive material removal rates (MRR) smoothly, maintaining rigid surface finishes and repeatable dimensional consistency across extended B2B production cycles.\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: S16Q-SWLNR08 (ISO \/ National Standard Chart Compliant)\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 (Maximum static anti-deflection stiffness)\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\u003e16\u003c\/strong\u003e - 16mm Precision Cylindrical Clamping Shank Diameter (Standard high-rigidity internal 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\u003eQ\u003c\/strong\u003e - 180mm Industrial Standard Total Tool Core Length (Precision deep-reach standard specification)\u003c\/div\u003e\n\u003cdiv style=\"display: block; margin-bottom: 6px; border: 1px solid #47479F; padding: 8px; border-radius: 4px; background: #f0f2f5; color: #333333;\"\u003e\n\u003cstrong\u003eW\u003c\/strong\u003e - \u003cstrong\u003eDouble Clamping Clamping Method\u003c\/strong\u003e (Dual force system: Top clamp plate + center pulling lever pin for absolute zero-play indexable lock)\u003c\/div\u003e\n\u003cdiv style=\"display: block; margin-bottom: 6px; border: 1px solid #47479F; padding: 8px; border-radius: 4px; background: #f0f2f5; color: #333333;\"\u003e\n\u003cstrong\u003eL\u003c\/strong\u003e - \u003cstrong\u003e95° Trigon Shape Pocket Seating\u003c\/strong\u003e (The 5th position identifier matching 95-degree negative double-sided WNMG shapes)\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 Negative Insert Clearance Angle (Provides high edge strength and unlocks double-sided indexable cutting edges)\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 - \u003cstrong\u003eRight-Hand Tool Cutting Rotation Direction\u003c\/strong\u003e (Standard forward M03 internal turning toolpath setup)\u003c\/div\u003e\n\u003cdiv style=\"display: block; border: 1px solid #47479F; padding: 8px; border-radius: 4px; background: #ffffff;\"\u003e\n\u003cstrong\u003e08\u003c\/strong\u003e - Accommodates Standard 8mm Inscribed Circle Cutting Edge Length Inserts (WNMG 080404 \/ WNMG 080408)\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;\"\u003eOperating reverse roughing 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=WNMG0804\" target=\"_blank\" rel=\"noopener\"\u003eSwitch to the Mirror S16Q-SWLNL08 (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.

The W-type double clamping configuration anchors negative WNMG inserts via a center wedge lever pulling pin plus a solid structural top clamp bridge.
