Forged from high-tensile pre-hardened structural alloy steel, this standard 16mm diameter shank tool holder body features a Q-type length profile (180mm total length), providing the optimal balance of rigidity and clearance required to eliminate harmonic vibrations during internal turning cycles. Engineered to maximize accuracy in tight boundaries, it pairs a universal 16mm shank with a micro-precision machined pocket that securely holds tight-tolerance \u003cstrong\u003eCCMT 09T3-- indexable carbide inserts\u003c\/strong\u003e or highly polished \u003cstrong\u003eCCGT 09T3-- non-ferrous aluminum inserts\u003c\/strong\u003e.\u003c\/p\u003e\n\u003cp\u003eAchieving a flawless, scratch-free surface finish during internal blind-hole boring depends entirely on chipbreaker geometry and evacuation dynamics. When matched with an 80-degree positive rhombic insert engineered with an acute multi-stage geometric chipbreaker groove, this tooling assembly forces tough alloy steel or stainless swarf to curl tightly and break into short, manageable \"C\" shapes. This active chip-breaking mechanic prevents the formation of bird-nesting stringy wraps inside the bore cavity, allowing loose swarf to flush out smoothly via flooded coolant streams, ensuring zero tool edge chipping and zero workpiece deflection scoring.\u003c\/p\u003e\n\u003cdiv style=\"border: 2px solid #47479F; border-radius: 6px; padding: 20px; margin: 25px 0; background-color: #fbfbfe; page-break-inside: avoid;\"\u003e\n\u003ch3 style=\"margin-top: 0; color: #47479f; font-size: 16px; border-bottom: 1px solid #e0e0e0; padding-bottom: 8px;\"\u003eModel Nomenclature Decoder: S16Q-SCLCL09\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\u003e16\u003c\/strong\u003e - 16mm Standard Shank Diameter (Metric Configuration)\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 Compact-Reach Tool Overall Length 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\u003eS\u003c\/strong\u003e - High-Torque Screw Clamping Retention Mechanism\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\u003eC\u003c\/strong\u003e - 80° Rhombic Geometric Insert Shape Pocket Alignment\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 Clearance Lead Side Angle\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\u003eC\u003c\/strong\u003e - 7° Insert Normal Relief Clearance Angle\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\u003eL\u003c\/strong\u003e - Left Hand Cutting Rotation Tool Direction\u003c\/div\u003e\n\u003cdiv style=\"display: block; border: 1px solid #47479F; padding: 8px; border-radius: 4px; background: #47479F; color: #ffffff;\"\u003e\n\u003cstrong\u003e09\u003c\/strong\u003e - 9mm Cutting Insert Inscribed Edge Configuration (Fits CCMT09T3)\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; page-break-inside: avoid;\"\u003e\n\u003cp style=\"margin: 0 0 10px 0; font-weight: bold; font-size: 16px;\"\u003eRunning Conventional Clockwise Spindle Passes or Standard Front Turret Blocks?\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=CCMT09T3\" target=\"_blank\" rel=\"noopener\"\u003eSwitch to the Mirror S16Q-SCLCR09 (Right Hand) Tool Holder → \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; page-break-after: avoid;\"\u003e2.
