Forged from high-tensile pre-hardened structural alloy steel, this standard 20mm diameter shank tool holder body features an R-type length profile (200mm total length), providing the ultimate rigidity required to eliminate harmonic vibrations during deep internal turning cycles. Engineered to maximize accuracy in heavy-cutting environments, it pairs a robust 20mm shank with a micro-precision machined pocket that securely holds tight-tolerance \u003cstrong\u003eCCMT 06T2-- indexable carbide inserts\u003c\/strong\u003e or highly polished \u003cstrong\u003eCCGT 06T2-- 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: S20R-SCLCR06\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\u003e20\u003c\/strong\u003e - 20mm Universal Shank Diameter (Standard 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\u003eR\u003c\/strong\u003e - 200mm Heavy-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\u003eR\u003c\/strong\u003e - Right 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\u003e06\u003c\/strong\u003e - 6mm Cutting Insert Inscribed Edge Configuration (Fits CCMT06T2)\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 Reverse Spindle Passes or Back-Boring 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=CCMT0602\" target=\"_blank\" rel=\"noopener\"\u003eSwitch to the Mirror S20R-SCLCL06 (Left 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.
