Forged from premium vacuum-hardened structural alloy steel, this ultra-robust 32mm diameter shank tool holder body features an extended length profile (T-type, 300mm total length) designed to absorb massive torsional cutting forces during deep cantilever overhang passes.

When paired with an 80° positive rhombic insert integrating a robust multi-stage chipbreaker groove, this tooling assembly actively breaks tough structural steel swarf into compact, manageable helical segments. This advanced mechanical chip control ensures loose chips are forced outward through the large bore neck via flooded coolant pressure, entirely eliminating the risk of continuous stringy chip nesting that causes micro-cracks in carbide edges and spoils expensive workpiece dimensional limits.\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: S32T-SCLCL12\u003c\/h3\u003e\n\u003cdiv style=\"display: flex; flex-wrap: wrap; gap: 10px; font-family: monospace; font-size: 13px; margin-top: 12px;\"\u003e\n\u003cdiv style=\"flex: 1; min-width: 130px; border: 1px solid #cccccc; padding: 8px; border-radius: 4px; text-align: center; background: #ffffff;\"\u003e\n\u003cstrong\u003eS\u003c\/strong\u003e\u003cbr\u003e\u003cspan style=\"font-size: 11px; color: #666;\"\u003eSolid Alloy Steel Core\u003c\/span\u003e\n\u003c\/div\u003e\n\u003cdiv style=\"flex: 1; min-width: 130px; border: 1px solid #cccccc; padding: 8px; border-radius: 4px; text-align: center; background: #ffffff;\"\u003e\n\u003cstrong\u003e32\u003c\/strong\u003e\u003cbr\u003e\u003cspan style=\"font-size: 11px; color: #47479f; font-weight: bold;\"\u003e32mm Shank Dia.\u003c\/span\u003e\n\u003c\/div\u003e\n\u003cdiv style=\"flex: 1; min-width: 130px; border: 1px solid #cccccc; padding: 8px; border-radius: 4px; text-align: center; background: #ffffff;\"\u003e\n\u003cstrong\u003eT\u003c\/strong\u003e\u003cbr\u003e\u003cspan style=\"font-size: 11px; color: #47479f; font-weight: bold;\"\u003e300mm Total Length\u003c\/span\u003e\n\u003c\/div\u003e\n\u003cdiv style=\"flex: 1; min-width: 130px; border: 1px solid #cccccc; padding: 8px; border-radius: 4px; text-align: center; background: #ffffff;\"\u003e\n\u003cstrong\u003eS\u003c\/strong\u003e\u003cbr\u003e\u003cspan style=\"font-size: 11px; color: #666;\"\u003eScrew Clamping System\u003c\/span\u003e\n\u003c\/div\u003e\n\u003cdiv style=\"flex: 1; min-width: 130px; border: 1px solid #cccccc; padding: 8px; border-radius: 4px; text-align: center; background: #ffffff;\"\u003e\n\u003cstrong\u003eC\u003c\/strong\u003e\u003cbr\u003e\u003cspan style=\"font-size: 11px; color: #666;\"\u003e80° Rhombic Insert\u003c\/span\u003e\n\u003c\/div\u003e\n\u003cdiv style=\"flex: 1; min-width: 130px; border: 1px solid #cccccc; padding: 8px; border-radius: 4px; text-align: center; background: #ffffff;\"\u003e\n\u003cstrong\u003eL\u003c\/strong\u003e\u003cbr\u003e\u003cspan style=\"font-size: 11px; color: #666;\"\u003e95° Approach Angle\u003c\/span\u003e\n\u003c\/div\u003e\n\u003cdiv style=\"flex: 1; min-width: 130px; border: 1px solid #cccccc; padding: 8px; border-radius: 4px; text-align: center; background: #ffffff;\"\u003e\n\u003cstrong\u003eC\u003c\/strong\u003e\u003cbr\u003e\u003cspan style=\"font-size: 11px; color: #666;\"\u003e7° Insert Relief Angle\u003c\/span\u003e\n\u003c\/div\u003e\n\u003cdiv style=\"flex: 1; min-width: 130px; border: 1px solid #cccccc; padding: 8px; border-radius: 4px; text-align: center; background: #47479F; color: #ffffff;\"\u003e\n\u003cstrong\u003eL\u003c\/strong\u003e\u003cbr\u003e\u003cspan style=\"font-size: 11px; color: #ffffff; font-weight: bold;\"\u003eLeft Hand Cutting Direction\u003c\/span\u003e\n\u003c\/div\u003e\n\u003cdiv style=\"flex: 1; min-width: 130px; border: 1px solid #cccccc; padding: 8px; border-radius: 4px; text-align: center; background: #47479F; color: #ffffff;\"\u003e\n\u003cstrong\u003e12\u003c\/strong\u003e\u003cbr\u003e\u003cspan style=\"font-size: 11px; color: #ffffff; font-weight: bold;\"\u003e12mm Cutting Edge (CCMT1204)\u003c\/span\u003e\n\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 Standard Clockwise Spindle Cycles or Main Turret Front Boring Overhangs?\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=CCMT1204\" target=\"_blank\" rel=\"noopener\"\u003eSwitch to the Mirror S32T-SCLCR12 (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;\"\u003e2.
