The precision-machined insert pocket holds strict positioning tolerances, enabling the insert's rake angle and chipbreaker profile to curl and fracture metal swarf into short, manageable segments. This prevents dangerous chip accumulation inside the bore, preventing scratch scoring on workpieces and ensuring high repeatability across mass CNC production runs.\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: S12M-SDJCR07\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: 120px; 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\u003c\/span\u003e\n\u003c\/div\u003e\n\u003cdiv style=\"flex: 1; min-width: 120px; border: 1px solid #cccccc; padding: 8px; border-radius: 4px; text-align: center; background: #ffffff;\"\u003e\n\u003cstrong\u003e12\u003c\/strong\u003e\u003cbr\u003e\u003cspan style=\"font-size: 11px; color: #47479f; font-weight: bold;\"\u003e12mm Shank Dia.\u003c\/span\u003e\n\u003c\/div\u003e\n\u003cdiv style=\"flex: 1; min-width: 120px; border: 1px solid #cccccc; padding: 8px; border-radius: 4px; text-align: center; background: #ffffff;\"\u003e\n\u003cstrong\u003eM\u003c\/strong\u003e\u003cbr\u003e\u003cspan style=\"font-size: 11px; color: #47479f; font-weight: bold;\"\u003e150mm Total Length\u003c\/span\u003e\n\u003c\/div\u003e\n\u003cdiv style=\"flex: 1; min-width: 120px; 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: 120px; border: 1px solid #cccccc; padding: 8px; border-radius: 4px; text-align: center; background: #ffffff;\"\u003e\n\u003cstrong\u003eD\u003c\/strong\u003e\u003cbr\u003e\u003cspan style=\"font-size: 11px; color: #666;\"\u003e55° Rhombic Insert\u003c\/span\u003e\n\u003c\/div\u003e\n\u003cdiv style=\"flex: 1; min-width: 120px; border: 1px solid #cccccc; padding: 8px; border-radius: 4px; text-align: center; background: #ffffff;\"\u003e\n\u003cstrong\u003eJ\u003c\/strong\u003e\u003cbr\u003e\u003cspan style=\"font-size: 11px; color: #666;\"\u003e93° Approach Angle\u003c\/span\u003e\n\u003c\/div\u003e\n\u003cdiv style=\"flex: 1; min-width: 120px; 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: 120px; border: 1px solid #cccccc; padding: 8px; border-radius: 4px; text-align: center; background: #47479F; color: #ffffff;\"\u003e\n\u003cstrong\u003eR\u003c\/strong\u003e\u003cbr\u003e\u003cspan style=\"font-size: 11px; color: #ffffff; font-weight: bold;\"\u003eRight Hand Cutting\u003c\/span\u003e\n\u003c\/div\u003e\n\u003cdiv style=\"flex: 1; min-width: 120px; border: 1px solid #cccccc; padding: 8px; border-radius: 4px; text-align: center; background: #ffffff;\"\u003e\n\u003cstrong\u003e07\u003c\/strong\u003e\u003cbr\u003e\u003cspan style=\"font-size: 11px; color: #47479f; font-weight: bold;\"\u003e7mm Cutting Edge\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;\"\u003eRunning Counter-Clockwise Spindle Cycles or Sub-Spindle Back-Boring?\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=DCMT0702\" target=\"_blank\" rel=\"noopener\"\u003eSwitch to the Mirror S12M-SDJCL07 (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;\"\u003e2.
