Machined from premium quenched alloy steel, this compact 12mm diameter tool holder combines an optimized structural layout with high dynamic rigidity to counter bending stresses and suppress high-frequency harmonic vibration in deep bores up to 4xD overhang. Specifically designed to pocket positive 80-degree trigon indexable inserts—such as the \u003cstrong\u003eWCMT 0402\u003c\/strong\u003e series—the precision-ground pocket structure leverages the 3-corner design and 7-degree positive relief angle of the insert to significantly lower cutting resistance while maximizing chip evacuation performance. By firmly anchoring the insert via a low-profile Torx screw lock system, this bar ensures continuous chip fracturing, exact dimensional repeatability, and smooth surface finishes inside narrow workpiece paths.\u003c\/p\u003e\n\u003c!-- Section 2: Key Features --\u003e\n\u003ch2 style=\"color: #47479f; border-bottom: 2px solid #47479F; padding-bottom: 8px; font-size: 20px; margin-top: 30px; font-weight: bold;\"\u003e2.
