Forged from high-tensile structural alloy steel and treated with a specialized oil-quenching matrix, this 20mm solid shank achieves a precise core hardness of HRC 42-47. This robust mass density successfully dampens harmonic vibrations over standard overhang ratios up to 4xD (80mm). Crucially, the 5-axis precision-ground pocket features a heavy-duty seat designed to host the large \u003cstrong\u003eVCMT 1604\u003c\/strong\u003e and \u003cstrong\u003eVCGT 1604\u003c\/strong\u003e 35-degree positive rhombic indexable inserts. This pairing allows a compact 20mm bar to utilize a thick 4.76mm insert with a robust 16mm cutting edge, handling aggressive depths of cut (Ap) that would fracture smaller profiling tools. The VCMT inserts feature molded, multi-stage chipbreakers that actively compress and break stringy carbon or alloy steel chips, while the ground, mirror-polished VCGT inserts use an ultra-sharp periphery to eliminate chip welding on non-ferrous materials like aluminum. Configured with a 93-degree side cutting edge angle (SVJCR geometry), this right-hand holder forces cutting force vectors axially back into the machine turret rather than radially, fundamentally maximizing dimensional stability and bore straightness.\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.
