Forged from premium vacuum-degassed structural alloy steel and treated with an advanced oil-quenching heat cycle, this solid 32mm shank boasts an optimized core hardness of HRC 42-47. This robust structural mass successfully neutralizes severe harmonic micro-chatter over deep-hole extensions up to 4xD (120mm). Designed explicitly to facilitate unhindered chip evacuation during reverse paths, the 5-axis precision-machined pocket holds 35-degree positive rhombic \u003cstrong\u003eVBMT 1604\u003c\/strong\u003e or \u003cstrong\u003eVCGT 1604\u003c\/strong\u003e inserts. By mounting a substantial 16mm indexable insert onto a heavy 32mm body, this assembly provides the sheer mechanical deflection resistance required to prevent taper across deep-bore chambers. Compatible VBMT inserts utilize dual-stage molded chipbreakers to curl stringy alloy steels into safe, tight \"C\" segments, while polished VCGT inserts feature ultra-sharp, high-rake cutting zones to eliminate built-up edge (BUE) on sticky non-ferrous aluminum. The specialized SVZBR geometry shifts the heavy radial cutting forces axially back into the lathe turret, guaranteeing superior concentricity and an excellent surface finish.\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: 19px; margin-top: 30px; font-weight: bold;\"\u003e2.

If chatter persists at long overhangs, reduce the insert nose radius from a 0.8mm (VBMT 160408) down to a 0.4mm (VBMT 160404) or select a sharp high-rake ground VCGT insert. Reducing the nose contact area shifts the radial pressure into axial force, focusing structural load back along the 32mm steel core to secure absolute cutting stability.\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c!-- Bottom Grade Comparison \u0026 Workpiece Material Matrix Tip --\u003e\n\u003cdiv style=\"background-color: #333333; color: #ffffff; padding: 18px; border-radius: 6px; font-size: 13px; text-align: justify; line-height: 1.6;\"\u003e\n\u003cstrong\u003eMachinist Setup Tip (Workpiece Material Matrix Alignment):\u003c\/strong\u003e When executing deep internal back-boring with the S32T-SVZBR16, ensure the tool tip center-height is calibrated within ±0.02mm of the spindle axis. Because the VBMT 1604 insert features a built-in 5° positive clearance angle, setting the tool even slightly above the centerline reduces the functional clearance toward zero. This causes the insert flank to rub intensely against the tight internal radius of the workpiece, creating destructive micro-chatter, fracturing the delicate 16mm carbide edge, and damaging surface integrity. Ensure high-pressure coolant lines are focused directly into the pocket channel to continuously clear out broken chips.\u003c\/div\u003e\n\u003c\/div\u003e","brand":"BEYOND","offers":[{"title":"Default Title","offer_id":43631830270124,"sku":"S32T-SVZBR16","price":56.44,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0592\/7328\/1708\/files\/BEYOND_S32T-SVZBR16_heavy_duty_internal_reverse_pull_boring_bar_CNC_lathe_tool_holder_for_VBMT_160404_160408_indexable_profiling_inserts.jpg?v=1779676114","url":"https:\/\/cnchome-beyond.com\/products\/beyond-s32t-svzbr16-boring-bar-internal-back-boring-tool-holder","provider":"CNCHome-Beyond","version":"1.0","type":"link"}
