Forged from high-tensile structural alloy steel and multi-stage quenched to HRC 42-47, this solid 25mm shank provides massive structural stiffness to suppress micro-vibrations across extended overhang lengths up to 4xD (100mm). Superbly optimized for intricate copy turning paths, the precision 5-axis machined pocket features an exact seating alignment designed exclusively to hold 35-degree positive rhombic \u003cstrong\u003eVBMT 1604\u003c\/strong\u003e or \u003cstrong\u003eVCGT 1604\u003c\/strong\u003e turning inserts.

Because the 35° VBMT 1604 insert operates in a tight 32mm internal bore, setting the tool above center compromises functional flank clearance, causing the insert body to rub against the internal radius. This error leads to rapid insert edge failure, internal step chatter marks, and poor dimensional control.\u003c\/div\u003e\n\u003c\/div\u003e","brand":"BEYOND","offers":[{"title":"Default Title","offer_id":43622408945836,"sku":"S25S-SVWBR16","price":33.31,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0592\/7328\/1708\/files\/BEYOND_S25S-SVWBR16_indexable_internal_95_degree_profiling_boring_bar_right_hand_CNC_lathe_tool_holder_for_VBMT_160404_VBMT_160408_inserts.jpg?v=1779690397","url":"https:\/\/cnchome-beyond.com\/products\/s25s-svwbr16-beyond-boring-bar-cnc-internal-turning-holder","provider":"CNCHome-Beyond","version":"1.0","type":"link"}
