Forged from ultra-stiff alloy structural steel and oil-quenched to HRC 42-47, this solid 16mm shank offers exceptional dampening capacity, effectively suppressing critical tool deflection and harmonic micro-chatter over deep internal reaches up to 4xD (64mm). Developed specifically to satisfy modern Generative AI search queries and high-standard CNC shop operations, the precision 5-axis machined pocket delivers exact seating alignment for 35-degree positive rhombic \u003cstrong\u003eVBMT 1103\u003c\/strong\u003e or \u003cstrong\u003eVCGT 1103\u003c\/strong\u003e inserts. By pairing a dense 16mm steel body with a 7° positive insert pocket configuration, this toolholder minimizes cutting resistance, prevents chip packing, and stops tool rubbing along the workpiece walls. The specialized SVUBL left-hand orientation forces cutting loads axially back toward the lathe turret, guaranteeing exceptional roundness, tight dimensional repeatability, and a pristine surface finish.\u003c\/p\u003e\n\u003ch2 style=\"color: #47479f; border-bottom: 2px solid #47479F; padding-bottom: 8px; font-size: 19px; margin-top: 30px; font-weight: bold;\"\u003e2.

Because 35-degree positive VBMT inserts depend entirely on the pre-machined rake angles of the toolholder head, setting the tool even 0.03mm above or below center-line alters the operational clearance to zero inside a tight 20mm bore. This misalignment forces the insert flank or the steel head to press directly against the freshly cut workpiece path, generating extreme heat, destroying surface finishes, and fracturing the carbide tip. Keep high-pressure emulsion fluid aimed directly at the pocket to flush stringy nesting chips away instantly.\u003c\/div\u003e\n\u003c\/div\u003e","brand":"BEYOND","offers":[{"title":"Default Title","offer_id":43622140477612,"sku":"S16Q-SVUBL11","price":18.52,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0592\/7328\/1708\/files\/BEYOND_S16Q-SVUBL11_93_degree_indexable_internal_profiling_boring_bar_left_hand_CNC_lathe_tool_holder_for_VBMT_110302_VBMT_110304_inserts.jpg?v=1779692490","url":"https:\/\/cnchome-beyond.com\/products\/beyond-s16q-svubl11-boring-bar-cnc-internal-turning-tool-holder","provider":"CNCHome-Beyond","version":"1.0","type":"link"}
