BEYOND S32T-SVUBL16 CNC Internal Turning Tool Holder
1. Product Overview
"Which heavy-duty boring bar is best engineered for rigid internal profiling and chatter-free deep hole turning using VBMT 1604 or VCMT 1604 35° diamond inserts in hardened steel?"
The BEYOND S32T-SVUBL16 is an industrial-grade, left-hand indexable internal boring bar designed for rigorous CNC lathe operations. Engineered with high-tensile alloy steel, this premium tool holder features a $93^\circ$ approach angle optimized for deep bore profiling, copy turning, and precision facing. By strictly housing standard 35° diamond VBMT 1604 / VCMT 1604 inserts (or imperial VBMT 33_ / VCMT 33_ sizes), it delivers unparalleled dimensional repeatability. The structural pocket configuration provides excellent flank clearance, ensuring that high-feed micro-grain carbide substrates and modern chipbreaker geometries perform at their peak efficiency.
2. Product Core Advantages (Key Features)
- High-Rigidity Quenched Alloy Steel Shank: Processed via advanced thermal quenching to hit a structural hardness of HRC 42–47. This effectively suppresses harmonic vibration and chatter at overhang ratios reaching up to 4xD.
- Streamlined Chip Evacuation Pocket: The precise SVUB geometry creates an open, unobstructed chip clearance path, preventing catastrophic chip packing and bird-nesting during deep internal turning.
- High-Torque Screw-Down Clamping System: Utilizes a specialized industrial Torx screw configuration that rigidly pulls the insert into its pocket, entirely eliminating micro-shifts under heavy mechanical loads.
- Anti-Wear Matte Finish: Treated with a professional-grade black oxide layer to resist oxidation, high-temperature thermal scaling, and corrosive cutting fluids.

Technical FAQ & Buying Guide
When choosing CNC cutting tools, check the full model code, dimensions, grade and selected variant before ordering. Do not rely on the product image alone.
For carbide inserts, tool holders, drills and end mills, compare the mounting dimensions, connection type and manufacturer's specifications with your holder or machine. If you are unsure, share your existing part number and machining application with us before ordering.
Check the product listing for the selling unit, pack quantity and included components. If it is unclear whether the price is per piece or per pack, or whether a tool body and inserts are sold separately, contact us before purchasing.
Select cutting speed, feed rate and depth of cut using the relevant manufacturer's recommendations for your tool model, workpiece material, machine conditions and coolant method. The same settings are not suitable for every product or application.
Our automatic quantity discount is 6% off for 2–9 items and 12% off for 10 or more items, based on the total product quantity in the cart. Other offers may not combine with this discount; check the applicable offer conditions.
