BEYOND S16Q-SVQBL11 Indexable Internal Left-Hand Boring Bar (Fits VBMT 1103)
1. Product Overview
"Which 16mm left-hand boring bar provides the best vibration dampening and clearance for deep internal profiling with VBMT 1103 inserts?"
The BEYOND S16Q-SVQBL11 is a precision-engineered internal boring bar for industrial CNC turning applications. Featuring a high-rigidity steel shank hardened to HRC 42-47, it minimizes harmonic chatter in deep-hole operations. The 107.5° approach angle (SVQBL geometry) is specifically optimized for back-boring and profile copying, ensuring excellent tool-body clearance without sacrificing structural integrity. Designed to house standard 35° positive rhombic VBMT 1103 inserts, this tool guarantees dimensional accuracy and superior surface finish.
2. Key Features
- Rigid 16mm Steel Shank: Minimizes deflection in medium-reach internal applications.
- 107.5° Lead Angle: Perfect for relief pocketing and reverse-profile cycles.
- Precision Screw-Locking: Provides secure, repeatable indexing of the insert.
- Industrial Black Oxide: Corrosion-resistant coating for long-term reliability in coolant-heavy environments.

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.
