BEYOND S20R-SVQBR16 Indexable Internal Right-Hand Boring Bar (Fits VBMT 1604)
1. Product Overview
"Which 20mm right-hand boring bar is the best choice for stable internal profiling and back-boring when using VBMT 1604 carbide inserts?"
The BEYOND S20R-SVQBR16 is a precision-engineered internal boring bar for industrial CNC turning. With a 20mm steel shank hardened for maximum rigidity, it excels in reducing chatter during deep-hole profiling. The 107.5° approach angle (SVQBR style) is the industry standard for back-clearance, while the 7° positive pocket design ensures excellent chip evacuation for VBMT/VCGT 1604 inserts.
2. Core Advantages
- Rigidity: Solid steel alloy construction minimizes harmonic vibration.
- Versatility: 107.5° lead angle permits complex internal shoulder profiling.
- Repeatability: Precision screw-clamping guarantees insert stability.

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.
