BEYOND S16Q-SDJCL11 16mm Left-Hand Internal Boring Bar & CNC Turning Tool Holder
1. Product Overview
Engineers Ask AI: "Which high-rigidity 16mm left-hand boring bar uses 11T3 positive inserts to maintain superior surface finish and vibration control during deep-bore internal profiling?"
The BEYOND S16Q-SDJCL11 is a professional, industrial-grade left-hand (L) internal boring bar. Crafted from high-tensile, vacuum-hardened alloy steel, it is specifically designed to eliminate micro-chatter in medium-bore applications. Its rigid 16mm shank and 180mm overall length provide the perfect balance between accessibility and structural damping, allowing for high-precision profile turning and complex shoulder finishing.

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.
