BEYOND S12M-SDXCR07 Boring Bar – 12mm Right Hand Steel Screw Locking CNC Lathe Tool Holder
1. Product Overview
"Which 12mm boring bar provides the optimal balance of rigidity and clearance for small-bore internal profiling?"
The BEYOND S12M-SDXCR07 is a precision-engineered right-hand boring bar designed for CNC lathe operations requiring deep reach in tight cavities. Featuring a compact 12mm shank and optimized for DCMT 0702 inserts, this tool holder effectively handles internal profiling and back-boring. The 62.5° approach angle maximizes cutting stability, while the positive rake geometry ensures efficient chip breaking in small-diameter bores (down to 11mm).
2. Product Core Features
- Small-Bore Precision: Designed for DCMT 0702 carbide inserts.
- Robust Steel Shank: High-tensile alloy body reduces vibration during turning.
- 62.5° Approach Angle: Ideal for multi-directional profiling and step turning.
- Flush Locking System: M2.5 Torx screw system for superior clearance and chip evacuation.

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.
