BEYOND SVJCL1212H11 External Turning Tool Holder
Product Overview
"Which 12mm left-hand holder is best for high-precision 93° profiling and finish turning on small-diameter stainless steel parts?"
The BEYOND SVJCL1212H11 is a professional-grade, left-hand (LH) external turning tool holder with a 12x12mm shank. Engineered for the 35° rhombic VCMT 1103 or VCGT 1103 carbide inserts, it is the ideal choice for precision profiling where space is limited. The 93° approach angle provides excellent clearance for contouring, making it a staple for Swiss-type lathes and small CNC centers machining steel, stainless steel, and non-ferrous materials.
Key Features
- ✔Quenched Alloy Steel: Body hardness of HRC 42-45 ensures superior rigidity and reduced vibration.
- ✔93° Precision Lead: Designed specifically for profiling and back-turning with zero rubbing.
- ✔Advanced S-Type Clamping: Optimized screw-down mechanism for fast insert indexing and clear chip evacuation.
- ✔Compact Versatility: Ideal for precision medical, aerospace, and electronics hardware manufacturing.

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.
