Alex H. (USA) - The 20mm shank fits my Haas perfectly. The 93 degree angle is essential for my contouring work.
"Hervorragende Qualität"
Klaus B. (Germany) - Precision pocket design. The VBMT 16 insert sits extremely tight, even under heavy finishing loads.
"Great Surface Finish"
Marco S. (Italy) - Very reliable tool for stainless profiling. Vibrations are well-dampened for a 20mm shank.
"Consistent Quality"
T. Sato (Japan) - Standard ISO tolerances are met. Good value for money compared to bigger brands.
Industrial Support FAQ
A: Yes, the 93° lead angle allows for both longitudinal turning and facing toward a clean 90-degree shoulder.
A: The size 16 insert is more robust and thicker than the size 11, making it better for medium finishing where you might encounter slightly heavier cuts.
A: Yes, every BEYOND tool holder comes complete with the high-tensile locking screw and the corresponding Torx wrench.
Grade Comparison Tip: Use BEYOND BY815 for general steel applications or BYM25 for heat-resistant alloys.
Equivalent Models: Sandvik SVUBL-2020K16, Kennametal SVUBL2020K16, Iscar SVUBL-2020-K16.
Troubleshooting: If chipping occurs, ensure the coolant is directed at the cutting tip and check for tool center height alignment.

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.
