The 20mm shank is the industry standard for medium-sized CNC lathes and turret stations. It excels in longitudinal turning and profiling where a neutral hand provides the versatility to cut in both directions depending on the turret setup. Perfectly compatible with machines from Haas, Mazak, Doosan, DMG Mori, and Okuma.
Verified Machinist Feedback
"Excellent for Profiling"
James K. (USA) - The 20mm shank is very rigid on my Haas ST-10. Neutral hand makes it very versatile.
"Sehr gute Qualität"
Oliver B. (Germany) - Solid fitment for VBMT inserts. Great value for the price compared to big brands.
"Versatile and Durable"
Marco V. (Italy) - Good rust resistance and the center height was dead on. Profiling finish is mirror-like.
"Industrial Standard"
Kenji H. (Japan) - Standard ISO dimensions. Works well for our production line.
Industrial Support FAQ
A: As a neutral (N) hand holder, the tool can be oriented in various ways, but it is primarily used for centered profiling and facing depending on your turret rotation.
A: Yes, every BEYOND holder includes the correct insert screw and Torx wrench in the box.
A: The holder itself is made of high-quality alloy steel. The workpiece compatibility (Steel, Stainless, etc.) depends on the carbide insert grade you choose to install.
Grade Comparison: Pair with BEYOND BY815 for multi-material steel or BYM25 for dedicated stainless steel turning.
Equivalent Models: Sandvik SVVBN-2020K16, Kennametal SVVBN2020K16, Iscar SVVBN-2020-K16.
Troubleshooting: If vibration occurs, check tool overhang (maintain 3x shank height max) and verify 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.
