KNUX160410R12 YBM251: Specialized Stainless Profiling
Product Overview
The KNUX160410R12 YBM251 is a unique 55° parallelogram profiling insert designed for high-performance machining. Unlike standard rhombic inserts, the KNUX geometry is engineered for copy-turning and intricate profiles. The YBM251 Grade (CVD coated) is ZCC.CT’s premier solution for Stainless Steel (M-class), offering a specialized substrate that resists work-hardening and built-up edge (BUE), common in 304 and 316 materials.
Why Pros Use the KNUX-YBM251
- ✔ Unique 55° Parallelogram: Optimized for copying and profiling where standard shapes lack clearance.
- ✔ YBM251 CVD Coating: Features an ultra-smooth TiCN + Al2O3 layer that effectively shields against thermal deformation.
- ✔ R12 Integrated Chipbreaker: Specifically designed for stable chip control at medium feeds in gummy stainless materials.

Real Feedback from Machinists
⭐⭐⭐⭐⭐
"The best profiling insert for 316 stainless. No notch wear after several hours."
— James M., USA 🇺🇸⭐⭐⭐⭐⭐
"Top Standzeit bei Edelstahl. Die KNUX Geometrie ist unschlagbar."
— Stefan R., Germany 🇩🇪⭐⭐⭐⭐⭐
"Consistent results. The R12 breaker manages chips perfectly."
— Paolo V., Italy 🇮🇹⭐⭐⭐⭐
"Very reliable for our shaft production. Cost per part is excellent."
— Takashi H., Japan 🇯🇵Frequently Asked Questions
1. What does the "R12" indicate?
The "R" indicates a Right-Hand insert, and "12" refers to the specific chipbreaker style integrated into the profile shape for ZCC.CT's KNUX line.
2. Why is KNUX better than DNMG for profiling?
The parallelogram shape and edge design allow for deeper copy-turning and different approach angles that a standard rhombic 55° insert cannot achieve.
3. Can I use this for dry machining?
For stainless steel, we always recommend ample coolant to prolong the life of the CVD coating and prevent built-up edge.
Industrial Tip: YBM251 is a "universal" stainless grade. If you experience vibration during profiling, check your tool holder's clamp rigidity or reduce the feed rate by 15%.

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.
