ZCC.CT RCKT2006MO-DM YBM251 Milling Insert
The Professional Solution for Stainless Steel & Heat-Resistant Alloys
Product Overview
The ZCC.CT RCKT2006MO-DM in YBM251 grade is a high-performance 20mm round insert engineered specifically for ISO M (Stainless Steel) and ISO S (Superalloys). The YBM251 grade features a specialized CVD coating with a smooth surface that resists built-up edge (BUE)—a common failure in stainless machining. The DM (Medium-Duty) chipbreaker is optimized with a sharp yet stable rake angle to slice through gummy materials while maintaining the structural integrity required for 20mm large-diameter milling.
Key Advantages
- [✓] Advanced YBM251 Substrate: A perfect balance of toughness and thermal deformation resistance for difficult-to-cut materials.
- [✓] Anti-Adhesion Coating: Specialized CVD technology minimizes "sticking" on the cutting edge, extending tool life in 304/316 stainless.
- [✓] Large 20mm Stability: The RCKT2006 size allows for massive metal removal rates and deep copy milling operations.

What Our Customers Say
"The YBM251 is my top choice for 316L. The RCKT20 size removes material so fast."
— James P., USA 🇺🇸"Sehr gute Qualität für Edelstahl. Standzeit ist im Vergleich zu Wettbewerbern top."
— Dieter B., Germany 🇩🇪"Ottima resistenza all'usura. Usata su acciaio inox austenitico con ottimi risultati."
— Lorenzo M., Italy 🇮🇹"Consistent tool life. Best price/performance ratio in the Japanese market."
— Sato K., Japan 🇯🇵FAQ
Q: Should I use coolant with YBM251?
A: For stainless steel, high-pressure coolant is highly recommended to flush chips and prevent thermal cracks on the cutting edge.
Q: Is the 20mm insert better than the 16mm?
A: The 20mm size (RCKT2006) offers more mass and a larger radius, allowing for much deeper cuts and higher stability in heavy profiling.
Q: Can YBM251 machine regular steel?
A: It can, but the YBC series is more economical and efficient for standard P-class carbon steel. YBM is a premium grade for difficult alloys.

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.
Our automatic quantity discount is 6% off for 2–9 items and 12% off for 10 or more items, based on the total product quantity in the cart. Other offers may not combine with this discount; check the applicable offer conditions.
