N-Series Low Speed Oil-Cooling Soft Cutting Hobs
Redefine economy in soft gear manufacturing. The Nobeve N-Series combines high-toughness die-cast alloy with Oerlikon Balzers PVD coatings to deliver the perfect balance of durability and budget.
Toughness-Optimized Substrate
Sourced from quality domestic suppliers, this ordinary die-cast tungsten cobalt alloy is engineered to withstand the mechanical vibrations common in older hobbing machines. It resists the chipping that often plagues harder carbide grades at lower speeds.
Premium Friction Control
Despite being our economical line, we do not compromise on surface treatment. We feature Oerlikon Balzers BALINIT® ALCRONA PRO to ensure low friction coefficients in oil, preventing the "built-up edge" (BUE) issues common when cutting sticky, soft materials.
Smart Cost-Efficiency
Delivers Nobeve’s consistent precision standards without the premium cost of high-speed technology, offering an optimal ROI for low-to-medium volume standard gear production.
Universal Speed Range
Calibrated for a versatile operating window of 60m/min - 150m/min. This allows the N-Series to run effectively on both slow traditional hobbing machines and modern high-speed CNC machines, providing flexibility for your shop
Expert Technical FAQ
Frequently Asked Questions
Is the N-Series made from the same material as the K-Series?
No. To provide the most cost-effective solution, the N-Series uses ordinary die-cast tungsten cobalt alloy , whereas the K-Series uses imported German Konrad Friedrichs solid rods. This difference allows the N-Series to be much more affordable while still offering excellent performance for soft materials (≤HRC 30) .
Can this hob run dry (without oil)?
No, the N-Series is strictly for Oil-Cooling machining environments . The substrate and the standard BALINIT® ALCRONA PRO coating rely on the lubricity and cooling effect of oil to maintain edge integrity. Running dry may cause thermal damage to this specific alloy grade.
I have an old mechanical hobbing machine. Can I use this?
Yes, absolutely. In fact, the N-Series is explicitly stated to be usable on slow traditional hobbing machines . Its superior toughness makes it more resistant to the vibration and rigidity issues often found in older equipment compared to harder, more brittle carbide grades.
What is the hardness limit for the workpiece?
I We recommend the N-Series for materials with a hardness of ≤ HRC 30° . For harder materials (HRC 45-62), you must use our G-Series , which is specifically designed for hard cutting. Using the N-Series on hard steel will result in rapid wear.
Can you manufacture custom profiles (Splines, Sprockets)?
Yes. While Standard sizes like φ32×φ13×L50 are standard, we support batch customization for various shapes and sizes. We can design profiles for splines, timing pulleys, and non-standard gears to DIN AA accuracy.
Why do you use PVD coating on an economical tool?
Because coating peeling is a major issue with cheap tools. Nobeve uses BALINIT® ALCRONA PRO even on the N-Series. Combined with our Cleaning-Sandblasting and Edge Passivation process, we ensure the coating adheres perfectly, protecting the substrate and extending tool life significantly.
Can you manufacture custom profiles (Protuberance, Tip Relief)?
Yes, 70% of our orders are customized. We perform Simulated Cutting Analysis before manufacturing. Based on your gear data and grinding stock (e.g., 0.15mm), we calculate the exact protuberance and chamfer angles to prevent grinding notches (undercutting) during finishing.

Testimonials
What Our Client’s Say
Carlos M.
Production Manager,Agricultural Machinery
“We produce thousands of gears for agricultural tractors every month. The N-Series fits our older machines perfectly and costs half of what we used to pay for European brands.”
Rajesh K.
Workshop Owner General Transmission
“Transitioning from HSS to the Nobeve N-Series was a game changer. We run them at 120m/min on our YK3150 machines with oil.”
Liam T.
Procurement Officer Industrial Components
“I was skeptical about 'ordinary alloy' at first, but for our HRC 25 spline shafts, these tools are unbeatable. The finish is smooth, and we get predictable wear patterns that allow us to regrind multiple times.”
