SEEN1203AFTN YNG151: The Ultimate Cermet Solution for Mirror Finishing
Product Overview
The SEEN1203AFTN YNG151 is a high-performance cermet milling insert engineered by ZCC.CT. Unlike standard carbide, the YNG151 Cermet grade combines the toughness of ceramic with the metallic binder of titanium, offering exceptional chemical stability and low affinity for workpiece materials. This ensures a mirror-like surface finish and prevents built-up edge (BUE) during light roughing to high-speed finishing of steel and cast iron.
Why Choose YNG151 Cermet?
- ✔ Superior Surface Quality: Low friction coefficient ensures extremely low surface roughness (Ra) on the workpiece.
- ✔ Extreme Oxidation Resistance: Maintains hardness at higher temperatures where traditional carbide fails.
- ✔ High Dimensional Accuracy: Excellent wear resistance ensures tool consistency during long production runs.

— Klaus L., Germany 🇩🇪⭐⭐⭐⭐⭐
"Ottimo rapporto qualità-prezzo. Finitura a specchio su ghisa."
— Fabrizio B., Italy 🇮🇹⭐⭐⭐⭐⭐
"Excellent anti-seizing properties. No BUE even at 300m/min."
— Sato T., Japan 🇯🇵Frequently Asked Questions
Q: Why use Cermet (YNG151) instead of Tungsten Carbide?
A: Cermet has lower affinity for iron-based metals, which means less sticking (BUE) and much better surface gloss compared to carbide.
Q: Can SEEN1203AFTN handle heavy roughing?
A: No, Cermet is more brittle than carbide. It is strictly designed for high-speed finishing and semi-finishing with small depths of cut.
Q: Is dry machining recommended?
A: Yes, Cermet performs exceptionally well in dry machining because it has high thermal stability and oxidation resistance.
Industrial Tech Tip: For the best results with YNG151, maintain a stable cutting speed. If you see chipping, reduce the feed rate per tooth (fz) but keep the speed (Vc) high to leverage the thermal properties of cermet.

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.
