ZCC.CT RDKW1605MO YBG212 Round Milling Insert
The Industrial Standard for Profiling Hardened Steel & Cast Iron
Product Overview
The ZCC.CT RDKW1605MO in the YBG212 grade is a powerhouse for modern CNC milling. Specifically designed for ISO P (Steel) and ISO K (Cast Iron), this 16mm round insert features the advanced YBG212 PVD coating. This coating is a multi-layer TiAlN solution that offers exceptional thermal stability and surface hardness. The MO chipbreaker geometry is engineered for medium-range milling, providing a reinforced edge that prevents micro-chipping in tougher, hardened materials. Its round geometry allows for maximum metal removal rates (MRR) through the chip-thinning effect.
Key Core Advantages
- ▶ Nano-PVD YBG212 Grade: Excellent resistance to thermal shock and mechanical impact, ideal for dry milling.
- ▶ High-Feed Efficiency: The round profile enables significantly higher feed rates compared to square inserts.
- ▶ Versatile Profiling: Perfect for 3D copy milling, plunging, and complex mold and die surfaces.

Real Machinist Reviews
"YBG212 is a beast on hardened D2 tool steel. The round inserts last 30% longer than my previous brand."
— James W., USA 🇺🇸"Sehr gute Qualität. Wir nutzen diese für die Bearbeitung von Gussformen. Standzeit ist top."
— Müller T., Germany 🇩🇪"Incredible surface finish on cast iron. The MO chipbreaker handles heat very well."
— Sato M., Japan 🇯🇵"Ottimo rapporto qualità-prezzo. Ideale per sgrossatura di precisione."
— Andrea L., Italy 🇮🇹Expert FAQ
Q: Can I use YBG212 for wet milling?
A: While it can be used with coolant, YBG212 is highly optimized for dry milling or air-blast cooling due to its superior thermal shock resistance.
Q: Is RDKW1605MO compatible with high-feed milling?
A: Yes. Round inserts naturally support high-feed rates because the chip thinning effect allows you to increase feed per tooth as depth of cut decreases.
Q: What is the maximum hardness YBG212 can handle?
A: It performs excellently on steels up to 50-55 HRC. For materials above 60 HRC, we recommend specialized CBN or ceramics.

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.
