Recommended Cutting Parameters
Achieve peak efficiency in your CNC milling operations with these YBG202 settings:
- Cutting Speed (Vc): 140 - 260 m/min (Steel) | 120 - 220 m/min (Stainless)
- Feed per Tooth (fz): 0.10 - 0.35 mm/z
- Max Depth of Cut (ap): Up to 6.0 mm (depending on setup)
*For heavy profile milling, ensure high-pressure coolant or air blast for chip evacuation.
Material Grade: YBG202 nc-TiAlN
The YBG202 grade is a "universal" PVD grade. Its nano-structured coating provides a smooth surface that prevents built-up edge (BUE), which is critical when milling sticky materials like 304/316 stainless steel. It balances hardness for wear resistance and toughness for interrupted cuts.
Round Geometry Advantages
The RDKW round insert design offers the strongest cutting edge of any insert shape. It allows for high feed rates and provides an excellent surface finish for 3D profiling and large-scale face milling.

"Genuine ZCC quality. YBG202 is my go-to for general stainless work."
⭐⭐⭐⭐ "Great finish" - Sato R., Japan
"Surface finish on our 304 parts is very reflective. Good chip breaking at high feeds."
⭐⭐⭐⭐⭐ "Very durable" - Ivan P., Poland
"Stable performance even in old machines. Fast shipping from the supplier."
⭐⭐⭐⭐⭐ "Cost-effective" - Liam W., Australia
"Performance is comparable to top European brands but at half the price."
FAQ - RDKW 1204 MO
Q: Can I use this for ramping?
A: Yes, round inserts like the RDKW 1204 are ideal for circular interpolation and ramping into the workpiece.
Q: Is this suitable for dry milling?
A: YBG202 is optimized for wet milling, but for steel milling at higher speeds, air-cooled dry milling can also prevent thermal cracking.
ZCC.CT Grade Comparison Tip
While YBG202 is the best all-around grade for P and M materials, if you are machining hardened steel (>45 HRC), we recommend checking our YBS series. For aluminum, always use the YD series (uncoated) for the sharpest edge possible.
