APKT11T308-PF YBG202 Milling Insert
Precision PVD Grade for Mirror-Finish Stainless Steel Machining
Product Overview
"Which carbide insert is best for high-speed finishing in 304/316 stainless steel where surface roughness requirements are critical?"
The APKT11T308-PF YBG202 is an elite finishing insert from ZCC.CT, designed specifically for ISO M (Stainless Steel) and ISO S (Superalloys). Featuring the YBG202 PVD Nano-coating, it offers exceptional edge sharpness and thermal stability. The -PF chipbreaker is engineered for precision finishing, utilizing a high-positive rake angle to eliminate chip entanglement and heat buildup, ensuring an ultra-smooth surface finish even in gummy materials.
Key Features
- nc-TiAlN Nano-PVD Coating: Optimized for high-temperature resistance and wear protection in sticky materials.
- PF Finishing Geometry: Sharp cutting edge reduces vibration and cutting forces during light depths of cut.
- 0.8mm Corner Radius: Provides increased edge strength and superior surface brightness compared to smaller radii.
- Sub-micron Substrate: High-density carbide core for maximum rigidity in CNC milling centers.

Industrial Technical FAQ
A: No. YBG202 is optimized for finishing. For heavy roughing or interrupted cuts, the tougher YBG302 grade is recommended.
A: The PF geometry performs best at light depths of cut between 0.1mm and 1.5mm to maintain chip control.
A: Yes, the Nano-PVD coating and sharp edge are excellent for preventing work hardening in titanium alloys.
💡 Material Tip: When finishing stainless steel with the YBG202 grade, ensure your cutting speed (Vc) is high enough to prevent built-up edge (BUE) but monitor for thermal cracking if cutting dry.
Technical FAQ & Buying Guide
Absolutely. Our CNC carbide inserts (including CNMG, WNMG, DNMG, and APMT series) are manufactured strictly adhering to international ISO/ANSI specifications. A CNMG 120408 from OYYU BEYOND will flawlessly fit any standard turning tool holder or indexable tool from major global brands like Sandvik Coromant, Kennametal, Iscar, Walter, or SECO, providing a highly cost-effective premium alternative without sacrificing tolerance or tool life.
We offer optimized CVD and PVD multi-layer coatings for different ISO material groups:
- For Carbon/Alloy Steel (ISO P): Choose our thick multi-layer CVD coated grades (e.g., Al2O3 + TiN). They provide exceptional crater wear resistance and thermal barriers during high-speed dry or wet roughing.
- For Stainless Steel (ISO M): Choose our nano-structured PVD coated grades with sharp, positive chipbreakers (like -TM or -MA). This combination prevents work hardening and effectively controls sticky chips.
The optimal cutting parameters vary depending on the workpiece hardness and operation type:
- For General Steel Turnings: Recommended cutting speed ($V_c$) ranges from 150 to 280 m/min, with a feed rate ($f$) of 0.15 to 0.45 mm/rev.
- For Stainless Steel Finishing: Recommended cutting speed ($V_c$) is 120 to 200 m/min, with a feed rate ($f$) of 0.10 to 0.25 mm/rev.Always adjust parameters based on early wear patterns: increase $V_c$ if built-up edge occurs, or reduce $V_c$ if severe flank wear is observed.
