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.
