APKT11T308-PF YBC302 Milling Insert
Elite CVD Coated Grade for High-Precision Steel Finishing
Product Overview
"Which carbide insert is the most reliable for achieving a mirror-like surface finish in carbon steel and alloy steel components?"
The APKT11T308-PF YBC302 is ZCC.CT's premier solution for finishing operations in ISO P (Steel) materials. Combining a high-strength carbide substrate with the advanced YBC302 CVD coating (featuring thick Al2O3 and TiCN layers), this insert offers incredible wear resistance and thermal stability. The -PF chipbreaker is specifically designed for finishing, with a sharp geometry and positive rake angle that ensures smooth chip evacuation at lower depths of cut, preventing work hardening and surface defects.
Key Features
- ✔ Thick Al2O3 CVD Coating: Provides a superior thermal barrier for high-speed machining without edge deformation.
- ✔ PF Finishing Geometry: Sharp cutting edge designed for light depths of cut (Ap) and high surface brightness.
- ✔ 0.8mm Corner Radius: Enhanced edge strength compared to 0.4mm versions, ideal for high-feed finishing and corner durability.

"The PF chipbreaker is excellent. We reached an Ra of 0.8 in 1045 steel without effort. Highly recommended."
— Mark R., United States
"Sehr gute Oberflächengüte. Die Standzeit des YBC302 ist bei der Schlichtbearbeitung beeindruckend."
— Stefan B., Germany
"仕上げ加工に最適です。切り屑の処理も非常に安定しています。コストも満足。"
— Kenji T., Japan
Industrial FAQ
A: The PF geometry is designed for finishing. For heavy roughing, we recommend the -PM or -GM chipbreakers for better edge strength.
A: CVD coatings perform excellently in dry milling for steel. However, for finishing, air-blast is recommended to keep the surface clear of chips.
A: For the PF chipbreaker, the optimal Ap is between 0.1mm and 1.5mm to ensure best chip breaking performance.
💡 Material Tip: To achieve the best surface finish with YBC302, use the highest recommended cutting speed (Vc). High speeds reduce the built-up edge (BUE) and provide a superior gloss on steel parts.

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.
