ZCC.CT APKT160408-PF YBC301 Inserts
Advanced CVD Coated Carbide for High-Speed Steel Finishing Operations
Product Overview
"Which milling insert is most effective for achieving superior surface finishes in steel while maintaining high cutting speeds?"
The ZCC.CT APKT160408-PF YBC301 is a high-performance milling solution specifically engineered for steel (P-class) machining. Featuring the YBC301 CVD Al2O3 + TiCN coating, this insert is built to withstand high temperatures generated during high-speed cutting. The PF chipbreaker is precision-honed for finishing to semi-finishing, providing exceptional chip control and reducing cutting resistance. Its 0.8mm radius is the industry standard for 90° square shoulder milling where precision and edge integrity are paramount.
Key Features
- ✔ Thick CVD Coating: Al2O3 + TiCN coating provides a massive heat barrier for stable high-speed machining.
- ✔ PF Finishing Chipbreaker: Sharp cutting edge and positive rake angle reduce power consumption and BUE (Built-up Edge).
- ✔ Substrate Toughness: A gradient carbide substrate ensures the edge remains intact during moderate interrupted cuts.

ZCC.CT Grade Material Comparison
YBC301 vs. YBG202: While YBG202 is a PVD grade versatile for multiple materials, YBC301 is a specialized CVD steel grade. The thick Al2O3 layer in YBC301 provides significantly higher crater wear resistance at high temperatures. If you are milling carbon or alloy steel at high speeds, YBC301 will offer a 40% longer tool life and better thermal stability than PVD-coated alternatives.
Customer Success Stories
"Perfect for high-speed finishing on 1045 steel. The PF chipbreaker keeps the surface clean and shiny."
— Robert B., USA"Die Qualität von ZCC ist top. YBC301 hält die Hitze sehr gut aus. Sehr schnelle Lieferung."
— Klaus L., Germany"Ottimi inserti per finitura. Il rapporto qualità-prezzo è imbattibile rispetto ai marchi europei."
— Paolo M., Italy"Reliable performance in our mass production line. Corner radius is very precise."
— Kenji S., JapanFrequently Asked Questions
Is YBC301 suitable for stainless steel?
YBC301 is primarily optimized for steel (P). For stainless steel (M), we recommend ZCC.CT YBM grades or YBG202 for better results.
What depth of cut (Ap) is recommended for PF chipbreakers?
The PF (Finishing) chipbreaker is best used with an Ap between 0.5mm and 2.5mm for optimal chip breaking.
Material Pro Tip: High-Velocity Cutting
When using APKT160408-PF YBC301, do not be afraid to push the cutting speed (Vc). CVD coatings like the one on YBC301 require heat to activate the Al2O3 thermal barrier effectively. Cutting too slowly can actually reduce tool life by preventing the coating from reaching its optimal performance state.

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.
