APKT11T308-PM YBC301 ZCC.CT Milling Insert
High-Speed CVD Precision Solution for ISO P Steel Machining
Product Overview
"Seeking to reduce cycle times while maintaining a superior surface finish in steel components?"
The APKT11T308-PM YBC301 is engineered for performance at higher cutting speeds. While the PM (General Purpose) geometry provides a sharp yet controlled cutting action, the YBC301 Grade sets it apart. This specialized CVD coating features a fine-grained substrate and high-hardness layer, making it significantly more resistant to plastic deformation and crater wear than tougher grades like YBC302. It is the definitive choice for Semi-Finishing to Finishing in stable machining environments.

Product Core Advantages
- High-Speed YBC301 Grade: Excellent red-hardness allows for significantly higher spindle speeds in carbon and alloy steels.
- Superior Surface Finish: PM geometry reduces cutting heat at the tip, ensuring clean finishes.
- Increased Wear Resistance: Thick CVD coating specifically combats crater wear on the rake face.
- Precise 0.8mm Radius: Provides the structural strength needed for consistent performance during long runs.
Application Scenarios
- High-efficiency shoulder milling of pre-hardened steels and alloy steels.
- Finishing operations where dimensional accuracy is critical.
- Best used on CNC milling machines with high rigidity and stability.
- Perfect for industrial batch production aiming for high metal removal rates.

Global Verified Feedback
"We switched to YBC301 for our alloy steel finishing. Tool life increased by 20% compared to other standard CVD grades."
J. Henderson - USA"Ottimo per velocità elevate su C45. Superficie lucida e costante."
Paolo V. - Italy"Consistent quality from ZCC. The YBC301 is very predictable at high RPMs. PM geometry is perfect."
Mark D. - UKTechnical FAQ
No. YBC301 is better for high-speed finishing in stable conditions. If you have heavy vibrations or interrupted cuts, YBC302 is the safer choice due to its higher toughness.
While it can work, ZCC.CT's YBD (Black Diamond) series is specifically optimized for Cast Iron. For best results in iron, use YBD152 or YBD252.
CNC Performance Tip:
When utilizing the high-speed capabilities of YBC301, ensure your machine spindle is balanced and your holder runout is minimal. Even minor runout can lead to chipping at higher Vc. For finish milling, try slightly increasing the cutting speed while keeping a steady feed to achieve a mirror-like surface on alloy steels.

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.
