APKT11T308-PM YB9320 ZCC.CT Milling Insert
0.8mm Standard Radius | Advanced Nano-PVD for Stainless Steel
Product Overview
"Need a reliable insert that conquers the stickiness and heat of stainless steel?"
The APKT11T308-PM YB9320 represents the premium tier of ZCC.CT's milling lineup. While the 0.8mm radius provides the versatility needed for 90° shoulder milling across diverse components, the YB9320 Grade is the star performer. It is engineered with a high-toughness substrate and a nano-structured PVD coating that offers exceptional resistance to "built-up edge" and thermal cracking. Whether you are machining 304, 316, or tricky alloy steels, this insert ensures stable tool life and high-efficiency metal removal.

Core Advantages
- Premium YB9320 Grade: Exceptional heat resistance and toughness for unstable stainless steel machining.
- Anti-Adhesion Coating: Specially treated PVD surface prevents metal chips from welding to the insert edge.
- Stable Edge Geometry: PM chipbreaker provides excellent chip control while maintaining a sharp cutting action.
- High Reliability: Optimized for semi-finishing to roughing, even in mildly interrupted cuts.
Application Scenarios
- Milling of austenitic stainless steels (304, 316, 316L).
- Processing of heat-resistant alloys and duplex stainless steel.
- Efficient shoulder milling in low-carbon steel components.
- General milling where tool life consistency is a priority.
Technical Data & Parameters
| Metric Model | Inch Equivalent | Cutting Speed (Vc) | Feed per Tooth (fz) |
|---|---|---|---|
| APKT11T308-PM | APKT 0.433" x 0.156" R0.031" | 120 - 280 m/min | 0.10 - 0.25 mm/z |
*Optimal speed varies by material hardness. Use high-pressure coolant for best results in stainless steel.

Technical FAQ
Yes. 11T3 (3.97mm) is the ISO standard designation. 1103 is often used interchangeably to indicate the same thickness. Both fit the same 11-size holders.
YB9320 is a higher-tier grade specifically optimized for the unique thermal properties of stainless steel. It offers better resistance to the chemical and heat-related wear that usually causes early failure in universal grades.
Stainless Steel Pro-Tip:
When machining stainless steel with YB9320, ensure you maintain a consistent minimum feed rate. Stainless steel tends to work-harden; if the feed is too light, the insert will "rub" against the work-hardened layer, causing rapid edge wear.

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.
