ZCC.CT CCMT09T304-HM YBM151: High-Speed Stainless Steel Precision
Product Overview
The ZCC.CT CCMT09T304-HM YBM151 is a premium industrial grade insert engineered specifically for the M-group (Stainless Steel). The YBM151 grade utilizes a thin, high-density CVD coating coupled with a fine-grained substrate, providing extreme wear resistance at elevated cutting speeds. Combined with the HM (Medium-Finishing) chipbreaker, it effectively manages long, stringy stainless steel chips, preventing workpiece scratching and ensuring high dimensional accuracy.
Key Features
- YBM151 High-Speed Grade: Optimized for finishing to semi-finishing at high velocities with minimal thermal deformation.
- HM Precision Geometry: A stable cutting edge that balances sharpness and strength to minimize built-up edge (BUE).
- Superior Surface Finish: The 0.4mm (0.016") nose radius is designed for low cutting forces and ultra-smooth finishes.
- Advanced CVD Coating: Provides a hard barrier against chemical wear and notch wear, common in austenitic stainless steels.

Why Choose ZCC.CT?
"Flawless Surface Finish"
"Used for 316L valve stems in the UK. The YBM151 grade allowed us to increase Vc by 30% while maintaining a mirror finish."
— David R., UK
"Excellent Chip Control"
"The HM chipbreaker works exactly as described. No bird-nesting even on gummy stainless parts in our Germany shop."
— Lukas M., Germany
"Reliable Performance"
"Top quality inserts from Japan. Consistency between batches is impressive for the price point."
— Kenji T., Japan
Frequently Asked Questions
Q: Can I use this for titanium machining?
A: While optimized for stainless steel, YBM151 can handle some titanium alloys at lower speeds. For dedicated titanium work, we recommend the YBS series.
Q: What is the main benefit of the HM chipbreaker?
A: It is designed for medium-finishing, providing a stable cutting edge that excels in chip evacuation for stainless steel to prevent tool failure.
Q: Is it suitable for dry machining?
A: For stainless steel, we always recommend high-pressure coolant to prevent work hardening and extend the life of the YBM151 coating.

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.
