ZCC.CT CCMT09T304-HM YBC151: High-Speed Precision Steel Finishing
Product Overview
The ZCC.CT CCMT09T304-HM YBC151 is the professional's choice for precision steel turning (P-group). The YBC151 grade features a high-wear-resistance substrate combined with a thick Al2O3 and TiCN CVD coating, engineered for high cutting speeds where thermal resistance is paramount. With a precision 0.4mm (0.016") nose radius and the HM chipbreaker, this insert provides superior surface integrity and stable chip breaking even at lower feed rates.
Key Features
- YBC151 Wear-Resistant Grade: Specifically optimized for high-speed finishing of carbon and alloy steels (P05-P15 range).
- HM Chipbreaker: Designed for stable medium-to-finishing operations, providing excellent chip control across varying depths of cut.
- CVD Coating Technology: Advanced multi-layer coating reduces friction and crater wear during prolonged machining.
- Precision 0.4mm Radius: Minimizes cutting force and vibration, making it perfect for slender shafts and thin-walled parts.

— Hiroshi K., Japan
Frequently Asked Questions
Q: Can I use YBC151 for interrupted cutting?
A: YBC151 is optimized for high-speed continuous cutting. For heavy interrupted cuts, we recommend the tougher YBC251 grade.
Q: What is the benefit of the 04 (0.4mm) radius over the 08 (0.8mm)?
A: The 0.4mm radius generates lower cutting forces and heat, making it superior for fine surface finishes and machining thin-walled parts.
Q: Is this insert compatible with stainless steel?
A: While it can cut ferritic stainless steel, it is primarily designed for steel. For austenitic stainless steel (304/316), the YBM series is highly recommended.

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.
