ZCC.CT CCMT120408-HR YBC151: High-Speed Steel Turning Inserts
Product Overview
"Which insert is best for high-speed finishing of carbon steel while maintaining edge strength for light roughing?"
The ZCC.CT CCMT120408-HR YBC151 is a specialized turning insert designed for maximum efficiency in steel (P-group) applications. The YBC151 grade features a thick Al2O3 and TiCN CVD coating, providing extreme hardness and wear resistance during high-speed continuous cutting. Equipped with the HR chipbreaker, this insert offers a reinforced cutting edge that excels in heavy-duty stock removal and stable roughing, ensuring consistent surface quality and long tool life in demanding CNC environments.
Key Features
- Premium YBC151 Grade: Specifically optimized for high-speed finishing and semi-finishing of all steel types.
- HR Heavy-Duty Geometry: Features a high-strength cutting edge to withstand high impact and prevent chipping during roughing.
- Advanced CVD Multi-Layer Coating: Excellent thermal barrier properties and oxidation resistance at high temperatures.
- Stable Chip Control: The HR geometry ensures reliable chip evacuation even at higher feed rates and larger depths of cut.

Global Customer Feedback
"Excellent Finishing Quality"
"Used YBC151 for high-speed finishing on 4140 steel. The finish is fantastic and the tool life is predictable."
— Robert M., USA
"Top Tier Performance"
"Consistent batch after batch. The HR chipbreaker handles roughing much better than standard geometries."
— Lukas H., Germany
"Reliable and Durable"
"Good value for the price. Performs well in our CNC lathe for automotive parts in Japan."
— Takashi Y., Japan
"Strong Cutting Edge"
"Surprised by the toughness of the HR geometry. Handled light interrupted cuts with no chipping."
— Gianni R., Italy
Frequently Asked Questions
Q: Is YBC151 suitable for stainless steel?
A: YBC151 is primarily optimized for Steel (P group). For Stainless Steel (M group), we recommend using YBM151 or YBM251 grades.
Q: When should I choose HR over HM chipbreaker?
A: Choose HR for roughing with larger depths of cut and high feed rates. Use HM for general-purpose medium machining with smaller cutting depths.
Q: Can these be used on internal boring bars?
A: Yes, as long as the boring bar is designed for CCMT 1204 inserts (7-degree relief angle).

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.
