ZCC.CT RCMT1204MO YBC151 Finishing Insert
High-Speed Precision and Superior Surface Finish for Steel
Product Overview
The ZCC.CT RCMT1204MO in YBC151 grade is a specialized 12mm round insert designed for high-efficiency finishing and semi-finishing. Unlike tougher roughing grades, the YBC151 features a thick CVD Al2O3 coating specifically balanced for ISO P10-P20 applications. This means it can withstand the extreme heat of high cutting speeds while maintaining a sharp edge to prevent work hardening. The round geometry offers maximum edge strength and versatility for profiling, making it the go-to choice for complex molds and high-precision shaft turning.
Key Core Advantages
- ★ High-Speed Stability: Engineered for Vc speeds up to 350 m/min in stable steel conditions.
- ★ Superior Wear Resistance: The multi-layer CVD coating drastically reduces crater wear during continuous finishing.
- ★ Versatile Profiling: Round shape allows for multi-directional cutting and excellent chip control in profiling.

Voice of the Professional
"YBC151 is our standard for steel shaft finishing. We doubled our cutting speed compared to the generic grade we used before."
— David S., USA 🇺🇸"Ottima qualità superficiale. Per la finitura su acciaio legato è imbattibile."
— Paolo R., Italy 🇮🇹"Sehr gute Standzeit bei hohen Schnittgeschwindigkeiten. Empfehlenswert!"
— Markus K., Germany 🇩🇪"The MO chipbreaker works great for chip control in finishing. Very clean finish."
— Kenji T., Japan 🇯🇵FAQ
Q: Can I use YBC151 for interrupted cuts?
A: We do not recommend it. YBC151 is a high-hardness finishing grade. For interrupted cuts, we suggest YBC252 or YBC352 for higher toughness.
Q: Is this insert compatible with standard holders?
A: Yes, it fits any tool holder designed for ISO RCMT1204 specifications.
Q: What is the "MO" chipbreaker best for?
A: The MO geometry is optimized for medium-to-finishing cuts, providing excellent surface quality and stable chip evacuation at lower feed rates.

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.
