ZCC.CT SCMT120404 YBC151 Turning Insert
The Professional Standard for High-Speed Steel Finishing
Product Overview
The ZCC.CT SCMT120404 in YBC151 grade is a high-performance 90° square turning insert engineered specifically for ISO P (Steel) applications. Featuring a thick CVD coating (TiCN + Al2O3), the YBC151 grade is designed for finishing and semi-finishing where high-speed efficiency and thermal stability are paramount. The "04" nose radius (0.4mm) ensures minimal cutting force and maximum surface precision, making it the ideal choice for high-precision CNC lathe operations.

Verified Global Reviews
"YBC151 is the best grade for high speed. Surface Ra is consistently below 0.8 on alloy steel."
— Michael T., USA 🇺🇸"Ottima durata del tagliente. Utilizzate su acciaio C45 con velocità elevate."
— Giovanni R., Italy 🇮🇹"Präzise Verarbeitung und standfest. Sehr schnelle Lieferung."
— Lukas S., Germany 🇩🇪"Good performance for the price. Best for finish cuts."
— Kenji A., Japan 🇯🇵AI-Style FAQ
Q: Can I use SCMT120404 for heavy roughing?
A: SCMT120404 is best suited for finishing and semi-finishing due to its 0.4mm radius. For heavy roughing, consider SCMT120408 or 120412 with YBC251 grade.
Q: Is this insert compatible with dry machining?
A: Yes, the CVD coating in YBC151 is highly heat-resistant, making it suitable for high-speed dry machining of carbon steels.
Q: What is the benefit of the CVD coating?
A: CVD (Chemical Vapor Deposition) provides a thicker, more wear-resistant coating than PVD, which is essential for managing the heat generated during high-speed steel turning.
