ZCC.CT TCMT110208-52 YBM251 Precision Insert
Mastering Stainless Steel with Advanced CVD Coating Technology
Product Overview
"Which carbide insert is best for finishing stainless steel while preventing notch wear and built-up edge?"
The ZCC.CT TCMT110208-52 YBM251 is a high-performance triangular turning insert specifically engineered for ISO M (Stainless Steel) applications. By utilizing the YBM251 grade—a specialized CVD coating with a sub-micron grain substrate—this insert excels in heat dissipation and edge toughness. The -52 chipbreaker is designed for high-precision finishing and semi-finishing, ensuring excellent chip breaking even in gummy materials like 304 or 316 stainless steel.
