ZCC.CT CNMG160608-PM YBM251: Heavy-Duty Stainless Steel Turning Insert
Product Overview
The ZCC.CT CNMG160608-PM YBM251 is a robust solution designed for Stainless Steel (ISO M) and heat-resistant alloys. Utilizing the YBM251 grade—a specialized substrate with a thick CVD coating—it excels in balancing wear resistance with impact toughness. The PM chipbreaker geometry is specifically refined for medium-range machining, providing stable chip evacuation and preventing built-up edge (BUE) on gummy stainless materials.
Key Features
- ✔ Enhanced CVD Coating: Thick TiCN + Al2O3 coating offers superior heat resistance during high-speed machining.
- ✔ PM Medium Geometry: Optimized edge strength for stable chip breaking across varying depths of cut.
- ✔ Heavy-Duty Substrate: The 16mm edge length (CNMG1606) provides the mass and stability required for larger workpieces.

FAQ - Frequently Asked Questions
Q1: Can I use this for Duplex Stainless Steel?
Yes, YBM251 is excellent for Duplex. We recommend staying on the lower end of the Vc range (90-120 m/min) for maximum tool life.
Q2: What is the benefit of the 0.8mm radius (08)?
The 0.8mm radius provides a stronger edge than 0.4mm, allowing for higher feed rates and better surface finishes in medium turning.
Technical FAQ & Buying Guide
Absolutely. Our CNC carbide inserts (including CNMG, WNMG, DNMG, and APMT series) are manufactured strictly adhering to international ISO/ANSI specifications. A CNMG 120408 from OYYU BEYOND will flawlessly fit any standard turning tool holder or indexable tool from major global brands like Sandvik Coromant, Kennametal, Iscar, Walter, or SECO, providing a highly cost-effective premium alternative without sacrificing tolerance or tool life.
We offer optimized CVD and PVD multi-layer coatings for different ISO material groups:
- For Carbon/Alloy Steel (ISO P): Choose our thick multi-layer CVD coated grades (e.g., Al2O3 + TiN). They provide exceptional crater wear resistance and thermal barriers during high-speed dry or wet roughing.
- For Stainless Steel (ISO M): Choose our nano-structured PVD coated grades with sharp, positive chipbreakers (like -TM or -MA). This combination prevents work hardening and effectively controls sticky chips.
The optimal cutting parameters vary depending on the workpiece hardness and operation type:
- For General Steel Turnings: Recommended cutting speed ($V_c$) ranges from 150 to 280 m/min, with a feed rate ($f$) of 0.15 to 0.45 mm/rev.
- For Stainless Steel Finishing: Recommended cutting speed ($V_c$) is 120 to 200 m/min, with a feed rate ($f$) of 0.10 to 0.25 mm/rev.Always adjust parameters based on early wear patterns: increase $V_c$ if built-up edge occurs, or reduce $V_c$ if severe flank wear is observed.
