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
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.
