DNMG150608-PM YBD252: High-Stability Cast Iron Turning
Product Overview
The DNMG150608-PM YBD252 is an industrial-grade turning solution specifically designed for the Cast Iron (K-Class) family. The YBD252 grade features a specialized thick CVD coating that offers superior resistance to abrasive wear and thermal cracking. Paired with the -PM (Semi-Finishing to Medium) chipbreaker, this insert delivers exceptional stability and chip control in materials like Ductile Iron (FCD) and Grey Iron (FC).
Key Performance Advantages
- ✔ YBD252 Technology: Advanced CVD coating with Al2O3 and TiCN layers provides high hardness and heat resistance at the cutting zone.
- ✔ -PM Geometry: A versatile chipbreaker that balances edge strength with sharp cutting action, ideal for cast iron's brittle chip nature.
- ✔ Abrasive Resistance: Specifically formulated substrate to prevent flank wear caused by the high carbon/silicon content in cast iron.

Stable at 300 m/min. The finish is excellent for a PM breaker.
— Sato M., Japan 🇯🇵⭐⭐⭐⭐
"Qualità costante"
Great balance between cost and tool life. Minimal edge chipping.
— Paolo C., Italy 🇮🇹Frequently Asked Questions
Q: Why use YBD252 instead of a general steel grade?
A: Cast iron contains high amounts of silicon and carbon, which are highly abrasive. YBD252 has a coating thickness and substrate toughness designed specifically to combat this abrasive wear, which would quickly destroy a steel grade insert.
Q: What is the optimal coolant setup for this insert?
A: While YBD252 handles dry machining well on grey iron, using high-pressure coolant on ductile iron can significantly improve tool life and surface finish.
Q: Is this original ZCC.CT?
A: Yes, we are an authorized distributor. All inserts come in original factory-sealed 10-piece packaging with QR code verification.
Material Selection Tip: For Grey Cast Iron (GG) with stable cuts, you can increase speed up to 400 m/min. For Ductile Iron (GGG), maintain a more conservative feed rate to protect the nose radius.

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.
