DNMG150604-PM YBM251 Stainless Steel Turning Inserts
Product Overview
The DNMG150604-PM YBM251 is a high-performance 55° rhombic negative insert engineered specifically for Stainless Steel (M-Class). The YBM251 Grade utilizes a specialized CVD coating that combines high wear resistance with the toughness needed for medium machining. Its -PM chipbreaker (Semi-Finishing to Medium) features a unique rake angle design that reduces cutting forces and heat buildup—the two primary enemies of stainless steel machining.
Key Performance Advantages
- ✔ YBM251 Grade Technology: Second-generation CVD coating optimized for thermal stability and anti-adhesion (Built-up Edge prevention).
- ✔ -PM Geometry: Designed for stable chip breaking across a wide range of feed rates, especially in gummy materials like Austenitic Stainless.
- ✔ 6.35mm Thickness (06): Enhanced insert thickness provides superior mechanical strength and better heat dissipation than the 04 series.
- ✔ Double-Sided Design: 4 usable cutting edges for maximum cost-per-edge efficiency.

— Stefan M., Germany 🇩🇪⭐⭐⭐⭐⭐
"Good impact resistance"
Stable performance even on interrupted cuts in stainless shafts.
— Sato K., Japan 🇯🇵⭐⭐⭐⭐
"Ottimo rapporto qualità"
Excellent finish quality on small diameter stainless parts.
— Fabio R., Italy 🇮🇹Frequently Asked Questions
Q: What is the benefit of the -PM chipbreaker for stainless?
A: Stainless steel is gummy and generates high heat. The -PM geometry has a sharper edge and optimized rake to "curl" and break the chip quickly, preventing work-hardening of the workpiece.
Q: Can I use this for finishing?
A: With a 0.4mm nose radius, it provides an excellent finish. However, for high-precision finishing, the -PF breaker may be preferred.
Q: Is this original ZCC.CT?
A: Yes, we sell only 100% genuine ZCC.CT products in original factory packaging.
Material Comparison Tip: When machining Standard Stainless Steel at medium speeds, YBM251 is the safest and most economical choice. If you are running high-speed production on rigid machines, consider YBM151 for maximum tool life.

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.
Our automatic quantity discount is 6% off for 2–9 items and 12% off for 10 or more items, based on the total product quantity in the cart. Other offers may not combine with this discount; check the applicable offer conditions.
