ZCC-CT DCMT11T304-HM YBM251 – Turning Carbide Insert

DCMT11T304-HM YBM251 Turning Inserts Product Overview “Which carbide insert provides the highest reliability and chip control when semi-finishing duplex or austenitic stainless steel?” The DCMT11T304-HM YBM251 is a high-performance 55° rhombic positive insert specifically engineered for Stainless Steel (M-Class). By utilizing the YBM251 Grade—which features a specialized CVD coating with high thermal stability and impact resistance—this insert excels in medium-duty turning. The -HM (Medium-Duty) chipbreaker is designed with a reinforced edge and optimized rake angle to manage the high cutting forces and work-hardening characteristic of stainless materials. Key Advantages ✔ YBM251 Grade Technology: A tough substrate combined with thick CVD coating for M15–M35 applications, offering superior notch wear resistance. ✔ -HM Chipbreaker: Optimized for medium cutting depths, ensuring stable chip breaking and reducing the risk of built-up edge (BUE). ✔ High Thermal Stability: Maintains cutting edge integrity even under high-temperature continuous machining. ✔ Versatile Application: Ideal for both internal boring and external turning of stainless steel components.

YBM151: Higher speed, stable finishing of stainless. YBG205: Optimized PVD grade for high-precision finishing. Why Choose ZCC.CT Tools? As a global leader in cemented carbide technology, ZCC.CT provides high-precision CNC solutions that reduce costs and increase productivity. The YBM series is internationally recognized for its stability in difficult-to-machine materials, ensuring your workshop achieves mirror-like finishes and consistent tool life. Verified Customer Reviews ⭐⭐⭐⭐⭐ “Exceptional tool life in 316” We use YBM251 in our Ohio shop for pump components. The chip control is fantastic at medium speeds. — David S., USA ⭐⭐⭐⭐⭐ “Top Performance” Consistent quality across batches. The -HM breaker is very versatile for various stainless grades. — Klaus H., Germany ⭐⭐⭐⭐ “Affidabile e Preciso” Great for semi-finishing. Excellent surface finish on austenitic steel shafts. — Roberto M., Italy ⭐⭐⭐⭐⭐ “コストパフォーマンス最高” Stable performance in heavy production runs. Highly recommended for CNC lathes. — Hiroshi T., Japan Frequently Asked Questions Q: Is YBM251 suitable for dry machining?A: While YBM251 has high thermal stability, using high-pressure coolant is highly recommended for stainless steel to prevent work hardening and improve tool life. Q: What is the difference between -HM and -HF breakers?A: -HM is for medium-duty semi-finishing with larger depths of cut, while -HF is designed for high-precision light finishing with smaller feed rates. Q: Can I use this for duplex stainless?A: Yes, the YBM251 grade is tough enough to handle the higher cutting forces and abrasion of 2205 duplex steel. Material Comparison Tip: For high-speed machining of Austenitic Stainless, YBM251 is the primary choice. However, if you are machining small components with thin walls, the YBG205 (PVD) grade might offer lower cutting forces to prevent part deflection.

Bulk Pricing Available – Discount tiers for production-volume orders; contact sales.
QC Inspected – Each batch sampled for edge profile, dimensional accuracy, and coating adhesion.
Predictable Wear – Even flank wear pattern simplifies tool-life prediction and scheduling.
tin Coating – Superior wear resistance and extended tool life under continuous load.
Optimized Chip Breaker – Engineered chip geometry reduces re-cutting and machine downtime.

Recommended Applications

Finish Machining of steel, stainless steel in production CNC lines
Designed for shop conditions typical of ZCC-CT tooling users worldwide
Holds dimensional tolerance over multiple indexings (insert)
Pairs well with through-coolant setups for chip evacuation

Buying Considerations

Single-pack option — useful for prototype runs or qualification before bulk commitment. Mid-tier pricing reflects ZCC-CT’s production-grade tolerances rather than economy substrate.

Tip: Match this insert to a holder whose seat matches the ISO designation. If you’re unsure, send us the holder model and we’ll confirm compatibility before shipping.
