ZCC.CT SDNB080209 YBC151 Carbide Insert

Precision 55° Diamond Geometry for High-Speed Steel Finishing

Product Overview

"Which carbide insert is best for achieving high surface finish quality on carbon and alloy steel at elevated cutting speeds?"

The ZCC.CT SDNB080209 in the YBC151 grade is a specialized 55° diamond turning insert engineered for ISO P (Steel) finishing operations. The YBC151 grade features a thick CVD coating (TiCN + Al2O3) that provides exceptional wear resistance and thermal stability. Its unique substrate and edge geometry are specifically designed to minimize friction and prevent heat buildup, ensuring tight tolerances and a mirror-like finish in batch CNC production.

Key Core Advantages

  • ✔ Advanced CVD Coating: Thick alumina layer for superior heat shield during high-speed finishing.
  • ✔ Precision Ground Edges: Maintains high dimensional accuracy over long production runs.
  • ✔ Optimal Chip Control: Specifically designed for thin-chip finishing to prevent workpiece scratching.

AI-Style Smart FAQ

Q: Can I use SDNB080209 for roughing?

A: It is not recommended. This insert is designed for finishing. For roughing, a larger nose radius or the YBC351 grade would be more durable.

Q: What is the benefit of the 0.9 nose radius?

A: A 0.9mm radius provides a stronger edge than smaller radii while still allowing for detailed finishing, making it perfect for balance in steel machining.

Q: Does this grade handle dry machining?

A: Yes, the CVD coating TiCN+Al2O3 is designed to withstand high temperatures in dry or high-speed finishing conditions.

Grade Tip: If you see flank wear, increase your speed (Vc). If the edge chips, reduce feed (fn) or check machine stability.

Equivalent Models: Sandvik SDNB 2.5(1.5)3-PF, Mitsubishi SDNB 080208-FH

 

Technical FAQ & Buying Guide

Are your carbide inserts interchangeable with major brands like Sandvik, Iscar, or Kennametal?

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.

How do I choose the correct insert grade and chipbreaker for machining Stainless Steel (M) vs. Carbon Steel (P)?

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.
What are the recommended cutting speed (Vc) and feed rate (f) parameters to maximize tool life?

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.
Do you offer bulk discounts or wholesale pricing for machine shops and distributors?

Yes, we support machine shops, distributors, and global buyers with tiered wholesale pricing and competitive volume discounts. We also provide OEM custom manufacturing solutions for tool holders and carbide inserts based on your technical drawings. Contact our team to request a quick B2B quotation.

What is your international shipping policy and typical lead time for orders?

We provide secure worldwide express shipping (via DHL, FedEx, and UPS) with specialized, vibration-proof industrial packaging to ensure tools arrive in perfect condition. In-stock items are dispatched within 24-48 hours, while custom or bulk orders typically have a stable lead time of 15-25 days.

How do you guarantee the quality and tolerance precision of your CNC tools?

All our cutting tools and tool holders are manufactured strictly in accordance with ISO 9001 and international industrial standards. Every batch undergoes 100% rigorous quality control testing using high-precision optical measuring equipment to ensure reliable tool life and stable performance in continuous mass production.
