Advanced Grade: UE6020 (The Steel Specialist)

The UE6020 grade is a versatile CVD coated carbide specifically developed for P-class steel materials. It excels in a wide range of cutting conditions, from continuous to interrupted cutting. The multi-layer coating provides excellent resistance to cratering and flank wear, making it an ideal choice for carbon steel, alloy steel, and mild steel machining where reliability is paramount.

GH Chipbreaker Geometry

The GH (General Heavy) chipbreaker is designed with a high-strength cutting edge. In CNC turning, roughing passes require an insert that can handle heavy loads and large depths of cut without chipping. The GH geometry provides stable chip control and reduces the risk of sudden tool failure, ensuring smooth operations on your CNC lathe.

Recommended Cutting Parameters

Optimized for Steel (P-Class):

  • Cutting Speed (Vc): 120 - 280 m/min (390 - 920 SFM)
  • Feed Rate (f): 0.20 - 0.50 mm/rev (0.008 - 0.020 ipr)
  • Depth of Cut (ap): 1.0 - 4.5 mm

*Pro Tip: For improved tool life in continuous cutting, aim for the mid-range of the recommended cutting speed.*

Technical Q&A

Q: Can I use UE6020 for Stainless Steel?

A: UE6020 is specialized for Steel (P-Class). For stainless steel, we recommend the US735 or MC7025 grades for better performance.

Q: What is the maximum feed rate for this insert?

A: With the GH breaker, you can comfortably reach up to 0.50 mm/rev depending on the material hardness and setup stability.

Q: Is this insert compatible with standard holders?

A: Yes, it fits any standard MWLNR / DWLNR holder. The WNMG shape offers 6 usable edges for superior cost-effectiveness.

Expert Machining Tip: UE6020 vs MC6025

For General Steel Machining, UE6020 is an excellent reliable choice. If you are doing High-Speed Steel Turning with stable setups, consider the MC6025 grade for even higher wear resistance.

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?
