Grade: UE6020 (The Industry Workhorse)

The UE6020 grade is a legendary CVD coated carbide specifically developed for Steel (P-Class). It offers high resistance to crater wear and plastic deformation, making it highly effective for stable machining. This grade is the "standard" choice for general-purpose applications where reliability is the priority over niche specialization.

SA Medium-Cut Chipbreaker

The SA chipbreaker is designed for medium-duty turning. It features a unique rake angle that balances edge strength with sharp cutting action. In CNC turning, the SA geometry ensures that chips are broken consistently, preventing "stringers" that can damage the workpiece or interfere with automated tool changers.

Recommended Cutting Parameters

Optimized for Steel (P-Class):

  • Cutting Speed (Vc): 130 - 300 m/min (425 - 980 SFM)
  • Feed Rate (f): 0.15 - 0.40 mm/rev (0.006 - 0.016 ipr)
  • Depth of Cut (ap): 1.0 - 3.5 mm

*Pro Tip: For improved tool life in harder alloys, use a stable supply of coolant and stay at the mid-range of Vc.*

"100% genuine Mitsubishi. The coating looks perfect. Delivered very quickly to our shop."

Technical Q&A

Q: Can I use UE6020 for Stainless Steel?

A: UE6020 is optimized for Steel (P-Class). For high-volume Stainless (M-Class), the MC7025 grade will provide better chemical resistance.

Q: What makes the SA chipbreaker special?

A: It is a balanced geometry. It isn't too sharp to chip, nor too dull to vibrate. It's the perfect middle ground for general CNC turning.

Q: How many cutting edges are on this insert?

A: WNMG trigon inserts are double-sided, giving you 6 usable cutting edges, making them extremely cost-effective.

Expert Machining Tip: UE6020 vs. MC6025

For General Purpose and mixed steel work, UE6020 is the standard. For Higher-Speed, continuous turning in alloy steels, upgrading to MC6025 can further increase efficiency.

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.
