Grade: UE6020 (The Workhorse for Steel)

The UE6020 grade is one of the most reliable CVD coated carbide grades for Steel (P-Class). It is designed to resist flank wear and plastic deformation, ensuring stable machining even during moderate interruptions. Its versatility makes it the "go-to" choice for shops that require a single grade to handle various steel types with efficiency and high precision machining standards.

SA Medium-Cut Chipbreaker

The SA chipbreaker features a balanced rake angle and chip pocket width. It is specifically optimized for medium-duty turning. In CNC turning, the SA geometry prevents chip bird-nesting by breaking chips into small, manageable curls at moderate feed rates, protecting the workpiece surface and your machine's spindle.

Recommended Cutting Parameters

Optimized for Steel (P-Class):

  • Cutting Speed (Vc): 120 - 280 m/min (390 - 920 SFM)
  • Feed Rate (f): 0.10 - 0.35 mm/rev (0.004 - 0.014 ipr)
  • Depth of Cut (ap): 0.5 - 3.0 mm

*Pro Tip: For improved surface finish with a 0.4mm radius, reduce the feed rate to the lower end of the range during final passes.*

⭐⭐⭐⭐ "Dependable Performance" - Hiroshi N., Japan
"Consistent results every time. We've been using UE6020 for years and it's our first choice for steel parts."

⭐⭐⭐⭐⭐ "Best Cost per Edge" - Liam S., Australia
"With 6 usable edges, the WNMG trigon is unbeatable for value. UE6020 is very tough on the edges."

⭐⭐⭐⭐⭐ "Authentic Inserts" - Pavel D., Poland
"Received original boxes. Performance matches the Mitsubishi catalog perfectly. Very satisfied with the speed of shipping."

Technical Q&A

Q: Can I use UE6020 for Stainless Steel?

A: UE6020 is optimized for Steel (P-Class). For high-volume stainless steel turning, we recommend the MC7025 grade for better chemical stability.

Q: What is the benefit of the 0.4mm corner radius?

A: A 0.4mm radius is excellent for light to medium cutting. It reduces cutting force, which helps prevent vibration on slender parts while still providing a good finish.

Q: How many cutting edges does this insert have?

A: WNMG is a double-sided trigon, giving you 6 usable cutting edges, making it 50% more efficient than standard 4-edge diamond inserts.

Expert Machining Tip: UE6020 vs. MC6025

For General Steel turning and versatility, UE6020 is the standard. If you are doing High-Efficiency Finishing on high-alloy steels, consider upgrading to the newer MC6025 grade.

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.
