Advanced Grade: UE6020 (The Steel Specialist)

The UE6020 grade is Mitsubishi's benchmark for high-speed steel turning. It features a specialized CVD coating layer that resists crater wear and thermal fatigue. This grade is specifically designed to handle the high temperatures generated during continuous cutting of carbon, alloy, and tool steels, ensuring maximum tool life and process reliability on your CNC lathe.

MS Chipbreaker Geometry

The MS (Medium-Sharp) chipbreaker is designed for light-to-medium cutting. For steel machining, the MS geometry is critical for managing chip control and preventing surface damage. The sharp cutting edge reduces cutting force, making it ideal for thin-walled parts or finishing passes where high precision is required.

Recommended Cutting Parameters

Optimized for Steel (P-Class):

  • Cutting Speed (Vc): 150 - 300 m/min (490 - 980 SFM)
  • Feed Rate (f): 0.10 - 0.30 mm/rev (0.004 - 0.012 ipr)
  • Depth of Cut (ap): 0.3 - 2.5 mm

*Pro Tip: Ensure rigid tool clamping and optimal spindle speeds to fully utilize the high-speed potential of the UE6020 grade.*

Global Customer Feedback

⭐⭐⭐⭐⭐ "Workhorse for Mild Steel" - Robert B., Canada
"UE6020 is my top choice for 1018 and 1045 steel. It stays sharp through long production runs and the finish is excellent."

⭐⭐⭐⭐⭐ "Very Sharp Edge" - Juergen S., Germany
"The MS breaker works wonders on light cuts. It provides a very clean surface finish without the chatter you get from duller inserts."

⭐⭐⭐⭐ "Great Chip Control" - Yuki M., Japan
"Chips break perfectly in alloy steel. Very reliable performance for our automated CNC processes."

⭐⭐⭐⭐⭐ "Value for Money" - Steve P., UK
"Authentic Mitsubishi parts. 6 edges per insert makes it much more economical than standard diamond shapes."

⭐⭐⭐⭐⭐ "Top Grade" - Mateo L., Italy
"Fast shipping and original packaging. These inserts perform better than any generic brand I've tried in the shop."

Technical Q&A

Q: Can I use UE6020 for Stainless Steel?

A: While it can cut some stainless, UE6020 is optimized for Steel (P-Class). For stainless steel, we recommend the US735 or MC7025 grades.

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

A: The 0.4mm (04) radius is ideal for precision finishing and reduces cutting pressure, which helps prevent vibration in long parts.

Q: Is this insert compatible with a DNMG holder?

A: No, WNMG requires a specific 80° trigon holder like MWLNR or DWLNR. It is not interchangeable with diamond holders.

Expert Machining Tip: UE6020 vs MC6025

For Continuous Steel Cutting at high speeds, UE6020 is a proven classic. If you face Interrupted Cuts or need more edge toughness, consider the 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.
