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

How do I choose the correct specification?

When choosing CNC cutting tools, check the full model code, dimensions, grade and selected variant before ordering. Do not rely on the product image alone.

How can I check compatibility with my existing setup?

For carbide inserts, tool holders, drills and end mills, compare the mounting dimensions, connection type and manufacturer's specifications with your holder or machine. If you are unsure, share your existing part number and machining application with us before ordering.

What quantity and price unit am I ordering?

Check the product listing for the selling unit, pack quantity and included components. If it is unclear whether the price is per piece or per pack, or whether a tool body and inserts are sold separately, contact us before purchasing.

How should I choose cutting parameters?

Select cutting speed, feed rate and depth of cut using the relevant manufacturer's recommendations for your tool model, workpiece material, machine conditions and coolant method. The same settings are not suitable for every product or application.

Are bulk discounts available?

Our automatic quantity discount is 6% off for 2–9 items and 12% off for 10 or more items, based on the total product quantity in the cart. Other offers may not combine with this discount; check the applicable offer conditions.
