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

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.
