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.*

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

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.
