MITSUBISHI WNMG060404-MA US735

The Stainless Steel Specialist | Toughened CVD Coated Carbide

Product Overview

The Mitsubishi WNMG060404-MA US735 is a high-performance, double-sided 80° trigon negative insert designed specifically for machining stainless steel. Utilizing the advanced US735 CVD coating, this insert offers exceptional resistance to thermal cracking and notch wear, which are common challenges in austenitic stainless steel turning. Equipped with the MA chipbreaker, it is the premier choice for medium-duty CNC lathe operations, ensuring stable chip control and extended tool life in demanding conditions.

Material Grade: US735 (Stainless Specialist)

The US735 grade is a specialized CVD coated carbide designed for interrupted cutting and heavy-duty machining of stainless steel. Its unique multi-layer coating provides excellent resistance to built-up edge (BUE) and work hardening, which are typical issues when turning materials like 304 or 316 stainless steel. This results in consistent precision machining and high reliability.

MA Chipbreaker Performance

The MA chipbreaker is an all-rounder for medium-range cutting. It balances sharp edge performance with strength, providing excellent chip control across a wide range of feed rates. This prevents "bird-nesting" of chips, protecting both the workpiece surface and the indexable tool holder.

Recommended Cutting Parameters

Optimized for Stainless Steel (M-Class):

Cutting Speed (Vc): 80 - 180 m/min (260 - 590 SFM)
Feed Rate (f): 0.12 - 0.35 mm/rev (0.005 - 0.014 ipr)
Depth of Cut (ap): 0.5 - 3.0 mm

*Pro Tip: Ensure sufficient coolant flow to prevent heat buildup on the stainless steel surface.*

Verified Customer Feedback

⭐⭐⭐⭐⭐ "Perfect for 304 Stainless" - Robert T., UK
"I was struggling with chip control on 304, but these MA chipbreakers work like a charm. US735 grade lasts much longer than my previous inserts."

⭐⭐⭐⭐⭐ "Original Mitsubishi Quality" - Marco L., Italy
"Consistent performance in every box. Use these for medium turning and they never disappoint. Fast shipping!"

⭐⭐⭐⭐ "Great Chip Control" - Kenji S., Japan
"Stable tool life in interrupted cuts. The MA geometry is very versatile for various stainless grades."

⭐⭐⭐⭐⭐ "Cost-Effective" - David M., USA
"6 usable edges make these very economical for our shop. US735 is tough."

⭐⭐⭐⭐⭐ "Reliable Delivery" - Andrej P., Poland
"Original packaging and performance is as expected from Mitsubishi. My go-to for CNC turning."

Technical Q&A

Q: Can I use US735 for turning regular carbon steel?

A: While it can cut steel, US735 is optimized for the toughness of stainless steel. For general steel, MC6025 is typically more efficient.

Q: How many cutting edges does this insert have?

A: This is a negative trigon insert, providing a total of 6 cutting edges (3 per side).

Q: What is the main difference between MA and MS chipbreakers?

A: MA is for medium cutting, while MS is optimized for finishing and lighter depths of cut.

Stainless Steel Turning Tip

Stainless steel tends to work-harden quickly. To maximize tool life, always maintain a consistent feed rate and ensure your depth of cut is greater than the work-hardened layer from the previous pass.

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.

When will my order ship and arrive?
