MITSUBISHI WNMG060408-MA US735

Professional Stainless Steel Specialist | High-Toughness CVD Coating

Product Overview

The Mitsubishi WNMG060408-MA US735 is a premium, double-sided 80° trigon negative insert designed for the high-efficiency machining of stainless steel. Utilizing the legendary US735 CVD coated grade, this insert provides exceptional resistance to thermal cracking and notch wear, which are common obstacles when turning austenitic stainless steels. Equipped with the MA chipbreaker, it is the industry standard for medium-duty CNC lathe operations, ensuring stable chip control and prolonged tool life in challenging conditions.

Grade & Geometry: US735 Stainless Specialist

The US735 grade is a specialized carbide substrate paired with a tough CVD coating, specifically balanced for interrupted cuts and high-temperature environments. It prevents built-up edge (BUE) and excels in work-hardening materials. The MA chipbreaker is a versatile medium-cutting geometry that balances edge sharpness with strength, providing excellent chip breaking across a wide range of precision machining applications.

Recommended Cutting Parameters

Optimized for Stainless Steel (M-Class):

  • Cutting Speed (Vc): 80 - 180 m/min (260 - 590 SFM)
  • Feed Rate (f): 0.15 - 0.40 mm/rev (0.006 - 0.016 ipr)
  • Depth of Cut (ap): 0.8 - 3.5 mm

*Pro Tip: For best results, use a generous supply of coolant to manage heat dissipation.*

Customer Reviews & Feedback

⭐⭐⭐⭐⭐ "Reliable for 316 Stainless" - James P., USA
"The US735 grade is my go-to for 316 stainless. It handles the toughness without chipping, and the 0.8mm radius gives a great balance between tool life and finish."

⭐⭐⭐⭐⭐ "Authentic Quality" - Stefan M., Germany
"Original Mitsubishi packaging. These inserts are very consistent. Excellent performance for medium turning operations."

⭐⭐⭐⭐ "Great Chip Control" - Tanaka H., Japan
"The MA chipbreaker works perfectly in a variety of stainless grades. No bird-nesting of chips on my CNC lathe."

⭐⭐⭐⭐⭐ "Superb Value" - Liam R., Australia
"6 usable edges per insert makes these very cost-effective. Shipping was fast and the product is top-notch."

⭐⭐⭐⭐⭐ "Tough Tooling" - Ricardo S., Brazil
"Even in interrupted cuts on stainless shafts, the US735 holds its edge. Very satisfied with the durability."

Technical Q&A

Q: Is WNMG060408 suitable for roughing or finishing?

A: With the MA chipbreaker and a 0.8mm radius, it is best suited for medium-duty cutting. It can handle light roughing but is designed for general purpose efficiency.

Q: How many cutting edges are available?

A: This is a double-sided negative trigon insert, giving you 6 usable edges total (3 per side).

Q: Does US735 require coolant?

A: While it can run dry, high-pressure coolant is highly recommended for stainless steel to prevent heat build-up and improve chip evacuation.

Expert Tip: Material Comparison

For Stainless Steel, use US735 for its toughness. If you are predominantly machining Cast Iron, we recommend switching to UC5115 for better abrasive resistance. Always match the grade to the material class for maximum tool life.

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.
