MITSUBISHI WNMG06T312-MA US735

Heavy-Duty Stainless Specialist | Superior CVD Edge Strength

Product Overview

The Mitsubishi WNMG06T312-MA US735 is an industrial-grade, double-sided 80° trigon negative insert optimized for heavy-duty stainless steel turning. Engineered with a large 1.2mm nose radius and the specialized US735 CVD coating, this insert excels in high-feed applications and interrupted cuts. The MA chipbreaker provides the necessary edge stability to handle work-hardening materials like 304 and 316 stainless, ensuring maximum productivity in CNC lathe operations.

Material Excellence: US735 CVD Technology

The US735 grade is a specialized CVD-coated carbide designed for tough, adhesive materials. It features a high-toughness substrate that resists the thermal shock common in stainless steel turning. This grade effectively prevents notch wear and built-up edge (BUE), maintaining dimensional accuracy over long production runs.

MA Chipbreaker & 1.2mm Radius

The MA chipbreaker is designed for a broad range of medium-duty applications. When paired with the 1.2mm radius, this indexable insert becomes a powerhouse for roughing. The large radius distributes cutting forces over a wider area, significantly increasing tool life and allowing for higher feed rates without sacrificing edge integrity.

Recommended Cutting Parameters

Optimized for Stainless Steel (M-Class):

  • Cutting Speed (Vc): 70 - 160 m/min (230 - 525 SFM)
  • Feed Rate (f): 0.18 - 0.45 mm/rev (0.007 - 0.018 ipr)
  • Depth of Cut (ap): 1.0 - 4.0 mm

*Pro Tip: Higher feed rates are encouraged with the 1.2mm radius to ensure proper chip breaking.*

Verified Global Customer Feedback

⭐⭐⭐⭐⭐ "Beast for roughing" - Robert H., USA
"The 1.2mm radius on these US735 inserts is a game changer for roughing 304. Much more stable than the 0.8mm."

⭐⭐⭐⭐⭐ "Original Quality" - Klaus M., Germany
"Genuine Mitsubishi inserts. The CVD coating is very tough against thermal cracking. Very reliable."

⭐⭐⭐⭐ "Great for Interrupted Cuts" - Sato Y., Japan
"Stable tool life even when the cut is not continuous. The MA geometry handles chips well."

⭐⭐⭐⭐⭐ "Cost-Efficient" - Liam N., Australia
"Getting 6 edges out of one insert makes these very economical for our shop operations."

⭐⭐⭐⭐⭐ "Precision on Stainless" - Alessandro V., Italy
"Excellent resistance to built-up edge. My parts come out with consistent dimensions every time."

Technical Q&A

Q: Why choose the 1.2mm radius over 0.8mm?

A: The 1.2mm radius offers superior edge strength, making it ideal for heavy roughing and higher feed rates in stainless steel.

Q: Is this insert double-sided?

A: Yes, it is a negative trigon insert, providing 6 usable cutting edges total.

Q: Does it work on duplex stainless steel?

A: Yes, the US735 grade is designed for tough stainless alloys, including duplex, where high toughness is required.

Expert Material Tip: US735 vs. MC7025

For General Stainless Steel turning with vibrations or interruptions, choose US735. For high-speed continuous turning where tool life is the priority, consider MC7025.

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.
