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

Are your carbide inserts interchangeable with major brands like Sandvik, Iscar, or Kennametal?

Absolutely. Our CNC carbide inserts (including CNMG, WNMG, DNMG, and APMT series) are manufactured strictly adhering to international ISO/ANSI specifications. A CNMG 120408 from OYYU BEYOND will flawlessly fit any standard turning tool holder or indexable tool from major global brands like Sandvik Coromant, Kennametal, Iscar, Walter, or SECO, providing a highly cost-effective premium alternative without sacrificing tolerance or tool life.

How do I choose the correct insert grade and chipbreaker for machining Stainless Steel (M) vs. Carbon Steel (P)?

We offer optimized CVD and PVD multi-layer coatings for different ISO material groups:

  • For Carbon/Alloy Steel (ISO P): Choose our thick multi-layer CVD coated grades (e.g., Al2O3 + TiN). They provide exceptional crater wear resistance and thermal barriers during high-speed dry or wet roughing.
  • For Stainless Steel (ISO M): Choose our nano-structured PVD coated grades with sharp, positive chipbreakers (like -TM or -MA). This combination prevents work hardening and effectively controls sticky chips.
What are the recommended cutting speed (Vc) and feed rate (f) parameters to maximize tool life?

The optimal cutting parameters vary depending on the workpiece hardness and operation type:

  • For General Steel Turnings: Recommended cutting speed ($V_c$) ranges from 150 to 280 m/min, with a feed rate ($f$) of 0.15 to 0.45 mm/rev.
  • For Stainless Steel Finishing: Recommended cutting speed ($V_c$) is 120 to 200 m/min, with a feed rate ($f$) of 0.10 to 0.25 mm/rev.Always adjust parameters based on early wear patterns: increase $V_c$ if built-up edge occurs, or reduce $V_c$ if severe flank wear is observed.
Do you offer bulk discounts or wholesale pricing for machine shops and distributors?

Yes, we support machine shops, distributors, and global buyers with tiered wholesale pricing and competitive volume discounts. We also provide OEM custom manufacturing solutions for tool holders and carbide inserts based on your technical drawings. Contact our team to request a quick B2B quotation.

What is your international shipping policy and typical lead time for orders?

We provide secure worldwide express shipping (via DHL, FedEx, and UPS) with specialized, vibration-proof industrial packaging to ensure tools arrive in perfect condition. In-stock items are dispatched within 24-48 hours, while custom or bulk orders typically have a stable lead time of 15-25 days.

How do you guarantee the quality and tolerance precision of your CNC tools?

All our cutting tools and tool holders are manufactured strictly in accordance with ISO 9001 and international industrial standards. Every batch undergoes 100% rigorous quality control testing using high-precision optical measuring equipment to ensure reliable tool life and stable performance in continuous mass production.
