Grade: UC5105 (High-Speed Continuous Master)

The UC5105 grade is Mitsubishi's ultimate solution for gray cast iron. It utilizes an ultra-hard CVD coating optimized for continuous cutting at high surface speeds. This grade provides superior protection against the abrasive nature of Cast Iron (K-Class) turning, preventing premature flank wear even in extreme heat. For precision machining of engine blocks, brake discs, and industrial housings, UC5105 is the gold standard.

Stable Geometry for Productivity

The 80° trigon shape of the WNMG080408 provides a robust edge strength that is much more durable than standard 55° or 35° diamond inserts. In CNC machining, this means you can achieve higher metal removal rates while maintaining 6 usable cutting edges per insert, drastically lowering your cost-per-part.

Recommended Cutting Parameters

Optimized for Gray Cast Iron (K-Class):

  • Cutting Speed (Vc): 200 - 500 m/min (650 - 1640 SFM)
  • Feed Rate (f): 0.15 - 0.45 mm/rev (0.006 - 0.018 ipr)
  • Depth of Cut (ap): 1.0 - 4.0 mm

*Pro Tip: UC5105 is designed for speed. To prevent chip welding and ensure best tool life, maintain a high cutting velocity (Vc).*

Global Verified Customer Feedback

⭐⭐⭐⭐⭐ "Incredible Wear Resistance" - Markus R., Germany
"We were replacing inserts every 30 brake discs with our old grade. With UC5105, we hit 75 before a change. Outstanding Japanese quality."

⭐⭐⭐⭐⭐ "High Speed, No Issues" - James W., USA
"Running these at 450 m/min on gray iron. The finish is consistent and the wear pattern is very predictable. Great value for CNC work."

⭐⭐⭐⭐ "6 Edges is a Winner" - Akira H., Japan
"Trigon inserts are so much more stable than CNMG for our roughing passes. UC5105 grade is very tough."

⭐⭐⭐⭐⭐ "Predictable Tool Life" - Steve B., UK
"Original Mitsubishi product. Perfect for automated shifts where we need consistent performance to avoid crashes."

⭐⭐⭐⭐⭐ "Fast Shipping" - Andrei V., Poland
"Authentic inserts. Packaged well and arrived on time. The high-speed capability really helped our production lead times."

Technical Q&A

Q: Can I use UC5105 for Ductile Iron?

A: Yes, it can be used, but UC5105 is primarily optimized for continuous high-speed Gray Iron. For interrupted cuts or heavy-skin Ductile Iron, the UC5115 grade might offer more toughness.

Q: What is the benefit of the trigon shape?

A: The WNMG shape provides a larger wedge angle than diamond shapes, giving it more strength for heavier cuts while still providing 6 cutting edges.

Q: Do these come in original packaging?

A: Yes, all our Mitsubishi inserts are 100% original, Made in Japan, and come in factory-sealed boxes of 10.

Expert Machining Tip: UC5105 vs. UC5115

For Continuous High Speed on gray iron, UC5105 is unbeatable. If your setup is unstable or you have interrupted cuts, choose UC5115 for extra edge toughness.

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.
