Grade: UC5115 (The Cast Iron Master)

The UC5115 grade is a specialized CVD coated carbide designed for a broad range of cast iron machining. Its high-hardness substrate combined with a thick alumina layer provides incredible resistance to the abrasive wear typical of gray cast iron. This ensures a longer tool life and reduced machine downtime.

WNMA (Flat Top) Geometry

The WNMA geometry is a flat-top, negative rake design without a chipbreaker. This is specifically intended for cast iron, which produces naturally short, fragmented chips. The absence of a chipbreaker maximizes the strength of the cutting edge, preventing premature chipping during high-speed CNC turning.

Recommended Cutting Parameters

Optimized for Cast Iron (Gray/Ductile):

  • Cutting Speed (Vc): 150 - 450 m/min (490 - 1470 SFM)
  • Feed Rate (f): 0.15 - 0.50 mm/rev (0.006 - 0.020 ipr)
  • Depth of Cut (ap): 0.5 - 4.5 mm

*Note: Ensure rigid machine clamping to achieve the best surface finish at high speeds.*

Verified Customer Feedback

⭐⭐⭐⭐⭐ "Best for high speed iron turning" - Mark T., USA
"We ran these at 400m/min on gray iron blocks. The UC5115 grade holds up where others burn out. 6 edges per insert is great value."

⭐⭐⭐⭐⭐ "Reliable and Consistent" - Klaus F., Germany
"Authentic Mitsubishi quality. Very stable dimensions even after a full shift of machining ductile iron."

⭐⭐⭐⭐ "Great surface finish" - Hiroshi S., Japan
"Clean cuts and very predictable tool life. Much better than the general purpose inserts we were using before."

⭐⭐⭐⭐⭐ "Cost-effective" - Ryan P., Australia
"Fast shipping to Perth. These WNMA inserts last forever on our lathe setup."

⭐⭐⭐⭐⭐ "Super Tough" - Antonio C., Italy
"Handles the abrasive nature of cast iron perfectly. The flat top geometry is very robust."

Technical Q&A

Q: Can I use WNMA080408 on steel parts?

A: It is not recommended. Cast iron breaks into short chips, but steel produces long ribbons. The WNMA (Flat Top) has no chipbreaker, so it won't control steel chips. Use WNMG for steel.

Q: What is the difference between UC5115 and MC5015?

A: Both are for cast iron. UC5115 is a versatile, high-speed grade, while MC5015 is often used for even higher thermal stability. UC5115 is generally the go-to for standard production.

Q: How many cutting edges do I get?

A: Since this is a negative trigon insert, you get 6 cutting edges total (3 per side).

Material Comparison Tip: UC5115 vs. UE6110

For Cast Iron Turning, always choose UC5115. It is designed to handle abrasive wear. If you are cutting Steel, switch to UE6110 or MC6025 which feature coatings optimized for crater wear resistance.

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.
