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

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.
