Advanced Grade: MC5015 (Cast Iron Wear Expert)

The MC5015 grade is Mitsubishi's specialized CVD solution for gray and ductile cast iron. It features an extra-thick Al2O3 layer that provides industry-leading thermal barrier protection. This grade is specifically designed to handle the high friction and abrasive nature of iron castings, ensuring consistent performance on your CNC lathe even during continuous high-speed runs.

GK Chipbreaker Geometry

The GK chipbreaker is designed for high stability and edge reliability. Since cast iron produces short, brittle chips, the GK geometry focuses on protecting the cutting edge from sudden chipping. It is optimized for general-purpose to heavy turning, providing excellent process security even on rough casting surfaces.

Recommended Cutting Parameters

Optimized for Cast Iron (K-Class):

  • Cutting Speed (Vc): 150 - 450 m/min (490 - 1475 SFM)
  • Feed Rate (f): 0.15 - 0.45 mm/rev (0.006 - 0.018 ipr)
  • Depth of Cut (ap): 0.5 - 3.5 mm

*Pro Tip: Higher cutting speeds help the MC5015 grade's coating reach optimal efficiency.*

Global Customer Feedback

⭐⭐⭐⭐⭐ "Workhorse for Cast Iron" - David R., USA
"MC5015 is my go-to for engine blocks. The tool life is double what I was getting with my previous brand. Very impressed."

⭐⭐⭐⭐⭐ "Original & Reliable" - Stefan M., Germany
"Always trust Mitsubishi for cast iron. The GK breaker is extremely stable even with interrupted cuts on rough castings."

⭐⭐⭐⭐ "Consistency is Key" - Kenji T., Japan
"Very predictable wear patterns. Makes automated production much easier. Original Japanese quality."

⭐⭐⭐⭐⭐ "Great Value" - Lucas G., Brazil
"6 edges on a trigon insert is a life saver for the budget. MC5015 performs beautifully on ductile iron."

⭐⭐⭐⭐⭐ "Highly Recommended" - Andrej P., Poland
"Fast shipping and authentic product. These inserts stay sharp much longer in abrasive iron work."

Technical Q&A

Q: Can I use MC5015 for Stainless Steel?

A: MC5015 is specialized for Cast Iron (K-Class). For stainless steel, we recommend US735 or MC7025 grades.

Q: Is the GK chipbreaker suitable for light finishing?

A: The GK breaker is optimized for medium to heavy stable cutting. For fine finishing, you might consider the MK chipbreaker.

Q: How many cutting edges are on this insert?

A: WNMG is a double-sided trigon, providing a total of 6 usable cutting edges per insert.

Expert Machining Tip: MC5015 vs MC5005

For General Purpose Cast Iron turning, MC5015 is your best choice. If you are doing High-Speed Finishing of Gray Iron, consider MC5005 for maximum 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.
