MC5015 Grade Technology
The MC5015 grade is optimized for high-speed continuous turning. The Nano-Texture Al2O3 coating ensures uniform crystal growth, providing a harder surface that resists crater wear and heat buildup during long production runs in abrasive cast irons.
GK Chipbreaker Profile
The GK chipbreaker is the first choice for stable Cast Iron (K) turning. It features a robust land area that enhances cutting edge strength, effectively managing chips even when machining brittle materials like Gray Cast Iron (GCI).
Optimization: Cutting Parameters
| Material Group | Cutting Speed ($v_c$) | Feed Rate ($f$) |
|---|---|---|
| Gray Cast Iron (GCI) | 200 - 450 m/min | 0.10 - 0.40 mm/rev |
| Ductile Cast Iron (FCD) | 150 - 300 m/min | 0.10 - 0.35 mm/rev |

Technical FAQ & Buying Guide
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.
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.
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.
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.
