MC6015 Grade Advantage
The MC6015 grade is Mitsubishi's ultimate high-speed CVD steel turning grade. The Nano-Texture coating creates an extremely smooth surface that prevents built-up edge (BUE) and allows for ultra-high cutting speeds ($v_c$). It is designed for maximum efficiency in stable machine environments.
MA Chipbreaker Logic
The MA chipbreaker is a versatile medium-cutting geometry. It balances a sharp cutting edge with high structural strength, ensuring consistent chip control across various depths of cut. This geometry minimizes thermal load on the tool tip during long-running steel turning operations.
Recommended Cutting Parameters
| Material Group | Speed ($v_c$) | Feed per Rev ($f$) | DOC ($a_p$) |
|---|---|---|---|
| Carbon Steel (S45C) | 280 - 500 m/min | 0.15 - 0.45 mm/rev | 1.0 - 4.0 mm |
| Alloy Steel (SCM440) | 220 - 400 m/min | 0.15 - 0.40 mm/rev | 0.8 - 3.5 mm |
TOOL HOLDER COMPATIBILITY
Compatible with all standard MTJNR/L or WTJNR/L external turning tool holders (Size 16).

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.
