RCMX1204MO UE6110
Mitsubishi Materials | Heavy-Duty Round Insert for Steel Profiling
The Mitsubishi RCMX1204MO UE6110 is a heavy-duty round turning insert engineered for maximum stability in steel machining. With a 12mm diameter, this R-type insert is the primary choice for profiling, copy turning, and high-volume metal removal. Utilizing the advanced UE6110 CVD coating, it provides an industry-leading balance of wear resistance and edge toughness, making it indispensable for stable CNC turning of carbon and alloy steels.

UE6110 Grade Performance
The UE6110 grade is Mitsubishi's premium CVD coated carbide optimized for the P10-P20 range. It features a specialized thick Alumina layer that acts as a thermal shield, allowing for high-speed turning without compromising tool life. This grade is specifically designed to resist crater wear and plastic deformation when machining steel under continuous load.
MO Chipbreaker Design
The MO geometry is a medium-duty chipbreaker that provides a reinforced land for high-impact resistance. In indexable turning, the round RCMX shape allows for variable lead angles; the MO geometry ensures that chip control remains consistent whether you are performing a deep facing cut or a shallow profiling pass, reducing cutting resistance and harmonics.

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.
