SCMT09T308 UE6110
Mitsubishi Materials | The Steel Turning Specialist (CVD Coated)
The Mitsubishi SCMT09T308 UE6110 is an industry-standard indexable turning insert designed for high-efficiency steel turning. Engineered with the high-performance UE6110 CVD coating, this insert excels in continuous high-speed cutting of carbon and alloy steels. The square 90° geometry with a 7° relief angle makes it a versatile tool for both external turning and internal boring, providing a balance of wear resistance and edge toughness for stable CNC machining.

UE6110 CVD Grade
The UE6110 grade is Mitsubishi's premium CVD solution for steel. It features a thick, smooth Al2O3 layer that provides exceptional thermal stability and resistance to crater wear. This is the first choice for high-speed continuous cutting where edge reliability and extended tool life are required in carbon and alloy steels.
Medium Cut Geometry
The 08 (0.8mm) radius provides a strong cutting edge suitable for medium-duty indexable turning. It allows for higher feed rates compared to the 0.4mm radius, while still achieving excellent surface finishes. The positive rake design ensures smooth chip flow and reduced power consumption.
Recommended Cutting Parameters
Optimized for Steel (P10 - P25)

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.
