UE6110 High-Speed Grade
The UE6110 grade is Mitsubishi's premier solution for stable steel turning at elevated speeds. It features a multi-layered CVD coating (TiCN + Al2O3) with a specialized smooth surface treatment. This reduces frictional heat and prevents plastic deformation, making it ideal for continuous, high-efficiency machining in mass production.
MA Chipbreaker Geometry
The MA chipbreaker is the industry's versatile choice for medium cutting. It is designed to provide excellent chip control across a wide range of feed rates. The geometry minimizes cutting resistance, ensuring stable performance in CNC lathe operations and reducing the risk of workpiece surface damage from chip entanglement.

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.
