UE6110 CVD Grade
The UE6110 grade is Mitsubishi's premier CVD (Chemical Vapor Deposition) coated carbide for high-speed turning of steel. The multi-layer coating provides a hard barrier against heat and chemical wear, making it extremely reliable for continuous cutting. It is the go-to for workshops prioritizing stable tool life over gloss.
Chipbreaker Performance
The TCMT positive geometry combined with Mitsubishi's advanced chipbreaker design ensures smooth chip evacuation across a wide range of feed rates. The 0.4mm radius provides a perfect balance of edge strength and the ability to produce fine surface finishes during finishing and semi-finishing passes.

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.
