Material & Geometry Mastery
UC5115 Coating Technology
The UC5115 CVD grade is engineered for extreme wear resistance. Its thick Alumina (Al2O3) coating provides a superior thermal barrier, allowing for stable, high-speed dry machining of abrasive cast irons without the risk of plastic deformation.
MA Chipbreaker Logic
The MA (Medium-range) chipbreaker is the workhorse of the industry. With a 1.2mm radius, the DNMG150612 version offers enhanced edge security, preventing chipping even during light interrupted cuts or when dealing with scaly cast iron surfaces.

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.
