Material: NX2525 Cermet Grade
The NX2525 grade is a premium uncoated cermet known for its exceptional chemical stability at high temperatures. Unlike traditional tungsten carbide, cermet has a low affinity for steel, which virtually eliminates built-up edge (BUE). This makes it the ideal material for high-speed finishing where maintaining precise tolerances and a glossy surface finish is the primary objective.
Geometry: W-Type (Flat Top with Hole)
The W-Type geometry refers to a flat-top face with a countersunk mounting hole. This design is optimized for screw-on milling cutters. Because there is no molded chipbreaker, the cutting edge is incredibly sharp and strong, perfect for light depths of cut and high-feed finishing paths.
Recommended Cutting Parameters

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.
