GC4425 Grade Technology
The GC4425 grade is Sandvik's latest generation steel turning solution. Featuring Inveio® technology, the uni-directional crystal orientation in the alumina coating layer provides extreme wear resistance and thermal protection, making it the top choice for long tool life in ISO P25 steel applications.
-MR Chipbreaker Geometry
The -MR (Medium Roughing) geometry is engineered for stability. It is a robust chipbreaker designed to handle heavy machining and varying depths of cut. It ensures reliable chip evacuation even in tougher, scaled surfaces of forged or cast steel components.

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.
