Roughing end mill Dormer Tools

Tests were carried out to compare the new S333 roughing cutter with a standard roughing cutter on AMG 1.5. On the S333, the combination of the toughness properties of the carbide material, the Super-G coating and the geometry of the tool (unequal helix, asymmetric chipbreaker profile) resulted in less tool vibration and less wear on the tool, compared to the standard roughing cutter. Consequently for the S333, the quality of the surface finish of the workpiece is higher and the tool life of the cutter is over 30% longer, resulting in less tool changes.
