• The perpendicularity & surface roughness will vary depending on the cutting conditions, material, machine tool & workpiece rigidity.

APPLICATION ADVICE In 90º corner milling, the insert with a positive shape and large rake angle reliably curls the cutting chips, increasing the evacuation performance. The high rake insert used in the FULLCUT MILL will be helpful.

SURFACE MILL CUTTER DIAMETER: Ø80 FACE MILL CUTTER Exhibits difference in the top surface finish of the workpiece.

APPLICATION ADVICE Glossiness of the machined surface with a face cutter is affected by the sharpness of the insert. By using different cutters between roughing and finishing operations, not only can a smooth surface finish be achieved, but the life of the insert can also be easily managed to obtain stable quality.
