When choosing an indexable insert, please also pay attention to its microgeometry, which is indicated by icons directly in the catalogue section. Below is an overview of the types of cutting edges you can find on our inserts.

Overview of Cutting Edge Designs

cutting edge GAMO face

F Sharp cutting edges – recommended for inserts designed for use with milling cutters for Al alloys. Sharp cutting

flank BETO wedges result in minimal deformation of the cut layer, reduced build-up on the edge and a lower cutting force

ALO requirement. However, the strength of the cutting wedge is lower compared to other types. cutting wedge

Rounded cutting edges – a slight rounding of the wedge with the aim of eliminating micro-imperfections on its

surface. Rectifying the wedge at a certain very low radius (RE) improves the cutting edge's resistance to mechanical

damage, i.e. brittle fracture or so-called micro-crumbling. This modification is currently used on all indexable inserts without a facet (F modification previously), which are used for milling almost all types of material.

cutting edge face BN facet g GAMOGAMO x Faceted cutting edges – a facet with width of x and angle of γ increases the angle γ of the cutting wedge in the T immediate vicinity of the cutting edge, thus also increasing its strength, i.e. its resistance to mechanical load, brittle xn

Rounded edges with facet – compared to the T modification, the insert has undergone rectification which

results in rounding of the cutting edge and thickening by a facet. This modification increases the resistance of the

wedge against mechanical damage to a greater degree.
