In addition to the standard program, special dimensions and versions are also supplied for all types of saw machines.


Geometries for different applications

A: Standard tooth form for fine-toothed saw blades with a pitch of T = 0.8 - 3.0 mm

AW: Like tooth form A but with side chamfer


HZ (C): forward and trailing cut tooth, for the cutting of solid material, pipes and  profiles with heavier wall thicknesses (>3 mm)


B: Tooth form for narrow cut saw blades with a thickness <1.3mm

BW: Tooth form for tubes and profiles with thin wall thicknesses


BS: Standard tooth form for tubes and profiles


Cutting value recommendations

Selection of the proper cutting parameters depends on the material to be cut, the material cross section, the cooling and lubrication, the tooth geometry to be used, the condition of the sawing machine, as well as the surface treatment and coating of the saw blade. The values listed below are to be used as practical guidance aids.
