Describes the nominal dimensions of general-purpose single-start solid (monobloc) gear hobs with axial keyway or tenon drive of 0,5 to 40 module.

This International Standard specifies the nominal dimensions of general-purpose single-start solid (monobloc) gear hobs with axial keyway or tenon drive of 0,5 to 40 module.

These hobs are intended for the production of gears which conform to ISO54 and present a 20° pressure angle in conformity with ISO53.

NOTE Solid hobs are those made from one solid piece of material, as opposed to hobs which have inserted blades.
