This standard provides specifications for nomenclature, dimensions, tolerances, and inspection for gear hobs for modules 0.63 to 40 mm. It establishes a basis for understanding the use and manufacture of these tools.
Application
This standard applies to single and multiple-thread hobs for spur and helical gears.
Exceptions
This standard is not intended to completely define the hob tooth profile as it relates to the exact gear profile. It is advisable to check gear tooth profile specifications with the hob manufacturer involved. Examples include cutting depth and hob tooth profile modification as they affect gear tooth tip relief for fine-pitch and coarse-pitch hobs.
Where conditions require use of hobs of special design or specifications, such hobs shall be considered beyond the scope of this standard.
