Gear tool profiles are often custom-made for a specific gear. That is, the tooth space size and shape must be an exact match to the tool.

Important considerations when ordering gear milling cutters:

Module size

Pressure angle

Gear tooth profile (with root clearance, tooth tip profile or tooth tip chamfer)

Modulation factor

Tooth tip and root diameter

Helix angle

Gear quality requirements

Possible tool diameter range (min-max)

Interface type and size
