Introduction
The standard MK8 Drive Gear have an hob diameter of 7 mm. This is the diameter of Drive Gears manufactured by [1],[2], [3] and [4]. Others manufactures offer a diameter of 7.25 mm [5] and [6] and 7.1 mm [7]. Perhaps the last option has an actual hobbed diameter slightly lower due to the bite of the teeth, but 7.25 mm is a diameter to large to be explained by the bite.
I was wondering if this difference in diameter is due to the tap used to hob the gear's groove.
