The I/m gearbox may appear to be an important factor in one's shop.
However, only sixteen of the twenty-three conventional and model maker's metric pitches are provided by this box:
0.25, 0.5, 0.75, 1.0, 1.25, 1.5, 1.75, 2.0, 2.5, 3.0, 3.5, 4.0, 4.5, 5.0, 5.5, and 6.0mm
plus many nonstandard metric pitches above and below those mentioned (see image, below).
Not provided by this box are:
0.3, 0.35, 0.4, 0.45, 0.6, 0.7, and 0.8mm
and, by extension, 0.9 and 1.2mm.
The square dial metric threading accessory provides all twenty-three conventional and model maker's metric pitches, and many others.
The I/m box certainly is a sexy feature, but it will not satisfy all metric threading needs.
