The 0.5TH series of magnetic adapters provide nests (for
1/2" diameter SMRs) which mount in holes having diameters from 1/8" -
3/8", and from 4mm to 10mm. Shank diameters are held to very
close tolerances for precision slip fits. The
adapter holds the centerpoint of a 0.5" diameter SMR on
centerline of the shank to a tolerance of ±0.0005"
(0.013mm). Shank diameters are held to very close
tolerances for precision slip fits. Various diameters
and offsets are available - see table below for
descriptions and part numbers.
Choose any "A" value from the table (below), and pair
with any "B" value (below, right) to create the item number for the product that
you want, for example, 0.5TH-25MM-.375.
