Fits 1/8" - 3/8" and 4 mm - 10 mm diameter holes

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 4 mm to 10 mm.  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" (0.013 mm).  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.
