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.
| Offset | Value "A" |
| 5/16" (see note) | .3125 |
| 1/2" | .5 |
| 5/8" | .625 |
| 1" | 1 |
| 10 mm | 10MM |
| 12 mm | 12MM |
| 20 mm | 20MM |
| 25 mm | 25MM |
*Note: For adapters having an offset of 5/16" (.3125"), choose a "B" dimension of .250" (6.25 mm) or greater. Shank diameters smaller than .250" cannot be manufactured with a magnet.
| Shank Diameter | Value "B" | Shank Diameter | Value "B" |
| 0.100" | .1 | 4 mm | 4MM |
| 1/8" | .125 | 5 mm | 5MM |
| 5/32" | .156 | 6 mm | 6MM |
| 3/16" | .1875 | 7 mm | 7MM |
| 1/4" | .25 | 8 mm | 8MM |
| 9/32" | .2812 | 9 mm | 9MM |
| 5/16" | .3125 | 10 mm | 10MM |
| 3/8" | .375 | 12 mm | 12MM |
| 7/16" | .4375 | ||
| 1/2" | .5 |
*Note: Some configurations (like the 5/16") cannot be manufactured with a magnet, due to size restrictions.
