About
The 1.5TH Series magnetic adapters provide an SMR nest which mounts in holes having a diameter of 1/8" - 5/8" or 4 mm to 15 mm. Shank diameters are held to close tolerances (-0.0001" to -0.0005") for precision slip fits. The adapter holds the centerpoint of a 1.5" diameter SMR 1.000" (or 25 mm) above the surface of the part and on centerline of the shank to a tolerance of ±0.0005" (0.013 mm). The SMR seats on a 3-point conical land and is held in place by a magnet. An optical alley allows the SMR to be rotated down for a lower shooting angle. Construct the desired part number using the information below, or make up your own - we don't have room to show all possible sizes!
Choose an "A" value below, and pair with desired "B" value to create the item number for the product that you want, for example, 1.5TH-1-.375.
