Starrett 55948 Dial Indicator Base Kit Magnetic Base

Product Description

The STARRETT 55948 is a dial indicator base kit designed for precision measurement in shop, field, and maintenance applications. It pairs a heavy-duty magnetic base with a dial indicator featuring a 0-25-0 balanced dial reading and a graduation of 0.0005 decimal inches (0.01 mm). The 2-1/4-inch diameter dial provides clear graduation visibility. The upright post assembly stands 9-3/8 inches tall with a 3/4-inch diameter post, giving technicians flexible positioning for runout checks, surface comparisons, and alignment work. The complete kit weighs 5 pounds and ships as a 2-piece set including the base, indicator, and upright post assembly.

This kit suits precision measurement tasks in machine shops, industrial maintenance, and field service environments. Typical applications include shaft runout inspection, surface plate work, fixture alignment, and checking tolerances on machined components. The magnetic base attaches securely to ferrous surfaces, making it practical for use directly on machine tables, lathe beds, and steel fabrication fixtures. Machinists, millwrights, and maintenance technicians are the primary users of this type of kit.

Installation Notes

Installation requires no special tools beyond positioning and activating the magnetic base. Ensure the mounting surface is clean, flat, and free of chips or coolant before engaging the magnet to achieve full holding force. The indicator tip and post assembly should be secured snugly before taking measurements to prevent deflection errors. Follow your facility or shop safety procedures when working near rotating machinery or energized equipment.
