Mahr Federal 1280 P adjustable bore gages feature rugged construction for long life and low maintenance, including a stainless steel gaging head and one piece centralizing yoke with replaceable tungsten carbide balls. Furnished with either a dial or digital indicator and available with integrated wireless data transmitters, 1280 P bore gages are sized to measure diameters from 12 – 200 mm (0.50 – 8″) with extensions, and depths from 76 – 1220 mm (3 – 48″).

Also available with integrated wireless transmission, Mahr Federal’s precision self-centering 844 N adjustable bore gages are virtually impervious to temperature changes as both the shank and transfer rod are made from Invar steel. Extremely versatile and quick to adjust to any size within their range, 844 N bore gages can be used to measure diameter, roundness, and conical form, as well as the distances of plane-parallel surfaces of tight tolerance parts. Able to measure diameters from 18 – 800 mm (0.7 – 32″), they provide low hysteresis and high repeatability.

Mahr Federal 300 P snap gages provide fast precise OD measurement on the shop floor. Available over a wide range of sizes, styles and readout configurations, they provide measuring capacity from 0 – 508 mm (0 – 20″) and are available with integrated wireless transmitters and dial or digital indicators. A unique “Channel Lock” design assures precisely parallel anvil surfaces, with positive position locking at any point within the range.
