Set Adjustable Bore Gages Quickly and Accurately

The Multimar 844 S Bore Gage Setting Tool from Mahr Inc. (Providence, RI) makes setting up adjustable indicating instruments, such as Mahr’s 844 N Adjustable Bore Gage and 844 T Universal ID/OD gage, quick and accurate. It uses gage block combinations and a simple hand clamping mechanism to set instruments in either the horizontal or vertical position. “Typically, adjustable bore gages are set using micrometers or master rings,” explained George Schuetz, the director of precision gages at Mahr. “But micrometers have inherent errors that can be passed along to the gage, and master rings can be expensive, especially if one is required for each of many sizes on the shop floor. Using a bore setting gage with a gage block stack assembly in a clamp with jaws at both ends provides a highly accurate reference master.” The rigid base of the Multimar 844 S Bore Gage Setting Tool is made of anodized aluminum for mobile or stationary use, either in the lab or on the production floor. Three sizes are available: 15.5 in, 45 in and 85.8 in, along with a wide range of accessories for various gage types.
