1101M-450 Dial Indicator Diameter Gage 65015

Dial Indicator Diameter Gages measure both outside and inside diameters by comparing dimensions to gage blocks or an adjustable setting master. Each gage consists of a strong rectangular box beam with a sensitive gaging contact at one end and a reference gaging contact at the other. The 1101 gages allow for measurement beyond the size range of our 1102 models. Each gage adjusts a full 6" or 150mm. The contact carriers are vertically adjustable to handle various work depths. Special contacts are available. This tool has dowel (line) contacts at one end of the gage feet, and a button (point) contact gage at the other end of the feet. These can be reversed as needed and the gaging depth can be set within a range of 2-3/4" or 70mm. This gage should be checked against our 1126 Master for a precise reference standard during production gaging. Range: 300-450mm, Graduation: .01mm

  • The sensitive contact transfers dimensions to the dial indicator through a linear friction-free mechanism
  • There are two gage feet at the reference end and one foot at the sensitive end of the gage to set the gage on the work and align the contacts
  • Gage depth is set by adjusting the gage feet up or down
  • A lever-actuated reverse mechanism loads the gage for either inside or outside diameter measurements
  • The gage contacts are easily changed to I.D. or O.D. gaging by turning them end for end
  • Unless otherwise specified, the dial indicator sent with the gage reads in .0005" increments with a total range of ±.030"
  • The dial has a double row of graduations reading in opposite directions – minus in red and plus in black


  • Range (mm): 300-450mm
  • Graduations (mm): .01mm
