Starrett 1100-18-1 Heavy-Duty Dial Indicator Diameter Gage, 12-18", .0001"

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 combine heavy-duty construction features with adaptability for a wide range of internal and external measurements. The adjustable dowel rest legs ride on slotted mounting plates for horizontal adjustment. Each of the legs are vertically adjustable to obtain the proper rest position on the work and correct alignment on the gaging contacts. 2" or 50 mm range vertical adjustment. Radiused gaging contacts. The indicator can be rotated through to 360 Deg for a convenient gage should be checked against our 1126 Master for a precise reference standard during production gaging. Range: 12-18", Graduation: .0001"
