Dimensional Measuring Tools

Starrett 82 Dial bore gages are available in convenient sets or with individual probes and dial indicators. Each set consists of a dial indicator, a body and actuating rod, two adjusting wrenches and the probes as specified below. The head may be ordered separately (includes dial indicator, body, and two adjusting wrenches). Individual probes can also be ordered as listed. All probes are furnished with an actuating rod. These gages are also available with electronic indicators by special order. Measurements are taken by comparison so some type of set master should be used as a reference standard. We recommend setting as close to the hole being measured as possible, and this can be easily done with gage blocks or with a micrometer Complete Set, .560-1.565 Range .0001 Grad with Case with a micrometer.

These gages are also available with electronic indicators by special order  Useful for controlling approach to tolerance without removing the workpiece from a machine  Sets furnished in attractive, protective case  Each set consists of a dial indicator, a body and actuating rod, two adjusting wrenches and the probes  The split-ball contact is self-centering, the two-point contact detects hole geometry problems like taper, bell-mouth and out-of- roundness  Interchangeable probes are hard chrome plated and polished  All probes come complete with actuating rod  Reads to 0.002mm Range (in): 5.5 15.1mm  Graduations (in): 0.002mm  Approximate Measuring Depth (mm): 38mm and 44mm

Total measurement range of 5 to 8.125 Gradient spacing of 0.0001 Two centralizing plungers provide accurate tool alignment Two-point contact for detection of geometry problems such as ovality and taper Hardened tool steel contact points for wear resistance

Can be easily held to inspect bores and hole sizes without removing the workpiece An adjustable range screw and two centralizing plungers provide accurate, three-point contact for tool alignment in larger bores All contacts and centralized plungers are of hardened tool steel for wear and spring-loaded for sensitivity The housing and knurled handle are aluminum for light weight and good balance Dial indicators have jewel bearings for sensitivity Furnished in finished wood case Bore depths are also available up to 12 (300mm) in 1 (25mm) increments on special order Also available with carbide contacts or electronic indicators with output capability on special order
