1175, 1175M Dial Indicator Groove Gages
.375-6" / 9 .5-150mm

This lightweight gage is used for in-process or bench inspection of oil grooves, snap ring
retainer grooves, “O” ring seat retainer grooves and similar internal recesses . It is also useful for checking bore dimensions and testing for taper, bell-mouth and out-of-roundness. The movable, sensitive gaging contact has a 1/2" (12 .7mm) retractable range and transfers the measurement through a linear, friction-free transfer mechanism to the dial indicator . The lower reference jaw is fixed and supports the entire weight of the gage and the operator’s hands, thus preventing incorrect gaging pressure and false readings .
The reference jaw can be mounted in two positions on the range adjusting bar . The bar itself is also adjustable for greater or lesser range . A fine adjustment screw and a lock are also provided .

Features:

• Supplied with two sets of jaws, both readily interchangeable
• Three sets of contacts are furnished (Styles 1-10, 2-10, 2-20) that can be attached to the ends of the jaws without replacing the entire jaw . Contacts have flush ends so that grooves at the bottom of blind holes can be gaged . The contacts are hardened steel with a hard chrome finish for long life
• Gage can be set with gage blocks or other methods such as micrometers, vernier
  calipers and ring gages
• Furnished with storage case
• Special jaws for 4" and 6" (100mm and 150mm) gaging depths, a diameter range extension bar from 6-12" (150-300mm), dial indicators graduated in .001", or any special modification of gaging contacts and jaws, are also available by request through our Special Order Department
