Bore Gages
• This is a bore gage for measuring .7 to 6.5 in inside diameters. • With a short length below the grip, a lightweight and easy-to-handle body makes it easier to insert the gage in a narrow space or perform measurements on a table. • Carbide-tipped contact point and anvil for durability and wear resistance.
