Fowler X-Tender Dial Bore Gage Kit

The Fowler Dial Bore Gage Set has a measurement range of 1.4 to 6 inches. Manufactured by the American company Fowler High Precision, this product comes with a 1-year warranty. Bore gages are used to measure the interior diameter of holes or bores in a workpiece at any depth, unlike internal micrometers which can only measure to the depth of their anvils.

There are two types of bore gages: simple and direct measuring. Simple bore gages are used with a caliper to transfer the hole measurement, while the more complex direct measuring gages provide the measurement directly through a vernier, dial, or digital display. Bore gages have either a two-point or three-point contact, which indicates how many points on the gage head touch the inside of the bore. Two-point contacts are better for measuring ovality, while three-point contacts are used to measure lobing or triangular form error.

Pistol-grip bore gages are designed for fast, single-handed operation and provide repeatable results from one operator to another. Fowler, founded in 1946 and headquartered in Newton, MA, is a renowned manufacturer of premium inspection and measuring instruments, including electronic indicators, calipers, bore gages, and micrometers.

The Fowler Dial Bore Gage Set features a dial indicator graduated in 0.0001 inch and has a measuring depth of 9.5 inches. The chrome-plated handle and two-point contact system are durable and can be used to detect geometry problems such as ovality and taper. The carbide-tipped contact points provide extended wear and improved abrasion resistance.

The bore gage is self-centering and includes a 2-inch contact extension holder, making it easily adjustable. The set comes with 2 self-centering measuring heads, an extension holder, 15 anvils, 4 spacers, and a fitted case. The chrome plating on the bore gage prevents rust, and the insulated handle provides a no-slip grip.
