Fowler 54-646-401-0, Digital Dial Bore Gage Set for 1.4 - 6/35mm-150mm Measuring Range

The Fowler 54-646-401-0 X-Tender-E Electronic Dial Bore Gage Set offers a range of features for precise and reliable measurements. With a measuring range of 1.4 to 6 inches and a resolution of 0.00005 inches or 0.001 millimeters, this electronic bore gage provides accurate readings. The direct-measuring gage includes a minimum hold feature, which locks on the bore size as the gage is rocked within the part to be measured, ensuring consistent and repeatable results.

The electronic indicator on this bore gage can display both inch and metric readings, catering to the diverse needs of users. The two-point contact system is designed to detect geometry problems such as ovality and taper, while the carbide-tipped contact points offer extended wear and improved abrasion resistance, enhancing the durability of the instrument.

Versatility is a key attribute of this bore gage, as it is self-centering and includes a 2-inch contact extension holder, allowing for measurements in various applications. The gage set comes with a storage case, 2 batteries, 15 measuring anvils, 4 spacers, and an instruction manual, making it a comprehensive solution for users.

Bore gages, such as the Fowler 54-646-401-0 X-Tender-E, are essential tools for measuring the interior diameter of holes, where internal micrometers may fall short. These gages can measure at any depth within the bore, unlike internal micrometers, which are limited by the depth of their teeth.

Bore gages can be categorized into two types: simple and direct-measuring. Simple bore gages are used in conjunction with a caliper to transfer the hole measurement, while the more advanced direct-measuring gages, like the Fowler model, take the measurement directly and display it through a vernier, dial, or digital display.

The number of contact points on a bore gage is an important consideration, as it affects the gage's ability to detect specific geometry problems. Two-point contacts are better suited for measuring ovality, while three-point contacts are used to measure lobing or triangular form error.
