  • ACCURATE MEASUREMENTS : The bore gage features a dial indicator graduated in 0.0001 inch and has a measuring depth of 9.5 inches
  • DURABLE CONSTRUCTION: This indicator with a chrome-plated handle and a two-point contact system is used to detect geometry problems such as ovality and taper; carbide-tipped contact points provide extended wear and improved abrasion resistance
  • SELF CENTERIN: The easily adjustable bore gage is self-centering and includes a 2-inch contact extension holder
  • SET INCLUDES: 2 self-centering measuring heads, an extension holder, 15 anvils, 4 spacers and a fitted case
  • CHROME PLATED: This bore gage is chrome plated to prevent rust and features an insulated handle for a no-slip grip


Fowler Dial Bore Gage Set has a measurement range of 1.4 to 6". This product has a 1-year warranty offered by Fowler High Precision. Bore gages measure holes, or bores, in a workpiece. They can measure the interior diameter of a hole at any depth, while internal micrometers can only measure to the depth of their anvils. Bore gages are typically calibrated with a setting ring and come in two types: simple and direct measuring. Simple bore gages are used with a caliper to transfer the hole measurement, while the more complex gages take the measurement directly and display it through a vernier, dial, or digital display. Bore gages have a two- or three-point contact, indicating how many points on the gage head touch the inside of the bore. Two-point contacts are better at measuring ovality, while three-point contacts are used to measure lobing or triangular form error. Pistol-grip bore gages are used for fast, single-handed operation with repeatable results from one operator to another. Fowler, an American company, manufactures premium inspection and measuring instruments like electronic indicators, calipers, bore gages, and micrometers. The company, founded in 1946, is headquartered in Newton, MA.

These tools are not that easy to use but once you learn it's not too hard to make measurements. The precision seems a bit off but nothing more than about 4 10 thousandths.

For what I need, I'm pretty sure I could get away with 0.001" accuracy. Even 0.0005" would be an indulgence. But when I found this Fowler set with 0.0001" accuracy on Amazon Warehouse Deals for another 25% off, I had to go for it.Nicely made -- maybe not Starrett or Mitutoyo level, but also not Starrett or Mitutoyo price! And this is for a shop environment, so, with careful handling this set will last me.Nice, organized case. Typical blow-mold, so, nothing too crazy there. Just keeps all the extensions/anvils organized.Note: as it says in the instructions, there is one "open" extension post slot in this imperial set. Presumably, the blow-molded case is the same between metric and imperial, and metric has one longer post.Made in China, if you care about that sort of thing.

Pros:decent quality.Comes with everything you need.Does go 1.4" to 6" which is a nice rangeCons:Product description is misleading. It has a0.0001" dial, but it is only rated for a gaurranteed accuracy of 0.0005". So this is not a 0.0001" indicator.Threads are shoddy and might need some "pittsburghing" to keep from galling up.Would i buy again? NoFurther: the poor accuracy is manageable due to the 0.0001" dial. You can see where it jumps. Just make sure you zero the gauge the same as you measure and you should be able to hold around 0.0003" as you get a feel for them. But at this price point, you would be better off getting the cheaper brands for around $60-70 right now for similar accuracy. The only argument to be made for this is that the 0.0001" dial makes deviations stand out a bit more, and the range of 1.4-6". Many at lower price point have less range. Whether that is worth double the cost to you, is your call.

Readings would not repeat. They would vary by .0003" to .0004". While that's less then 1/2 a thousandth , you're paying for a gauge to read .0001. Even when zeroing the gauge, and rechecking it was always off. If you need .0001 accuracy, you need to get a better gauge.

Visually appears to be identical construction to the 60-100 dollar made in China units. The gauge is better suited for reading bearing clearance than some of the cheaper units. It reads exactly the same measurements as my cheap one. Zero difference in performance.
