Written by David Rowan / Fact-checked by Eric Devin

Generally, the dial bore gauge allows one to measure devices used for accurate measurement to hole. That means it can measure the internal hole of a cylinder with better speed and accuracy. As we know, it comes with a dial indicator for the reading display in real-time. This tool is used to measure the hole’s diameter. And it is commonly used by engine builders or machinists.

best dial bore gauge

Dial bore gauge is allowed to calculate a boar directly. And a good gauge always provides the desired result. You get accurate measurements most easily and faster. It is the best use of your money.

If you want to purchase a new dial bore gauge, then this article is for you. After a lot of reaching, we made a shortlist of the best dial bore gauge kits. There are seven dial bore gauge tools well described.

Choose one as your needs. If you do not have money issues, you can choose the Mitutoyo dial bore gauge tool as the best choice for you. Otherwise, you can choose any one from our list. All come with good features.

How Many Parts Has the Dial Bore Gauge 

There you know the basic knowledge about the thing that will help to purchase a gauge. But get an evident concept about a bore gauge you know all the parts of. These are significant parts of a dial bore gauge.

  1. Dial Indicator: It helps to read the measurement.  
  2. Adoption Screw: You can change your dial indicator with another dial indicator. Just unscrew this adoption escrow part of untightening it. Then you can replace it easily.
  3. Grip. You can control the bore gauge by the part.
  4. Gauge head: Last part is the gouge head. This part has few sob parts. They are described below.
  • Anvil: This part contacts the bore’s wall. They are divided into two parts: an interchangeable anvil and another moveable anvil. 
  • Centering contact: This part also contacts the bore’s wall, but it also helps the anvil in the correct position.

Difference Between Dial Indicator and Digital Indicator

Nowadays, all dial bore gauges do not come with a dial indicator. Some come with digital indicators. That means we are divided in two ways. 

  1. Dial indicator and
  2. Digital indicator.

Both indicators offer mainly the same features. But also some quiet differences let’s know about those facts.

Dial indicators can transfer the result into another device like a pc, smartphone, or laptop. On the trisection, there is no need for any wire. There you can use Bluetooth in this case. 

A digital indicator provides more advantages than a dial indicator. There are easy setup procedures of zero reading, no need to calculate by the scales and convert inch to mm. 

However, both are good for their place. It is a little expensive. But when time is a matter for you, then you can choose the digital indicator.

How to Choose a Good Dial Bore Gauge? 

You have to have strong knowledge about all its body parts. Our article will help you to choose a good dial bore gauge for you. There is a buying guide in our article. Here we describe what things should be essential to buy this tool. 

Make sure your bore gauge comes with a 0.0001-inch resolution to get an accurate measurement. 

How to Take Accurate Measures With a Bore Gauge?

Machinists use a dial bore gauge to measure the inner diameter of bores. Using this tool can save valuable time. Now we know how to take accurate measures with a bore gauge tool. Read the below-

  • Place your gauge with the micrometer locked in the same diameter.
  • Now rotate its dial unit with the 0 points.
  • Inside your dial, bore gauge into the bore and make sure all avils touch the walls.
  • If the tool is squared, then the same pointer shall be started for reserve and head in the opposite direction. 
  • Record the two-point measurement. Where the bore gauge pointer reverses and removes from the hole.
  • Now remove the bore gauge and add the recorded value from the target numbers. 
  • Example: If your bore gauge was 0 to 2 inches. And the pointer changed direction was 0.007 inches, then 2.007 inches is the final measurement of the hole.

What Should Things Be Considered Buying a Bore Gauge?

Most people think that all dial bore gauges have the same features or parts. Essentially, they all use the same principles. But they are not the same features or performance.

Without any knowledge about a dial bore gauge tool, you don’t choose the best model for you. Because there are various models available in the market, you need to read this part. Here we describe all the essential things that should be considered when looking for a dial bore gauge.

Range of Measurement 

Measurement range is the essential part of a bore gauge tool. According to Wikipedia, “When a dial bore gauge tool is used a ring-gauge then should be accurate within 0.0001 inch”. So, there is a number that can strongly affect the range, like the cross-section. 

Overall, if you are working in a broader area, you have to choose that bore gauge with a decent diameter of 0.7 to 0.6 inches. We found an item on our list, “Fowler X-Tender Electronic Dial Bore Gage kit.”


The second important thing needed to consider is the working efficiency of a dial bore gauge. By this work efficiency, you can know how deep it can reach during working on a bore. When you are working on a long cylinder, then you need a more extended range bore gauge. Otherwise, you can choose any range of products.

According to our list, you can choose the Anytime Tools 0.7 to 6 inch Dial Bore Gauge because it offers a high range and quickly reaches up to 10 inches depth.

Tools Accuracy

When you look for any type of tool, there must be knowledgeable about the tool’s accuracy. Most likely, you used the gauge to measure the bore or filling jobs. That is why there are accuracy matters present a lot. 

So, therefore it is necessary to select a product that comes with enough accuracy. According to our list, the Extender Internal Measure Cylinder Tool Set comes with higher accuracy, which gives your needle response.

Product Durability

Don’t forget to check the product’s durability before purchasing one. We don’t mean that they would be made of lower durability. Now, let’s get to know how to identify the product’s durability. Make sure your gauge has abrasion features. Because this feature ensures that it can handle the damage which will come with the frequent usage

Storage Case

Don’t choose a gauge without a case. Because the case keeps your dial bore gauge all accessories together and your kit should be safe in a case. Some cases come with padding for more safety, and some come without padding.

It must be the case made by which material. ABS is the most durable material which makes the storage cage. When the gauge is not to be used, then the case is helped to stay together and protected. 

Gauge Weight

To efficiently carry them might be lightweight. And also easy to use correctly. Most of the products in the market come, lightweight. But sometimes, it depends on how many accessories you need with the gauge. Or if you need a gauge without any accessories, then it will be so lightweight and simply easier to carry.

Final Talk

The dial bore gauge is one of the handy type devices. If you need an exact measurement of bores, then the accurate dials and the measurements will help you successfully do your job. Here we talk about seven different dials bore gauge products. If you need a dual reading electric indicator, then you choose the Fowler XTender dial bore gauge.

If you want a bore gauge for your various industrial applications, then the Accusize Industrial Tool is suitable for you. Or if you need deep bore measurement, then the Anytime Tools 0.7 to 6 inch Dial Bore Gauge and Extender Internal Measure Cylinder Tool Set will be the right choice for you. So, make your choice as your needle requirement.
