13 best bore micrometers

Bore micrometers, also known as inside micrometers or internal micrometers, are precision measuring instruments used in industrial and scientific applications for the accurate measurement of the inside diameter or bore of cylindrical objects. These devices are commonly used in fields related to gauges, dimensional measurement, test and inspection, and industrial scientific processes. Here are some key points about bore micrometers:

  1. Design and Components: Bore micrometers typically consist of a C-shaped frame with a measuring head at one end and a thimble and spindle assembly at the other end. The measuring head contains anvils that come into contact with the inside surface of the bore being measured.

  2. Measurement Range: Bore micrometers come in various sizes and measurement ranges, allowing them to measure a wide range of bore diameters accurately.

  3. Accuracy: These instruments are known for their high accuracy and precision, often capable of measuring to within a few micrometers (microns) or even tenths of a micrometer.

  4. Usage: Bore micrometers are commonly used in machining, manufacturing, and quality control processes to ensure that machined parts meet specified dimensional tolerances. They are also used in research and development, particularly in fields where precise measurements are critical.

  5. Operation: To use a bore micrometer, the instrument is inserted into the bore, and the spindle is carefully adjusted until it contacts the bore's inner surface. The reading on the micrometer scale or digital display provides the bore's diameter.

  6. Types: There are different types of bore micrometers, including traditional analog micrometers with a scale and vernier, as well as digital bore micrometers with electronic readouts for ease of measurement.

  7. Calibration: Bore micrometers need to be regularly calibrated to maintain their accuracy.Calibration ensures that the instrument provides reliable and traceable measurements.

  8. Applications: Bore micrometers are used in various industries, including automotive, aerospace, engineering, and manufacturing, for tasks such as measuring the internal diameter of engine cylinders, precision bearings, and other cylindrical components.

In summary, bore micrometers are essential tools for accurately measuring the internal diameter of cylindrical objects. They are widely used in industrial and scientific applications where precise dimensional measurements are crucial for ensuring product quality and meeting engineering specifications.

User questions & answers

Question: What is the graduation in Inches? Im confused! What decimel point do the line segments between the dial numbers, 0.00x or 0.000x or 0.000x
Answer: Note : There are 2 empty anvil spots because 1 anvil is already installed in the foot and the largest spot is intentionally left empty.
Question: Is this tool made in USA
Answer: read the details it just depnds on what your using it for i.e. more precise is what i took from the details hope that helps
Question: What is the difference between this item and the one named "Extender Bore Gauge
Answer: The shaft is approximately 7" long. You won't be able to measuere cam bearings from the fron and it will probably be too long to measure them between the webs of the block. I reccomend a standard internal mike or one that is extended. now for the cylinders, this works every bit as good as the big $$$ ones. Hope that helpls.
Question: How long is the shaft? Is that a shaft extension that is included? trying to measure installed cam bearings
Answer: It's a a "dial" bore gage. Calibration is only checking for dial repeatability & damage. It is checked for size with standards at each setup. No previous calibration required.

Product description

The Fowler 54-646-400 X-tender Dial Bore Gauge Set has a measurement range of 1.4 to 6" and gradient spacing is 0.0005"/.001mm. A two-point contact system is used to detect geometry problems such as ovality and taper, and carbide-tipped contact points provide extended wear and improved abrasion resistance. The gauge is self-centering and includes an extension holder. This product has 1 year warranty offered by Fowler High Precision. If you experience any problem contact Fowler directly for warranty claims.

Bore gauges 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 teeth. Bore gauges are typically calibrated with a setting ring and come in two types: simple and direct-measuring. Simple bore gauges are used with a caliper to transfer the hole measurement, while the more complex gauges take the measurement directly, and display it through a vernier, dial, or digital display. Bore gauges have a two- or three-point contact, indicating how many points on the gauge 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 gauges are used for fast, single-handed operation with repeatable results from one operator to another. Bore gauges can also be used in special applications, such as measuring threads, spline pitch diameters, and deep bores.

User questions & answers

Question: Could I measure a v8 engine cylinder bore with this ? & if so how accurate would the readings be
Answer: The picture and the set are correct. The 1.4 and 2.0 are inserted in their respective heads and the other slot is empty because it is an SAE set. The SAE set and metric set use the same case and the metric set has one extra extension and therfore an empty slot in the SAE set. It is a good tool but the case is very cheap.
Question: Can this meassure cam bore
Answer: I have the higher precision electronic version which is similar and have done extensive calibration in a production environment at a major employer years ago. Most bore gauges follow this approach: For the bore range (tip that you are using) you need a "master ring gage" for that range in order to "zero" the instrument. A micrometer generally does not have the precision needed to calibrate it. (You can get by a good ballpark quick and dirty, but you are introducing some serious error). Those gages you can even buy used for about $30 or less sometimes $10 on eBay. This is because when you remove and insert different sized bit you alter the tool and it needs to be calibrated. Another (more pricey approach) is to get a "master setting tool" which allows you to insert blocks. The key is a physical reference such as a ring or block in the precision grade you want instead of another tool (a major no-no). Any precision work you want to do in the future you want to have these references as part of your tool set. Otherwise there is little point to have a precision tool and no reference.
Question: Hi, where can I get replacement spacers? I bought this product a while back and it didn't come with all the spacers
Answer: Not flat. They have a small curvature
Question: Will this be able to measure the bore of a shotgun barrel
Answer: The battery in the receiver(tag) should be alive to response as sound alarm and flashing.

User questions & answers

Question: Do you take off the Guide Device wheels to measure a 2 1/2" bore? They won't allow the contact point to touch side of bore on the smaller sizes
Answer: Fowler would not allow their products to be made badly so even though this is a budget version of their bore gauge it is made really well in China. I have used it a bit and have no complaints. If you want US made, pay the extra $$ but for occasional use this fits the bill.
Question: I have a twin cam Harley Davision, will the acuusize gauge work, as I need to check the run out on the main shaft
Answer: Hi Scott, they are from China with very good quality. Thanks
Question: Do you ship to Peru
Answer: I've used it to measure inner crank bearing diameter on a few engines in order to calculate oil clearance and never had a problem... I dont see how you could do any real damage unless you were extremely careless/rough about it.
Question: Why does the set they sent me have no Accusize branding on it and it is just cut-outs with numbers and tape on it
Answer: This is a mechanical dial indicator and does not use a battery! "Zero" point is easily preset by rotating the face of the indicator as with all mechanical indicators. The numbers change when measuring the bore exactly as it should because the bore size changes.
