Types of Best Digital Calipers For Woodworking

Best Digital Calipers Woodturning Online 8

In general, the market offers two types of digital calipers: general-purpose analog calipers and specialty calipers. Even though the distinction is so subtle that most users will overlook it, you should be aware of selecting the best option.

General-purpose calipers

Typically, these general-purpose calipers are intended for use in a general workshop and have the same features and specifications as the specialty model. 

They are not certified for accurate measurement, which may result in inaccurate results. Furthermore, these units are made of low-quality materials that degrade quickly in the harsh work environment.

Specialty calipers

This specialty digital caliper model is designed to take specific measurements, such as key slot or pipe thickness measurements. The adjustment will significantly affect accuracy (general purpose) compared to their counterpart.

This accuracy calibration certificate, on the other hand, will make the tool suitable for professional use.  While the general-purpose unit lacks this certification, it is not without merit. 

This electronic digital caliper is typically used in light-duty or household workshop projects where precise measurement is not required. They save much money while providing more accurate results than a vernier or ruler.

As a result, the best digital caliper with certified calibration is recommended for projects requiring high precision.

What to Look For When Choosing The Best Digital Calipers For Woodworking

Best Digital Calipers Woodturning Online 10

Digital calipers are composed of various parts that significantly contribute to their proper operation and design.

Inside/outside jaws’ way of measuring inside and outside diameters, a depth gauge, an LCD that displays the metrics on a digital screen, the primary scale, and imagery that shifts the measuring jaws up and down the scale.

Each of these elements has characteristics that influence how it works. Understanding these elements and how they function can assist shoppers in making the best decision when choosing the right digital calipers for a particular set of needs.


The ability of most digital calipers to take remarkably precise depth measurements is one of their most significant advantages. A best digital caliper can quantify incremental increases as small as 0.01 inch or 0.0005 inches, depending on the tool’s quality and the operator’s skill level (0.0125 mm).

Electronic digital caliper accuracy is influenced by the electrical parts that translate the spacing between the inside and outside jaws. However, certain hardware components can also play a role.

The measuring jaw movement of digital calipers created from polished steel is typically smoother. A large, contoured driving wheel can aid in finer adjustments by providing more grip for the fingers as they slip down the jaws up and down.

A pair of digital calipers’ overall accuracy is determined by a mix of the user’s talent and the individual characteristics of the unit.

Checking the accuracy

You can use gauge blocks to test the accuracy of the digital caliper. In the workshop, gauge blocks are the length standard. These blocks are commonly used to calibrate micrometers, dial indicators, and calipers. 

The workshop grade can be used depending on the block grades. However, you can send your caliper to an ISO 17025-accredited calibration lab for more serious calibration.

Metric system

Some users prefer the Imperial system (inches and feet), whereas others prefer the metric system (centimeters and millimeters). 

Different parts of the world use different measuring systems, but DIYers may come across both. For example, various automakers use parts with varying measurement systems.

Thankfully, almost all digital calipers show measurements in both inches and millimeters.

Typically, a button on the LCD appears to switch between the two measuring systems. Both systems are frequently printed on the main scale.

Depth gauge

Calipers are commonly linked to two sets of evaluating measuring jaws that close and open on the scale’s top portion.

The third tool is a depth gauge, a small rod that stretches and pulls back from the caliper bar’s end. You can use it to calculate the depths of holes, cavities, and other downturns. The depth measurement in a low-quality duo of calipers, as useful as it is, can be extremely fragile. 

If the depth gauge is critical for a specific application, ensure it is durable enough to withstand repeated use. Stainless steel and carbon fiber are usually suitable, whereas plastic or composite materials are not.


Digital calipers are available in stainless steel, fiberglass, and plastic, each with advantages and disadvantages. Stainless steel is the most commonly used material on high-end digital calipers. 

It’s tough, heavy, and impervious to water, dirt, and oil. The most expensive digital calipers are usually made of stainless steel.

Carbon fiber is a lightweight material with a medium level of durability. Its tightly woven carbon polymer fibers are as strong as steel while weighing only a fraction of the weight.

On the other hand, carbon fiber is not as corrosion-resistant as stainless steel and can deteriorate more quickly when exposed to water, dirt, or UV rays. 

Carbon fiber calipers are typically less expensive than stainless steel calipers, with a few exceptions.

Inside and outside jaws

A digital caliper set’s inside, and outside jaws are the most frequently used parts, measuring an object’s inside and outside dimensions. 

They’re on different sides of the calipers’ main scale, with the outside jaws larger than the inside jaws.

With the outside jaws, measure an object’s outside diameter and the inside jaws’ inside radius.

As the thumbwheels turn, the outside and inside jaws, like the depth gauge, move until they finally come into contact with the item.

Most digital calipers should have powerful, durable inside and outside jaws to effectively and accurately measure. Pay close attention to the inside jaws’ construction quality.

IP54 safety certificates

Best Digital Calipers Woodturning Online 12

Several digital calipers are intended for use in undesirable electronic environments, such as device outlets or open air. If this is a recurring pattern, make sure the digital calipers you select can endure these brutal environments, which is where an IP classification comes in.

IP testing is a third-party certification course that verifies digital elements’ environmental resilience.  The first number after “IP” represents the product’s resistance to solids, and the second number represents the software’s level of moisture resistance. 

The industry standard for an electronic digital caliper is IP54. The “5” indicates that it can withstand mud, whereas the “4” indicates that it can withstand water splashes from all directions. 

If your digital caliper is subjected to harsh conditions, particularly in outdoor environments, look for an IP54 safety certificate.

Water and dust protection

The digital caliper’s reading can be misleading if water, dust, or other small particles enter the electronic circuit board. 

Water and dust can enter the electronic system and cause damage to the LCD screen, internal electronic circuit, battery, and other components. 

Make sure a digital caliper has an IP rating to ensure it is resistant to water and dust.

Look for at least an IP54 rating. This means it passed the water and dust tests with flying colors. 

The number 5 indicates that dust can still enter, but only in small amounts and that no damage is done. While the number 4 indicates that the system is safe even after being splashed with water for 10 minutes.

When considering it, you should be aware of the company that issues the IP rating. Mitutoyo, for example, tests its products with the TUV company. \You could contact the digital caliper manufacturer and inquire about the testing company they use.

How to Use The Digital Calipers For Woodworking

Also, you must always calibrate your digital electronic caliper and use it, especially if they have been inactive for a long time.

Wipe the digital calipers clean, unlock the locking screw from the top, and close the sliding jaw with the fixed (left) jaw using a small piece of paper between the jaws. 

Pull the paper with the jaws closed to clean any remaining dust or debris from the measuring modes.

Put the calipers in this closed position against a light source; no light should be coming between the lower jaws. Through the upper jaws, a small amount of light must be visible.

Press the zero button while keeping the jaws together. Then, slide the calipers open to a fixed point on the scale and take a reading. Close your jaw and repeat 2 or 3 times more. 

You can also check the calibration of the digital calipers against a standardized measuring rod (down to 0.001 accuracy) or length if you have one.

This can work on a wood lathe or a metal lathe.

Tips on How to Use Digital Calipers

Even if they have the best calipers money could buy, DIYers must know how to use them correctly. Here are some general guidelines.

Make sure to “zero out”/reset the LCD reading before taking any measurements. When the display reads “0,” turn the thumbwheel till the outside or inside jaws make firm contact only with the object.

The outside (lower) jaws are used to read the outside diameter, and the inner (upper) jaws are used to quantify the inside diameter.

The depth gauge calculates the depth of an item, groove, or downturn. Slide the thumbwheel until the depth gauge’s tip bottoms out in the object, ensuring the caliper’s bottom is parallel to the measured object.

  • After taking a measurement, tighten the locking screw to save or transfer it
  • Inspect the jaws and scale regularly for signs of deterioration and tear, such as scuffs or burrs, which could impair the precision of the caliper’s measurements
  • To ensure accurate measurements, calibrate calipers professionally or with a calibration gauge once a year. Calibrate the calipers after purchase if they do not come with a calibration certificate

Frequently Asked Questions

Best Digital Calipers Woodturning Online 14

How to use the digital caliper?

It’s very simple. Some quick-instruction buttons are the most common, such as unit conversion, zero reading at any point, and holding the reading. You can get the reading right away. 

Some models allow you to record multiple readings, which are then stored in a spreadsheet on your tablet, smartphone, or laptop.

In how many sizes are digital calipers available?

Digital calipers are available in a variety of common sizes, such as 6′′, 8′′, 12′′, 24′′, or 40′′, where this measurement represents the caliper’s length as well as the maximum overall thickness of a measuring object. 

This caliper measures larger industrial components and automotive parts on the larger end of the size spectrum.

In contrast, a caliper with a smaller 6′′ is too heavy to use in the woodworking trade.

A 6′′ caliper is the most popular, followed by 8′′ or 12′′ calipers. As a result, these calipers are versatile and can measure various surfaces and bores encountered in any project. 

Most of these calipers are inexpensive (budget-friendly), and digital calipers provide excellent value to the ardent craftsman (irrespective of their skill level).

Why should I use a digital caliper?

It is a precision instrument designed to read measurements ranging from finite to highly accurate. This enables it to be used for everything from woodworking to automotive repair. 

It measures thicknesses and can easily compare them across larger plans.  They are capable of taking extremely precise measurements as small as 0.0005′′. (0.01 mm). 

It is extremely useful when making precise cuts (for example, using a table saw) or determining the diameter of a specific object. It is an excellent choice for reading the thickness of any surface or determining the diameter of a bore. 

These measurements are recorded and recounted so that digital calipers provide accurate measurements of a given object.

Why are digital calipers better than dial calipers?

Digital calipers are easier to read and more accurate than dial calipers because they eliminate all guesswork in reading a given measurement.

On the other hand, the digital ones will provide a concise reading of measuring objects and eliminate the need to squint when looking at undersized dash marks.

This digital caliper also displays measurements close to the decimal, allowing you to read more accurate/precise measurements than a dial-style caliper. For added convenience, a few models display fractional measurements. 

However, selecting a caliper is entirely up to you; however, a digital caliper is the best option for displaying accurate results.

How to check the accuracy of the digital caliper?

Best Digital Calipers Woodturning Online 16

You can compare the reading from your digital caliper to a standard. The standard, in this case, is a set of gauge blocks. 

When choosing gauge blocks, be cautious; you must know the appropriate grade for your needs. It would be best if you did not use hobby gauge blocks for manufacturing purposes. 

When the caliper is used for specific lengths, you can buy some blocks only or individually (not in a set).


You must be aware of the types of vernier calipers you require. Each has distinct advantages and disadvantages. You must understand why you require a digital caliper. 

It is important to remember that a digital caliper requires a battery life to provide power to operate. You can’t use it if the battery life runs out.

Choosing the best digital caliper is difficult. Many digital calipers on the market offer excellent features and high quality at an affordable price. 

However, a final decision must be made to select the best one. The best ones should be high-quality, useful, accurate, repeatable, and long-lasting buttons.

Furthermore, the best one should meet your requirements. Water and dust protection can be critical considerations when working in harsh environments. At the same time, data transfer is useful for collecting data quickly.
