The Types of Brake Clamps: All You Need to Know

By Admin | June 12th, 2025

Do you know what a calliper is? Callipers, also known as brake clamps, are tools that possess two adjustable jaws or legs to measure the dimensions of any object. They’re mechanical engineering devices that hold great importance for metalworking. Apart from metalworking, callipers are also crucial for a wide range of tasks.

Woodworking, gunsmithing, and woodturning are among the most significant. It means there are several categories created to perform specific purposes. Many of us are unaware that some callipers are digital and feature digital displays. In this article, we will discuss the various categories of callipers and their operational procedures. Contact a renowned firm joint caliper supplier in Dubai, UAE, to buy your preferred callipers at a reasonable rate.

How Do Callipers Function?

Callipers are tools that we use generally for measuring objects. These tools are ideal for specific applications that you can’t perform with measuring tools like rulers. Callipers consist of two legs fastened to a central hinge. They allow the callipers to move closer together to reach a specific reading.

For instance, a spring calliper needs another measuring tool, like a ruler, to gauge the distance between the measuring legs. These tools are also known as transfer measuring tools. Other categories, such as dial, digital, and vernier, involve a scale. It means you can read the measurement straight from the display on the tool.

Top 5 Categories of Callipers You Should Know

We all know that callipers are effective and extremely easy to use for achieving precise measurements. Below are the most common categories of callipers you can use for several purposes.

Vernier Calliper

The first notable category of callipers is the vernier calliper. Do you know who invented the vernier calliper? It’s none other than French mathematician Pierre Vernier in the year 1631. These callipers involve dual scales that go through the top and bottom. These callipers show both metric and imperial measurements. Some categories of vernier callipers also feature digital readouts.

Those devices can measure both inside and outside diameters, as well as depth. Vernier callipers can gauge up to 1/10 mm, which is known as the least count. Want to buy high-end vernier callipers for your job? Look no further and contact a reputable thread plug gauge and ring gauge supplier in Dubai, UAE, like Abasco Tools. Being a world-famous tool supplying brand, we also offer top-notch callipers for every purpose.

Electronic or Digital Callipers

The next significant type of callipers is the electronic or digital calliper. These callipers are the latest innovation in technology. Many of us are unaware that electronic callipers contain an inner microprocessor. It gauges the position of the legs and shows the measurement on an electronic display.

Spring Joint Callipers

Have you ever heard about spring joint callipers? This is a prominent type of calliper that involves two legs, an adjusting nut and a spring. You can adjust the space between the two legs of these tools by simply twirling the nuts and screw. This type of calliper doesn’t include any scale. Hence, you can check this type of calliper against a measuring device like a ruler.

There are mainly two types of spring joint callipers. The first category is the inner spring joint calliper, and the next is the outside spring joint calliper. The former category is ideal for measuring the diameter and thickness of objects. On the other hand, the latter can measure distances as well as the diameter of holes.

Dial Callipers

Dial callipers are a type of calliper that includes a dial display with an indicator needle to display the readings. Dial callipers are suitable for measuring inside, outside, depth, and step dimensions.

Odd Leg Callipers

The last and final category of callipers is the odd-leg calliper. When it comes to drawing lines from the edge of a workpiece or object to a specific distance, odd-leg callipers are the most suitable option.
