When you are working to accurate tolerances within your workshop or other engineering environment it is important to be able to measure items precisely. With high quality and accurate micrometer tools, you are able to measure items to a fraction of an inch in order to guarantee the best possible fit of whatever you are working on. Modern engines are highly delicate and refined items, and the slightest imperfection in any work that you carry out on them can have long term consequences in terms of the reliability of the unit, as well as causing damage to the structure.

The most common micrometer tools come in the format of a caliper. These items, known as outside calipers are designed in a number of ways; however they always have the same basic format, which is to measure an object on the outside edge. The system works by fitting the object that needs to be measured into the caliper and then tightening the screw tightly against the item. Once the gauge is tight against the object that is being measured, you can read off the dimension from the gauge and know the exact size down to the level of accuracy of the particular micrometer tool that is being used.

Although micrometer tools have been available for many years, they have traditionally used a rotating scale that can be difficult to read and cause problems for people who are not full cognizant with the system. I the last few years, a number of manufacturers have started to produce digital displays on their gauges. These combine the same levels of accuracy that you would expect from a precision tool with the ease of use that comes from a much more user friendly measuring system. When it is important to get the most accurate possible measurement, you also need to be able to understand the readings that they provide; otherwise the purpose of the work is completely undermined.

One of the most common areas that you will need to have a micrometer tool to measure in a workshop is in the maintenance of a braking system. Having an accurately positioned caliper is important for a safe and reliable system. The gauge should be used to measure the gaps between the brake pads and the disc so that the braking power is applied evenly and soundly to provide the best possible stopping power. Accuracy of 1/1000 of a millimetre is possible from a micrometer tool, and this provides you with the ultimate precision when carrying out a job, and ensures that the results that you get from your work are as reliable as possible.

Red Hill Supply offer specialist digital brake rotor and drum gauges for $1,201.33. These are intended to provide mechanics with the ultimate means of repairing and maintaining safety while ensuring the levels of customer service that modern consumers expect. The calipers are easy to use, and thanks to the digital display on the unit, they are also simple to read, allowing you to get a result you can rely on whenever you measure an item with the gauge.

With a micrometer tool, you are paying for the incredible accuracy and precision that the tool offers. Unlike a fairly cheap ruler, which is designed for at a glance measurement, a micrometer is intended to provide the most exact possible measurement so that the user is able to get the results that they want every time. Although you can find cheap micrometer tools available, these are often best avoided unless you are able to use a separate tool to

confirm their accuracy, as when working with close tolerances on important systems such as a brake or piston, a slight error in measurement can cause major long term problems, or even render a system dangerous.

You can get a basic micrometer tool such as the Central Tools CEN3M130 from Red Hill Supply from as little as $34.25. This small and lightweight gauge is accurate to 1/1000mm and can measure up to 1.3” objects making it ideal for measuring the thickness of brake rotors to ensure that they are well maintained and fit for purpose.
