A mechanic and their tools are inseparable, but it’s almost impossible to have a complete toolset. As the auto world keeps on advancing, so do the tools. The wrench that was the best two years ago may no longer be around in five years.
That's why it’s important to buy the best mechanic tools--the ones that will stand the test of time. We’ve done the research for you, and found the best mechanic tools in different categories to help you pick the best one for your needs. These are the car repair tools mechanics have revealed they can’t live without.
An impact wrench is a power tool that delivers powerful torque output with little exertion. It packs energy in a revolving mass and quickly delivers it to the output shaft. It usually features a 1/2″ socket attachment. An impact wrench can quickly remove very tight bolts and nuts in areas that are prone to rust, like calliper bolts and ball joints.
Air-driven wrenches were once very popular and are still used by many pit crews in motorsports. However, since Lithium-ion batteries were introduced, many mechanics have switched camps and bought cordless impact wrenches. These are perfect for those who don't want to use an air compressor.
Every mechanic needs a selection of high-quality torque wrenches that vary in size. Make sure you get a certificate of calibration when buying the torque wrenches. It proves that they have been tested for accuracy and have attained the highest possible levels of measurement quality.
Get a torque wrench set with 1/4″ pieces for smaller bolts (around 0-30nm) and 1/2″ pieces for bigger bolts (like wheel bolts). The tool allows you to tighten lug nuts without spoiling the rim. It is critical when you’re working with light metals like aluminum that dent and scratch easily. A torque wrench can also be used to set bearings, bolt pulleys, and close the mating surface between the crush plate or gasket.
Digital Vernier Caliper
Mechanics use vernier calipers to measure the outside dimensions, inside dimensions, and depths of small parts of a vehicle.The tool is designed in such a way that its upper jaws measure the inner dimensions, like the diameter of a piece of metal. A digital vernier caliper comes with an LCD display that shows the measurement reading as a number. It doesn’t use a rack and pinion like a dial caliper but a linear encoder that’s far more accurate.
The best thing about a digital calliper is that you can easily switch between centimetres and inches. You can zeroize the display at any point, getting the same measurements as you would with a dial calliper. A vernier caliper is vital for accurate measurements, like determining the tolerance dimensions of bearings. For very precise work, use a high-quality Micrometer instead of a vernier caliper.
The only way you can become better at repairing cars is by streamlining processes, and getting the right mechanic tools is the best way to streamline processes.
