6 Most Essential Power Tools for DIY Automotive Work


A man who says his car isn’t important is secretly lying. It doesn’t matter what vehicle they have, from rundown Renaults to fancy Ferraris, a car is one of the biggest parts of his life. Which is why he’s willing to spend time and money on keeping his car in tip-top shape.


Not only is letting a professional mechanic do the dirty work for you somewhat emasculating, but it’s downright expensive. Doing tune-up jobs under the hood of your car is a challenge, and it can be impossible if you don’t have the right power tools on hand. These are the most essential power tools that pro mechanics swear by.

1. Impact Wrench

Wrenches are used to tighten and loosen nuts and bolts. However, what happens when you’re dealing with seized nuts and a regular wrench just can’t cut it or you end up bashing you knuckles against adjacent metal pieces? You employ heavy-duty tools like an impact wrench, a handheld electric or pneumatic power tool that delivers a ton of torque for busting even the rustiest, most seized nut imaginable. Pneumatic impact wrenches are more powerful but require an air compressor to operate.

2. Die Grinder

Die grinders are one of the most versatile tools in woodworking, automotive work, and even everyday home repairs. Die grinders are equipped with a die attachment which grinds surfaces and removes a very thin layer of material. The grinding die can be switched for sanding and cutting attachments.

3. Random Orbital Sander

Even though die grinders can be used to sand away thin layers of material, you’d have to spend hours and hours on large surface areas. This is where random orbital sanders come into play. They come with large sanding pads for quick removal of more material, but that’s not all they do. To keep your car’s body as shiny as possible, you can attach a sanding buff onto the orbital sander to apply polish and buff it away. It beats manually buffing your car with a microfiber cloth.

4. MIG Welder

Welders let you join two pieces of metal together. It might not be the most useful tool in all situations, but if you’re interested in doing heavy-duty car repairs, then you’ll definitely need one of these machines in your shop.

5. Needle Scaler

Many parts of a car are prone to rusting if not properly cared for. To get rid of rust easily, you’ll need a needle scaler while sort of looks like Chthulu’s head and face tentacles. The tentacles are actually long needles that lift rust effortlessly. The best needle scalers are pneumatic tools that require the use of an air compressor.

6. Digital Torque Wrench

Over and under tightening bolts can be dangerous. Assembling your car together after tearing away part by part is going to be a lot of trouble if you don’t tighten the nuts and bolts well enough. Doing this requires the use of a digital torque wrench which displays how much torque you’re exerting.
