GoKawiilThe difference between the professional home builder and the DIYer often comes down to tools. While I would never want to play down the role of skill, having the right tools is often part of building those skills needed to build and repair things yourself. If you don't have a drill, it doesn't matter how skilled you are with a drill because ... you don't have a drill.
The first step to developing any repair skills is to make sure you have the right tools for the job at hand. That doesn't mean you need every tool. This is the trap many budding DIYers fall into—buying every tool around and then hardly using them. I spared myself this trap by living on the road in an RV. I can't own large tools like a table saw or miter saw, but much of what you do with a miter saw you can do with a circular saw and speed square. Much of what you can do with a table saw you can do with a circular saw, a long straight edge, and some clamps.
After years of DIY, fixing up old houses, building out a school bus, restoring several vintage campers and RVs, and countless other small projects, these are the three power tools that I use on almost every project.
A Good Drill
A drill, and some quality drill bits, will likely be your most used power tool. It's essential for almost any common house repair job. A drill can do more than just drill holes. You can mix paint, plaster mud (though that's hard on it), grind rust off metal, or even polish your car. Drills don't require a ton of power and were one of the first tools to be reliably usable with batteries. That's still true today—I change the battery in my drill less than any other tool, despite using it all the time.
Most people will be fine with a 12-volt, 8-amp drill for small jobs around the house. If you want something heavier duty, grab a 10-amp or higher model, usually an 18-volt drill, which will work for drilling into harder substances like thick metal or concrete. (Technically, you might want a masonry or hammer drill for concrete. Don't tell anyone, but I use my regular drill all the time.)

This is the tool that had the most profound “I can't believe I didn't own one sooner” impact on me. Get it? Anyway, yes. You can drive in screws with a drill and some impact bits, but you'll burn out the drill faster and strip more screw heads. An impact driver works like a torque wrench, applying rotational force in short, sharp bursts (impacts) to make the screw turn without destroying the head of the fastener or the motor of the tool.
