Fourth of July weekend brings many traditions in the U.S., but my favorite is using the extra time to tackle DIY home improvement projects I’ve been putting off. There are often great sales on power tools and home improvement supplies, with retailers banking on the holiday to draw in DIY enthusiasts who have hosting and entertaining top of mind. It's one of the best times to look for deals on quality tools, and this year, the Fourth of July sale at Home Depot includes some big discounts on cordless power tools and batteries, up to 55% off.

If you’re just starting your DIY tool set or looking to upgrade old or damaged tools, investing in a combo set can save you money when you're just starting out. Choose a tool set with a wide variety of tools compatible with its batteries; that way, you can continue building your set without needing to buy multiple battery systems and chargers.

One of the best deals on quality cordless tools from Home Depot is the DeWalt 20-volt, 6-tool combo set on sale for $499, 44% off its regular price. It comes with a drill, an impact driver, an angle grinder, a sawzall, a circular saw, an oscillating multitool, a 5-amp-hour battery, a 2-amp-hour battery, and a charger. This is a pretty comprehensive starter set that will allow you to tackle basic DIY projects like hanging shelves, but also allows you to do some woodworking and repair work, like replacing fence boards or decking.

A DeWalt 20-volt, 6-tool combo set and rolling case is on sale for $549, 39% off its usual price. This set is a little different than the previous one: it comes with the drill, impact driver, angle grinder, and circular saw, but it has an orbital sander instead of a sawzall. It comes with a 2-amp-hour battery and a 5-amp-hour battery, a charger, and a hard-sided rolling case. The case is a good option if you need to take your tools outside your home workshop, as transporting a full tool set can be cumbersome without the right equipment.

Last but certainly not least, the Milwaukee 18-volt, 6-tool combo set is on sale for $449, 55% off its typical price. This set comes with a drill, an impact driver, an angle grinder, a circular saw, an oscillating multitool, a work light, two 4-amp-hour batteries, a charger, and a tool bag. This is a good set for most DIY home improvement projects, allowing you to handle basic and intermediate repairs as well as some woodworking.

Power drills and drivers are also on sale, up to 45% off

Drills and drivers are basic tools you’ll need for DIY home maintenance, useful for anything from hanging a picture to replacing door hardware. This Ryobi 18-volt drill and driver starter set is on sale for $99, 34% off its regular price. This is an excellent beginner set, including the batteries and charger you need to use it right out of the box. It comes with a drill, an impact driver, two 2-amp-hour batteries, a charger, and an insulated case.

The DeWalt compact 20-volt cordless impact driver is also on sale for $99, 45% off its usual price. This is a good addition to a DeWalt drill set, or on its own, for tackling basic DIY projects. It comes with a 2-amp-hour battery and a charger, so you can use it right out of the box.

Batteries are often the most expensive part of a cordless tool set, and they're sometimes the first thing to wear out because even the best-quality batteries tend to lose their ability to hold a charge over time. A good deal on batteries for your tool set will set you up for success, and this set of two DeWalt 20-volt, 5-amp-hour batteries is on sale for $149, 40% off its typical price. This is a battery-only deal, so you’ll need a DeWalt 20-volt charger to use them. These are a good choice if you already have a DeWalt tool set or are buying DeWalt 20-volt tools and want extra batteries.

And the Ryobi 18-volt, 3-battery set is on sale for $179, and it comes with a free tool as well. To get the free tool, click on the “shop this deal” on the menu to the right, then choose what you want from the menu. The final sale price will show up in your cart. The biggest discount on this deal is to add the two-pack of 18-volt batteries from the free tool menu, which gets you four 4-amp-hour batteries, one 2-amp-hour battery, and a charger for $179, 70% off its regular price. This is a good deal if you want to add to your Ryobi tool collection and need extra batteries, or if you use an inverter in your emergency kit, because it lets you keep multiple batteries charged in advance.
