If you want to start building a cordless tool set, DeWalt is a good choice because they’re known for making durable tools that have good battery life and are comfortable to use. DeWalt has been making cordless tools since 1994, and their line of 20v batteries can now power over 300 tools. If you already have DeWalt tools and want to expand your set or replace some batteries, getting a deal on some new gear is a plus. Here are some of the best early October Prime Day on DeWalt cordless tools on Amazon.
Best drill and driver combo set
A quality drill and driver set is the foundation of a DIY tool set. These tools allow you to drill holes for screws and bolts and drive screws and nuts. You can use these tools for anything from hanging a picture to fixing a deck.
The DeWalt 20-volt drill and driver set is on sale for $149, 38% off its regular price. The set comes with a drill, an impact driver, two 20-volt 4-amp-hour batteries, a charger, and a tool bag. This is a good set to start a kit with because it comes with everything you need to use it except for drill and driver bits.
An oscillating multitool is a versatile game-changer in your tool set. You can use it for cutting metal, wood, PVC, drywall, plaster, and tile, and it has a sanding attachment that allows you to sand and polish as well.
The DeWalt 20-volt oscillating multitool set is on sale for $157.69, 47% off its usual price. The set comes with an oscillating multitool, a 20-volt, 2-amp-hour battery, a charger, a sanding attachment, some sandpaper, and three starter blades.
I used my oscillating multitool to replace the drain on my sink, and I was able to cut out the plaster around the old drain, trim the edge of the drain pipe, trim the new PVC sink drain, cut a patch for the wall, and sand the patch all with one tool.
Best cordless saws
Saws allow you to cut and shape wood for DIY builds like shelves, decks, and fences. For intermediate DIY projects and repairs, saws are essential tools.
The DeWalt 20-volt 7 ¼-inch cordless miter saw is on sale for $329, 37% off its typical price. This saw comes with a 20-volt MAX battery and a charger. A miter saw can be used for making straight cuts for frmaing or fencing, but it’s also able to cut at an angle for trim and molding.
The DeWalt 20-volt jig saw is on sale for $139.90, 41% off its typical price. This is a tool-only deal, so you’ll need a DeWalt battery and charger to use it. You can use a jigsaw for cutting custom profiles like cutting molding out to go around a switch plate or outlet, or for shaping fence boards to fit along a slope.
Best random orbital sander
A random orbital sander is an essential woodworking tool. It can evenly smooth out a rough surface on wood, and it helps you finish a surface without leaving tool marks.
What do you think so far?
The DeWalt 20-volt random orbital sander is on sale for $95.99, 46% off its regular price. This sander comes with a dust collection bag, but no battery, so you’ll need a DeWalt 20-volt battery and charger to use it. I use my random orbital sander after filling nail holes on my woodworking projects and to prepare surfaces for paint.
Best batteries
Even quality batteries will wear out over time and need to be replaced. You might also choose to buy extra batteries so you can always have a fresh one on the charger, or so you can use more than one tool at once without switching the battery back and forth while you’re working.
A DeWalt 20-volt XR 4-amp-hour battery is on sale for $68.40, 60% off its usual price. You can also get a pair of 4-amp-hour batteries for $132, 51% off their typical price.
