Best Drill for Building a Deck? Plus My Deck Build Story

Hey all, finally starting my deck project next weekend. I'll be using composite decking (Trex) and need a good drill/driver for the job. I have a cheap corded drill but it's dying. Should I go with a hammer drill or is a regular drill fine? Also, what about a separate impact driver? I've seen advice to get both. Any specific models you veterans recommend? Budget is flexible but want to avoid unnecessary stuff.

Welcome to the never-ending deck build! For composite decking, you don't need a hammer drill—that's for masonry. A regular cordless drill will do, but I'd *highly* recommend a combo kit with a drill and impact driver. The impact driver will save your wrist and speed up screw driving like you wouldn't believe. For a solid budget pick, look at the DeWalt atomic series or the Milwaukee M12/M18. I've used the DeWalt 12V Max for years on decks—light and plenty of torque. Don't forget to pre-drill holes for the composite to avoid stress cracks, and use special composite screws that come with a drill bit. Also, check that your driver has a clutch for setting screws without stripping.

Absolutely agree with SocketSarah. And since you're doing a deck, you'll also need to cut the deck boards. An oscillating multi-tool is great for flush cuts, but you didn't ask. For the drill, I'm a fan of the Bosch 12V (for the compact line) or 18V (everyday drilling). I've done restorations on old timber decks, and sometimes you hit hardened screws from previous owners—a brushless drill with a hammer function is nice to have in that case, just to brute-force through. But for new construction, regular is fine. Get two batteries if you go cordless—nothing worse than waiting for a charge mid-project. And never cheap out on bits! Get a set of impact-rated hex bits, they last longer.

DeckBuilderDave, if you're going with Trex, the fasteners are usually driven with a special tool? Some composite brands use a hidden fastener system. Check that first. But if you're face-screwing, then yes, as others said, a drill/driver combo is the way. I've been using a Makita 18V LXT set for my last couple decks—the drill's got a nice all-metal chuck and the impact has two speeds. I also like having a right-angle attachment for tight spots near the joists. One thing I do differently: I set my driver on a lower speed to avoid sinking screws too deep, which can dimple the composite. And use a countersink bit if you can. Last tip: buy an extra battery pack and keep one on the charger while you use the other. You'll thank me later.

Thanks all! I guess I'll grab a combo kit then. I think I'll go with the Milwaukee M18 since I have a friend who has some, but I'll check out the others too. I'll definitely pre-drill and practice on a scrap piece first. Also, I'll get some extra batteries. Appreciate the tips!
