    • Good price and works well, nice to have an extra
Style: Brushless Impact Driver (Tool Only)
I have the brushed version of this driver which is several years old. I don’t use it daily so it’s still in good working condition. But I’d always wanted a 2nd one (used or new) as a backup, or to maybe keep in my car in case of a flat. But I never wanted to pay DeWalt fanboy money. This was a really good deal. I was a bit skeptical how well it would work, but I used it this morning to take the lug nuts off my car to swap from winter to summer tires. It got all 20 of them off with little to no struggle; I didn’t have to resort to using a breaker bar. If you already have DeWalt batteries this is a nice addition to one’s tool set. ... show more

Style: Brushless Impact Driver (Tool Only)
Impact is a great little tool. I guess the name says it all. No battery with this guy, but it’s an add on to my current set of tools from dewalt.

    • Great Driver - wait for a sale!
Style: Brushless Impact Driver (Tool Only)
The DeWalt Impact Driver is a total powerhouse! Used it to tackle two major projects: building a sturdy fence and crafting bookshelves for my wife. This tool is a game-changer, much more powerful than just a regular drill. The sheer torque and precision saved me hours of work. The battery life is impressive, lasting through both projects without needing a recharge. Its compact size makes it easy to handle, even in tight spots. If you're into serious DIY projects, this Impact Driver is a game-winning choice. Wait for a sale - I got mine for around $75. ... show more

    • great for installing hangers for deck joist
Style: Brushless Impact Driver (Tool Only)
I have used an electric drill for years but as I was reviewing how to build a deck everyone suggested using an impact driver. They were not wrong. So much easier for installing the screws. Took me a bit to get used to the ratchet fell as it toques the screw but I got used to it quickly. This is small and makes it easy to get into tight spaces. ... show more

    • Quality DeWalt
Style: Brushless Impact Driver (Tool Only)
This is a heavy duty driver. Great torque, balance and ease of use. You can drive long screws through wood without having to put presure on the tool. Great ergonomic design. Buy DeWalt!
