Much Better Than My Bosch 18V
Much Better Than My Bosch 18V I switched from an 18V Bosch hammer drill to this DEWALT 20V MAX, and the difference is substantial. Build quality feels a clear step up—I’ve dropped this one from a ladder several times with zero damage. Power delivery is stronger and more consistent thanks to the brushless motor, while the compact size handles tight spots well. It fits perfectly into my existing DEWALT battery system. The only downside is some fatigue during long overhead sessions due to weight. Solid, durable tool that outperforms my old Bosch in everyday use.

Used but new?
I am sure the drill is great. Much heavier and torque than my one of over 19 years that I love. I needed the upgrade for the hammer drill for framing a couple of medium size rooms into concrete. What annoyed me, I got it for Xmas from the family (I chose it) but it came with no box or manual. Do I really need these things, no, probably not. It does suggest that this was a returned item. Also fine, it appears unused, no blemishes at all, but I paid for a new unit. Might return it, just to make sure I get what I paid for. Really hate when Amazon tries to pawn off returned items as new, without the proper packaging.

So far good product. 01/2026 Update.
It works great! 01/2026 - Update: It will not disengage from hammer-drill mode. I took it apart and the problem is in the chuck side of the drill head. I removed the hammer-nubs and it works fine as an ordinary drill. I recently purchased a DeWalt SDS hammer-drill, so, I’m covered for both uses. If you are an average/semipro user, a DeWalt fits the need for the price. As a pro user I suggest the hi-er-end DeWalt or a Hilti hammer drill.

Rugged, powerful, outstanding drill & battery line.
I'm very late to the Li-ion battery portable tool revolution, and am glad I landed on the DeWalt 20V product line. The drill is vastly superior to my very old Bosch rechargable drill, not even considering the upgrade to hammer function, which is welcome. I appreciate the knurled metal check with its full 1/2 inch capacity and strong grip. This looks to be a drill that will carry me for well over a decade. But hey, Amazon... why are you shipping it loose in a plain brown box, with just paper manual and belt clip? If you're sending a product in the manufacturer's own packaging, make that clear to the buyer. For the record, the drill is brand-new, had no signs of use, and is labeled made in Mexico. I ordered in July 2024, the drill was built in 2023.

Excellent product
A replacement for my previous conventional DeWalt drill (which is still alive, albeit showing signs of its age,12 years later). This version is a hammerdrill. This is a work tool & so far it has performed admirably. Way faster & quite a bit more powerful than its ancestor. I'm holding out on that 5th star until I see how long lived it is (I wouldn't recommend holding your breath). I received the drill within a few days...good service, good price from this provider. Get you one.

It's a part of my handyman bag of tools. Just like Dewalt to make a good product.

La verdad, para los pequeños trabajos que hago es una gran herramienta. Sólo de verlo te enamoras, gran poder, ergonomía, peso, calidad. La luz que tiene es de gran ayuda. Por 2k de precio ¡Inmejorable! Espero que me dure muchos años funcionando bien. Lo recomiendo ampliamente. Ah! Me enviaron una maleta Dewalt de regalo que no incluía en la descripción, gracias. Cabe perfectamente el taladro, el cargador y dos baterías power stack.
