What Customers Are Saying
The tool is praised for its exceptional performance, power, and user-friendly features. The brushless motor and POWER DETECT™ technology provide impressive versatility, allowing the tool to handle a wide range of drilling and driving tasks, including challenging materials. Customers highlight the tool's solid, robust construction and ergonomic design, which reduces fatigue during extended use. However, a small number of users have reported issues with the tool's longevity, such as gearbox failures, leading some to consider alternative brands.

I purchased the exact same item shortly before this one. I returned it (as I am with this one) as soon as I received it, because it had the exact same problem of the DCD998 Hammer Drill having Hammer Drill Vibration for ALL settings. (For this type of Hammer Drill): I am used to Hammer Drill Vibration only on the Hammer Drill Setting. I am used to just drilling without Hammer Drill Vibration for all the other settings. I tested a DCD1007 Hammer Drill (that for me is basically a slightly smaller...

Extremely Disappointed – Gearbox Completely Failed
I bought this DeWalt 20V brushless drill less than a year ago, expecting the high quality the brand is known for. Unfortunately, it completely broke down — the internal gears shattered into pieces (see attached photos). I’ve always trusted DeWalt, but this experience was honestly disappointing and frustrating. I used the tool normally and didn’t expect a drill like this to fall apart so easily. The gearbox failure makes it unusable, and now I have to look for a replacement. I feel let down by t...

Recommended based on light duty use
I was excited to get this inflator, it checked a lot of boxes such as ability to use it with a cigarette lighter or A/C power. It has Automatic shut off when set PSI is reached and it is portable. Being a DeWalt I fully expected it to be sturdy and robust. I returned it because while it did most of those things it just didn't impress. The build quality is not up to DeWalt standards. If you want the advertised A/C power ability you are forced to spend another $50 for an adapter that's not in...

best ever
I bought the DCD998B today. Charged it and tried it out. I needed to drill 8 holes in stone and concrete. I spent 45 min with a drill to get 1/3 the way through stone on the 1st hole. I finished with this drill and spent 3 min to finish the hole and 7 others. It didn't come with a battery. What I thought was expensive to begin with ($249.95) Lowes had a deal going. If you bought a lith battery (DCBP520C) and charger for $279.95 the drill was free. At first I thought I didn't want to pay that m...
Do not buy
Bought this drill for heavy duty work i was expecting to do. When i began, it was stuck in hammer drill mode and would not come out. Took back to lowes and exchanged for new one. Second one goes in hammer drill mode on it own and will not run full strength continuously on a fully charged battery. This too is a dud and not indicative of my other dewalt tools, although i have friends who have complained they are having same issues with other dewalt drills of theirs. This drill model is a complet...

Awesome Drill.
I have the DCD996 and now this DCD998W1 power detect hammer drill/driver. While I can not talk negatively in anyway on the 996, but this drill is definitely a refined upgrade to the 996. While they both share a similar look and feel, the 998 looks a little more polished and feels a little more comfortable in your hand. But the biggest difference is in power, side handle, and sound. This drill seems quieter, while being much more powerful. It also seems to have better air flow which seems to keep...
Had mine for 2 years 1 month until the gear box broke. Looks like i'm buying a new one
