The overall score is owner satisfaction weighted by how many reviews back it, so a high rating from few reviews counts for less. The bars below show where this model stands against the other power tools and workshop machinery we track in this category on price, popularity and size. Context, not marks against it, and our read of the data, not a lab test.
Overview
The Dewalt DCD798B runs on the 20V MAX battery platform and draws 4 amps in a 3.2-pound body. Its 4.7-star rating from 269 reviews is a strong quality signal, and the $117.80 price positions it above the more popular DCD799B.
The listing does not publish a usable RPM figure, which limits direct speed comparisons. The 3.2-pound weight is close to the DCD799B at 2.53 pounds, so the premium price should be weighed against what specific features or construction differences the DCD798B offers over its sibling.
With 0 units sold in the most recent monthly data, buyer activity is currently low. This may reflect a newer listing or reduced stock availability rather than a quality issue, given the 4.7-star average from existing owners.
