Overview
With 1,000 units sold per month, the DEWALT DCD799B is the single most purchased drill in this batch. Its 4.7-star rating from 628 verified reviews confirms that sales volume reflects genuine satisfaction, not just marketing.
At 2.53 pounds, it is one of the lighter 20V cordless drills available. The body measures 7 inches long by 2 inches wide by 8 inches tall -- a compact form that handles overhead work and tight spaces without arm fatigue. The 1650 RPM and 4-amp draw make it capable for wood, composites, and light metal.
At $79.99, it competes directly against 18V rivals while offering the higher voltage of DEWALT's 20V MAX platform. For buyers without existing DEWALT batteries, confirming battery inclusion is essential before ordering.
