DEWALT DCF787 Impact Driver: What Reviewers Say About the Budget Brushless Kit

Impact drivers are the tool that turns assembly-and-decking jobs from a forearm workout into a trigger pull, and DEWALT’s lineup runs from budget to full pro. The DCF787 sits at the value end: a brushless 20V MAX driver that the big tool outlets mostly skip in favor of its flashier siblings, but that a cluster of hands-on reviewers, including one three-year ownership test, keep recommending to DIYers for the same reason: it does the job and costs little.

As of July 23, 2026, the DCF787D1 kit (tool, 2Ah battery and charger) is listed at $99 on Amazon, 45% off its $179 list price. A brushless name-brand impact driver kit at double digits is the promo-kit pricing ToolGuyd notes this model was practically built for.

The short version

The DCF787 delivers 1500 in-lbs of torque at up to 2800 RPM and 3200 impacts per minute through a 1/4 inch hex chuck you can load one-handed. The brushless motor is the quiet upgrade over the older brushed budget models: more runtime per charge, less heat, less maintenance. At about 2.1 pounds bare it is light enough for overhead work and cabinet interiors, and the LED helps in exactly those spots.

What it does not have is a speed selector. Where DEWALT’s DCF850 and DCF860 offer multiple modes, the DCF787 gives you a variable trigger and your own judgment. The reviewers agree on what that means: fine for decking screws, furniture, fencing and general renovation work, less ideal for delicate small fasteners at full squeeze or repeated heavy driving into hard material.

Who this is for

The consensus profile is homeowners, DIYers and hobbyists, especially anyone already on DEWALT’s 20V MAX battery platform, since the kit battery works across the whole ecosystem. Tools Territory’s three-year verdict is the strongest signal here: drops, jobsite abuse and years of use without a failure, which is the thing you cannot read off a spec sheet.

The honest caveats: pros driving big lag bolts all day want the 1700 plus in-lbs multi-speed models, there is no belt clip, and if you have never used a single-speed impact, expect a short learning curve on trigger control. None of the cited reviewers considered those dealbreakers at this price; all of them flagged them.

The deal math

At the $179 list price the DCF787D1 competes against DEWALT’s own ATOMIC DCF809 kits and loses on paper. At $99 the comparison changes: you are paying roughly bare-tool money and getting a battery and charger with it, which for anyone starting a 20V MAX collection is the cheapest legitimate entry ticket. If the card below still shows the discount live, that is the whole pitch.
