The DEWALT FLEXDRIVE cordless screwdriver (DWHT66719) is built for assembly work where a full-size drill is overkill. Its 4V motor delivers up to 44 in-lbs (5Nm) of powered torque and spins at 360 RPM, while the manual finishing mode lets you torque down to 124 in-lbs (14Nm) by hand for the last quarter turn. The 2Ah integral battery drives up to 680 machine screws per charge and recharges over USB-C in about 60 minutes, so the screwdriver lives in a tool pouch instead of on a charging dock. The FLEXDRIVE 360-degree collar replaces forward/reverse buttons with a slide-to-drive motion you can…

SpecPicks Verdict

SpecPicks scored DEWALT Cordless Screwdriver, 4V USB Rechargeable Electric… using a rating × review-volume × price-fit model applied to our editorial and benchmark analysis across the tools & maintenance category. Compare with similarly-priced alternatives in the tools & maintenance category before committing. Judge it on the specification table and the price rather than on sentiment: check the figures that decide your use case, then put it side-by-side with two or three close alternatives in the Compare tool before clicking through.

Common buyer scenarios for tools & maintenance: PC towers accumulate significant dust in 3–6 months, so cleaning frequency drives cordless vs. canned-air tradeoff decisions. Match the device's RPM or CFM rating to your case size, and confirm battery runtime covers a full tower cleaning before ordering.

Frequently Asked Questions

How many screws can the DEWALT DWHT66719 drive on one charge?

DEWALT rates the 2Ah integral battery at up to 680 screws per charge, measured with 1/2-inch #6 machine screws at clutch level 2. Heavier fasteners and denser material will reduce that figure.

Does it charge with a standard USB-C cable?

Yes. The screwdriver is USB-rechargeable and works with USB-C chargers and connectors, and a USB charging cable is included. A full recharge takes about 60 minutes, and an LED indicator shows state of charge.

Is 44 in-lbs of torque enough for furniture assembly and cabinet work?

Yes for typical assembly screws. The tool delivers up to 44 in-lbs (5Nm) powered, then lets you finish manually up to 124 in-lbs (14Nm). For lag bolts or large structural fasteners, use a full-size drill/driver instead.

What bits come with it and can I use my own?

Twelve 2-inch bits are included. The quick-load collet accepts standard bits and is designed to keep them secure during use, so you can swap in your own 1/4-inch hex shank bits.

What warranty does DEWALT offer on this screwdriver?

It carries a 3 Year Limited Warranty. Check the product listing for current terms, registration requirements, and coverage details in your region.
