DEWALT DWHT66719 4V MAX FLEXDRIVE 14-Piece Cordless Screwdriver Kit

The DEWALT DWHT66719 4V MAX FLEXDRIVE 14-piece cordless screwdriver set delivers precise electronic fastening with 44 in-lbs of motorized torque and 124 in-lbs of manual spindle-lock finishing strength. Engineered with an intuitive 360-degree slide-to-drive collar and a 6-stage adjustable mechanical torque clutch, this compact inline driver operates at 360 RPM to install delicate fasteners without stripping electrical wall plates or circuit components. Outfitted with an integrated 2.0Ah rechargeable lithium-ion battery, a fast 60-minute USB charging port, and a 4-LED shadowless illumination ring, it provides unmatched maneuverability in cramped electrical boxes and equipment cabinets.

Best Used For:

  • Electrical Panel and Outlet Installation: Driving terminal screws and faceplate fasteners precisely without cracking thermoplastic covers or overtightening connections.
  • Electronics and Appliance Repair: Servicing delicate circuit housings and precision equipment using low-torque clutch stages and soft-start speed ramp-up.
  • Cabinet Hardware and Hinge Assembly: Fastening cabinet hinges, drawer glides, and architectural hardware with manual 124 in-lbs final snugging capability.

Key Performance & Safety Features

  • 360-Degree FLEXDRIVE Collar: Intuitive slide-activation collar engages forward and reverse rotation smoothly from any hand orientation without trigger buttons.
  • 6-Stage Clutch Management: Granular torque presets prevent thread cam-out, screw stripping, and workpiece surface marring in delicate materials.
  • Hybrid Motorized & Manual Drive: Delivers 44 in-lbs under 4V battery power while supporting up to 124 in-lbs of manual hand-torquing via spindle lock.
  • High-Endurance 2.0Ah Cell: Built-in internal lithium-ion battery drives up to 680 machine screws per full charge cycle.
  • 4-LED Illumination Ring: Quad forward-facing LEDs provide bright, shadow-free illumination across dimly lit enclosures with auto shut-off.
