Product information

Description

The Power screwdriver DeWALT DCF840NT-XJ is a reliable battery-operated tool designed for various fastening and driving applications. Featuring a powerful motor delivering a maximum torque of 200 N⋅m, this electric screwdriver ensures efficient performance on demanding tasks. Built with a comfortable pistol handle design and operating on an 18 V battery system, it provides high mobility and ease of use without the restriction of cords. The tool comes in a distinct black and yellow finish, representing the standard durability and quality associated with the DeWalt brand.

Advantages

This power screwdriver stands out due to its high torque output of up to 200 N⋅m, making light work of stubborn screws and heavy-duty fastening jobs. The 1/4 inch chuck diameter allows for broad compatibility with a wide range of standard bits and accessories. Adjustable speed settings provide enhanced user control over different materials, ensuring precision during delicate operations. The cordless design powered by an 18 V battery offers maximum freedom of movement on any job site. Additionally, the ergonomic pistol handle reduces user fatigue during extended working periods.

Suitable for

  • Assembly of wooden and metal structures
  • General household repairs and furniture building
  • Professional construction and renovation tasks
  • Automotive maintenance and repair work

When it may not be suitable

This tool may not be suitable for heavy drilling applications into reinforced concrete or solid stone, as it is primarily engineered as a screwdriving and fastening instrument rather than a rotary hammer. It might also be oversized for very delicate electronics repair where miniature precision tools are required.

Key specifications

  • Maximum torque of 200 N⋅m
  • 1/4 inch chuck diameter
  • 18 V battery power source
  • Pistol handle shape
  • Adjustable speed functionality
  • Black and yellow product colour

How to use

To operate the power screwdriver, insert a compatible 18 V battery into the designated slot until it clicks securely into place. Attach the required bit into the 1/4 inch chuck securely. Select the desired operational speed using the adjustable speed trigger based on the material and fastener size. Position the bit firmly onto the screw head, maintain a straight angle, and press the trigger to begin driving. Release the trigger once the fastener is fully seated to prevent over-tightening or stripping.

What to consider before purchase

  • Compatibility with existing 18 V battery platforms from the same manufacturer
  • Requirement for separate battery and charger acquisition if not already owned
  • Intended application scope focusing mainly on driving rather than heavy drilling
Usage recommendations: Always wear appropriate personal protective equipment, including safety glasses, when operating power tools. Store the screwdriver in a dry environment and remove the battery when performing maintenance or changing bits.
