Magnetic Bit Holder with Screw Guide DeWalt DT7702-QZ — 12 mm shank, 120 mm length

DeWalt Magnetic Bit Holder DT7702-QZ is a 120 mm long bit holder with magnetic retention and an integrated screw guide, intended for use with 12 mm shank bits. Designed for compatibility with both cordless and corded drivers, this tool extends reach while holding bits securely and guiding screws for more accurate, single-handed fastening. The holder's length and guide help reduce wobble and improve access in confined or recessed fastening locations.

Advantages

The magnetic tip retains bits and fasteners reliably during operation, reducing dropped screws and speeding up repetitive tasks. The integrated screw guide centers screws on the bit, improving alignment and allowing controlled insertion in tight or awkward positions. Its 120 mm length provides additional reach without sacrificing stability, and compatibility with 12 mm shank bits makes it suitable for common professional and DIY screwdriving applications.

Suitable for

• Assembly work and production line fastening
• Carpentry, joinery and cabinet installation
• Maintenance and repair tasks in confined spaces
• Electrical and plumbing installs where extended reach is needed
• General DIY projects requiring controlled screw placement

Key specifications

• Overall length: 120 mm
• Shank diameter compatible with: 12 mm
• Magnetic bit retention for secure fastening
• Integrated screw guide for centered screw feeding
• Suitable for use with cordless and corded drivers
• Material: hardened steel components for durability

How to use

Insert a compatible 12 mm shank bit into the holder until it seats against the magnetic tip. Place the screw into the integrated guide and position the screw on the workpiece. While applying light forward pressure to keep the screw engaged in the guide, operate the driver at controlled speed to start and drive the screw. For deep or recessed applications, use the full 120 mm length to reach the fastening point while maintaining alignment with the guide.

Usage recommendations

Use appropriate driver torque settings to avoid overdriving screws; select bits that match screw head profiles for best fit. Inspect the magnetic tip and guide periodically for wear or debris and clean as needed to preserve secure bit retention and smooth screw feeding.
