Wera 05073990001 Power Hex Bit Holder 1/4 Hex Drive

Product Description

The WERA 05073990001 is a power hex bit holder designed for use with 1/4 inch hex shank bits in high-torque power tool applications. Built from steel, this bit holder measures 3 inches in overall length and features a 7/16 inch body diameter. A ring magnet is included to keep bits securely seated during fastening operations, reducing drop and loss on the job. It is suited for electricians, HVAC technicians, plumbers, and other trade professionals who rely on impact drivers or drill-drivers for production work. The compact steel construction handles repeated power tool cycling without deforming the hex seat.

This bit holder is intended for use with 1/4 inch hex drive power tools, including cordless impact drivers and drill-drivers commonly found in residential and light commercial trade work. It accepts standard 1/4 inch hex shank insert bits, making it a practical addition to any technician's driver kit for panel work, fastener installation, or equipment assembly tasks where quick bit changes and secure retention are priorities.

Installation Notes

Installation requires no special tools beyond the power tool itself. Ensure the tool is powered off or the battery is removed before inserting or removing the bit holder from the chuck. Verify that insert bits are fully seated and the ring magnet is engaged before beginning fastening operations to prevent bit ejection under load.
