The Proxxon adapter for screwdriver bits 1/4" to 1/4" (PR23778) is a compact connector that enables secure coupling of standard 1/4" hex bits and compatible bit holders. It is intended to allow straightforward interchange between tools and accessories that use the common 1/4" hex interface, improving flexibility when working with screwdrivers, impact drivers, and manual bit holders in workshop and repair environments.

Advantages

This adapter provides a precise fit for 1/4" hex bits and accessories, reducing play and improving torque transfer between the bit and the driver. Its compact design preserves access in confined spaces and makes bit changes quick and uncomplicated. The adapter is made to meet common workshop durability expectations and supports a wide range of standard bits and holders without requiring tool modification.

Suitable for

• Joining standard 1/4" hex bits to compatible bit holders
• Extending compatibility between screwdrivers and bit-based accessories
• Use in light repair, maintenance, and assembly tasks
• Working in confined or hard-to-reach locations where a short adapter is needed

Key specifications

• Interface: 1/4" hex to 1/4" hex
• Function: bit-to-bit/bit-to-holder adapter for hand and powered drivers
• Form factor: compact, short-length adapter for improved access
• Compatibility: fits standard 1/4" hex bits and bit holders commonly used in workshops

How to use

Insert the 1/4" hex end of the bit into the adapter until it seats securely, then connect the adapter to the driver or bit holder by pushing the mating 1/4" hex end into the tool's chuck or holder. Ensure the bit is fully seated and check for any axial play before applying torque. To remove, withdraw the adapter from the tool and pull the bit from the adapter. Use with compatible bits and holders only and inspect the adapter for wear before each use.

Usage recommendations

Use this adapter with bits and tools that match the 1/4" hex standard. Avoid exceeding the torque limits recommended for your tool or bit type, and replace the adapter if you notice excessive wear, deformation, or loss of secure fit.
