## Long description

Adapter Makita 134873-0 converts a 1/2" 4KT tool holder to a 1/4" 6K hex bit connection for impact drivers. Designed for use with Makita impact tools and other compatible cordless or corded impact drivers, the reducing socket provides a secure mechanical interface that allows 1/4" hex bits to be used in tools with a 1/2" 4-notch receptacle. The adapter is intended for heavy-duty fastening tasks where quick bit changes and reliable retention are required.
Advantages
The adapter offers strong bit retention and stable rotation transfer from the larger 4KT receptacle to the 1/4" hex bit, reducing slippage under high torque. Its compact construction enables access in confined spaces while maintaining secure coupling. The design supports fast bit changes and is compatible with standard 1/4" hex impact bits, allowing greater flexibility on the jobsite without needing additional tool heads.
Suitable for
Converting 1/2" 4-notch drive tools to accept 1/4" hex impact bits
Use with cordless and corded impact drivers for fastening and removal tasks
Tight or confined-workspace fastening where a compact adapter is required
General maintenance, assembly, and construction fastening applications
Key specifications
Input connection: 1/2" 4-notch (4KT) receptacle
Output connection: 1/4" 6K (hex) bit holder
Intended tool type: impact drivers and impact wrenches with 1/2" 4-notch socket
Material and finish: durable metal construction suitable for impact use
Size: compact reducing adapter for improved access in restricted areas
How to use
Insert the adapter into the tool's 1/2" 4-notch receptacle until it seats securely and the retaining mechanism engages. Insert a standard 1/4" hex impact bit into the adapter’s bit holder until it locks. Operate the impact driver at appropriate torque settings and use controlled bursts to avoid over-torquing fasteners. To remove the bit or adapter, depress the tool’s release mechanism (if applicable) and pull the adapter or bit clear of the socket.
Usage recommendations
Use impact-rated 1/4" hex bits with this adapter to ensure safe and reliable performance. Inspect the adapter and bits periodically for wear, deformation, or damage and replace any components showing significant wear. Match the tool’s torque settings to the fastener and material, and avoid prolonged no-load impact operation to reduce stress on the adapter.
