JBM-11964 Impact Adapter 3/4" Female To 1/2" Male

This adapter by JBM allows you to convert a ¾″ drive tool socket to fit a ½″ drive tool, or vice-versa depending on your setup. It is designed for use with impact tools (air or electric), offering a robust solution for professional workshops or mobile service vans requiring flexible socket configurations. The adapter features a ball-bearing socket retention system to ensure secure and safe fitment during high-torque applications. 

Key Features & Technical Specifications

• Interface: ¾″ female (input) to ½″ male (output) square drive. 

• Material: Chrome-molybdenum (Cr-Mo) impact-rated steel, designed for durability under high torque. 

• Maximum rated torque: 580 Nm. 

• Input profile: 20 mm (approx. ¾″). Output profile: 12.5 mm (½″) square drive. 

• Designed for use with impact guns as well as manual tool use. 

• Retention: Internal ball bearing lock to hold the socket securely under vibration. 

Applications & Use-Cases

• When a technician has a ¾″ drive impact gun but needs to use a ½″ drive socket set (or the reverse), this adapter allows immediate compatibility without needing full socket set change-over.

• Ideal for heavy-duty workshops servicing trucks, vans or larger equipment where ¾″ tools are standard but smaller ½″ sockets are occasionally required.

• Suitable for mobile service vans where tool space is at a premium and one tool/drive size coverage is desired with flexibility.

• Useful in mixed-use environments (e.g., tyre change, suspension, heavy vehicles, general automotive) where flexibility of drive sizes improves efficiency.

Benefits

• Cost-effective flexibility: Instead of maintaining two full socket and drive tool systems (½″ and ¾″), this adapter allows one system to serve both, reducing inventory and cost.

• Trade-grade durability: Built for impact use with a high torque rating and impact-rated material ensures it meets professional workshop demands.

• Reduced downtime: Quick adaptation between drive sizes means less tool changing and less time lost switching systems.

• Secure performance: The ball-bearing lock ensures the socket stays engaged during heavy use, improving safety and control.
