SATA GL12917 3/8" Drive Bit Adapter 1/4"

The adapter converts a 3/8" drive to accept 1/4" bits. It is designed to maintain a snug, secure connection to minimize wobble and ensure reliable performance when changing bits.

It’s suitable for a range of tools that use a 3/8" drive, including manual ratchets and compatible power tools, allowing you to work with 1/4" bits across various tasks.

1) Insert the adapter onto your 3/8" drive tool. 2) Insert a 1/4" bit into the adapter. 3) Ensure the fit is snug and square before applying torque. The design supports fast, secure bit changes for efficient workflow.

The adapter is made from high-strength chrome vanadium steel with a corrosion-resistant chrome finish. It’s built to withstand high torque applications while maintaining a secure fit and long service life.

Yes. Always confirm the bit is fully seated and the adapter is securely attached before applying torque. Use eye protection where appropriate and avoid forcing bits or using damaged components to prevent slippage or tool injury.

Great for automotive work, mechanical assemblies, appliance repairs, furniture assembly, and any task where you want to run 1/4" bits from a 3/8" drive system.
