Package Contents
- 1x VESSEL WBJ100 6.35mm Pivoting Extension Bit Holder
Setup
- Insert the Bit: Push the collar of the bit holder forward, insert your desired 6.35mm (1/4 inch) hex bit into the holder, and release the collar to lock the bit securely in place.
- Attach to Power Tool: Insert the 6.35mm hex shank of the WBJ100 bit holder into the chuck of your power screwdriver or drill. Ensure it is firmly secured.
The bit holder features a mechanism to switch between fixed and pivoting modes:
- Fixed Mode: Push the upper part of the bit holder down towards the main body to lock it in a straight, rigid position.
- Pivoting Mode: Pull the upper part of the bit holder away from the main body to unlock the pivot, allowing for up to 15 degrees of angular movement.


Operating Instructions
- Standard Operation (Fixed Mode): For general driving tasks, ensure the bit holder is in the fixed (straight) position. This provides maximum stability and direct torque transfer.
- Corner Work (Pivoting Mode): When working in tight corners or at an angle, pull the upper part of the bit holder to engage the pivoting mechanism. This allows the bit to angle up to 15 degrees, providing flexibility to reach fasteners that are otherwise inaccessible.
- Applying Pressure: When using the pivoting function, apply steady, even pressure to the power tool to prevent the bit from slipping or camming out of the fastener head.



Maintenance
- Cleaning: After each use, wipe down the bit holder with a clean, dry cloth to remove any dust, debris, or moisture.
- Lubrication: Periodically apply a small amount of light machine oil to the pivoting joint and the bit retention mechanism to ensure smooth operation.
- Storage: Store the bit holder in a tool box or a designated dry area to prevent rust and damage.
- Inspection: Regularly check for signs of wear, such as excessive play in the pivot or difficulty in retaining bits. Replace if significant wear is observed.
Troubleshooting
- Bit not holding securely: Ensure the bit is fully inserted and the collar has snapped back into place. Clean the internal mechanism of any debris. If the issue persists, the retention mechanism may be worn and require replacement.
- Pivoting mechanism stiff or not engaging: Apply a small amount of lubricant to the pivot joint. Check for any obstructions or debris.
- Excessive wobble during use: Ensure the bit holder is securely fastened in the power tool's chuck. Verify that the bit itself is not bent or damaged. If the wobble originates from the bit holder's pivot, it may indicate wear.
User Tips
- For optimal performance and to prevent stripping screw heads, always match the correct bit type and size to the fastener.
- When using the pivoting function, start at a lower speed on your power tool until you get a feel for the angle and control.
- Consider using magnetic bits with the holder for added convenience, especially when working in tight spaces where dropping screws is a concern.
