Super Low Profile Angled Ratcheting Screwdriver + Bits - ENGINEER - DR-55

The DR-55 uses standard 6.35mm (1/4 inch) hex shank bits. It comes with #1, #2 (x2), #3 Phillips and a 6mm flathead bit.

Yes, you can use any standard 6.35mm (1/4 inch) hex shank bits. Ensure they are securely seated in the magnetic holder.

There is a small slider switch on the screwdriver body. Slide it to the desired position: typically forward for tightening, reverse for loosening, and a middle position to lock the rotation.

The included manual is primarily in Japanese. Basic operational instructions can be inferred from the diagrams, or online resources may offer translations or explanations.

The total length is 111mm, and the tip width is 22mm.

Due to its compact and low-profile design, it is best suited for moderate torque applications. It may not provide sufficient leverage for very tight or seized screws.

The ENGINEER DR-55 is manufactured in Japan and shipped directly from Japan.

Apply a small amount of light machine oil or electrical contact cleaner to the mechanism and work the switch back and forth. Ensure no debris is lodged in the gears. If the problem persists, the internal mechanism may require professional attention.

Check if the bit is fully inserted into the magnetic holder. Ensure the bit shank is clean and undamaged. If the magnetic hold feels weak, it may be a sign of wear and the bit may need replacement or the tool may need servicing.

This is a limitation of the low-profile design. For heavily seized screws, consider using a larger screwdriver with more leverage first, or apply a penetrating lubricant and allow it to soak before attempting removal with the DR-55.

The switch typically has three positions: Forward (arrow pointing in the direction of tightening), Reverse (arrow pointing in the direction of loosening), and Lock (no arrow, or a neutral position). Consult diagrams if available, or experiment carefully to determine the correct orientation for your task.
