Using a screw remover drill bit allows you to extract stripped or broken screws that standard screwdrivers or drill bits can't grip. The process typically involves preparing the screw head and then using the remover bit to turn and pull the screw out.
Understanding Screw Remover Bits
Screw remover kits usually contain multiple bits designed for different screw sizes. Many modern screw removers are double-ended: one end acts as a drill bit to create a pilot hole in the center of the damaged screw head, and the other end is a tapered, reverse-threaded extractor designed to grip the inside of that hole and turn the screw counterclockwise for removal.
Steps for Using a Screw Remover Drill Bit
While specific steps might vary slightly depending on the type of screw remover kit you have, the general extraction process is key. Based on common usage and the provided reference, here's how the extraction phase works:
- Select the Correct Bit: Choose a screw remover bit size appropriate for the stripped screw you are trying to remove.
- Prepare the Screw (If Necessary): Some screw removers require you to first drill a small pilot hole into the center of the stripped screw head using the drill end of the bit. Follow your kit's instructions for this preparatory step.
- Insert the Extractor Bit: Flip the bit (if double-ended) or switch to the extraction bit. Insert the extractor end into the prepared hole or firmly against the stripped screw head.
- Engage and Turn Counterclockwise: Using your drill or driver set to a slow speed and reverse (counterclockwise) direction, apply steady, firm, and consistent pressure to the back of the screw remover bit while you turn.
- As highlighted in the reference: "You should feel the bit engaged the screw head and then begin to turn it counterclockwise."
- The extractor's reverse threads will bite into the screw metal.
- Maintain Pressure and Extract: Continue turning the bit counterclockwise and applying pressure.
- The reference notes: "Up. And out keep applying pressure to the screw while it turns."
- As the bit turns and grips, it will loosen the stripped screw, allowing it to back out of the material.
- Remove the Screw: Once the screw is loose enough, you can often remove it by hand or continue using the bit until it's completely extracted.
Key Tips for Success
- Use Slow Speed: Run your drill or driver at a slow speed. High speeds can overheat the bit or strip it further.
- Apply Steady Pressure: Consistent, firm pressure helps the bit bite into the screw head without slipping.
- Ensure Reverse Direction: Always use the counterclockwise (reverse) setting on your drill or driver for extraction.
- Start Small: If unsure about the size, start with a smaller bit and move up if needed.
- Safety First: Wear safety glasses when using power tools.
By following these steps, particularly focusing on engaging the bit, turning counterclockwise, and applying consistent pressure as described, you can effectively use a screw remover drill bit to tackle frustrating stripped screws.
