25PC.SCREW EXTRACTOR & DRILL SET 5~14MM

A 25-piece screw extractor and drill set covering sizes from 5mm to 14mm is a comprehensive toolkit designed to remove broken or stripped screws, bolts, studs, or other threaded fasteners from materials such as metal, wood, or plastic. This set typically includes a variety of extractors, matching drill bits, and other accessories needed for extraction tasks. Here’s an overview of what you might find in such a set:

Components of a 25-Piece Screw Extractor & Drill Set (5mm to 14mm):

1. Screw Extractors: The set includes a range of screw extractors, typically designed to fit various screw or bolt diameters from 5mm to 14mm. These extractors have reverse threads that grip the inside of the broken or stripped fastener to facilitate removal.
2. Drill Bits: Matching drill bits are provided to prepare the damaged fastener for extraction. These drill bits are sized to match the screw extractors and are used to drill a hole into the center of the broken or stripped fastener before using the extractor.
3. Tap Wrench or T-Handle: A tap wrench or T-handle may be included to provide a secure grip and precise control when using the screw extractors or drill bits. This tool allows for easy turning and maneuvering during the extraction process.
4. Storage Case: All components are typically housed in a durable storage case or organizer, featuring compartments or slots for each extractor, drill bit, and accessory. The case keeps the tools organized, secure, and easily accessible.

How to Use a Screw Extractor & Drill Set:

1. Assessment: Begin by assessing the size and condition of the broken or stripped fastener. Determine the appropriate size of the screw extractor and matching drill bit needed for extraction.
2. Drilling: Use the matching drill bit from the set to drill a hole into the center of the broken or stripped fastener. The size of the drill bit should match the size of the screw extractor being used.
3. Inserting the Extractor: Once the hole is drilled, insert the screw extractor into the hole, ensuring it’s securely seated and aligned with the fastener.
4. Turning the Extractor: Use a wrench, tap wrench, or T-handle to turn the screw extractor counterclockwise. The reverse threads on the extractor will grip the inside of the broken or stripped fastener and gradually loosen it from the material.
5. Removing the Fastener: Continue turning the extractor until the broken or stripped fastener is fully removed from the material. Use caution to avoid applying excessive force, which could damage the surrounding material.
6. Clean-Up: After extraction, clean any debris or residue from the hole and surrounding area. Inspect the material for any damage and make any necessary repairs or adjustments.
