set of 5 professional screw extractors, including a broken screw extractor, made of high-speed steel, suitable for removing damaged screws, bolts, and metal pins (natural color).

【High-Speed Steel】 The screwdriver is made of high-speed steel, which has high hardness and is not easy to rust. After heat treatment, it has high wear resistance and is more durable.

【APPLICATION】 The screw extractor kit has two drill bits. First, use the smaller bit to create a hole in the screw (as deep as possible), then attach the extractor to the other end and turn it to remove the screw. Generally, the harder the material, the lower the drill bit's rotation speed should be.

Wide Application】 A screw extractor can help you remove damaged or rusted screws and bolts. The hexagonal handle is suitable for hand drills.

【Suitable Size】 The screw extractor kit has 5 sizes: size 0 can hold screws 1–4 mm/0.04–0.16 inches, size 1 for 3–5 mm/0.12–0.2 inches, size 2 for 4–8 mm/0.16–0.31 inches, size 3 for 5–10 mm/0.2–0.39 inches, size 4 for 6–14 mm/0.24–0.55 inches

Package Contents: The package contains 5 screwdrivers for different needs. They can be used for most common steel and iron screws or bolts. Please note that stainless steel screws may be difficult to drill out.
