The BlueSpot Screw Extractor Set is designed for DIY enthusiasts and tradespeople who need to remove stripped, snapped, or damaged fasteners ranging from 3mm to 25mm. The primary benefit of this tool is its reverse-thread design, which bites into the metal to safely back out compromised hardware without expanding the hole. While it is an essential recovery tool, users should note that it requires a clean, centered pilot hole to function effectively, meaning it is not a solution for every type of rounded-out bolt head.

It is not recommended to use an impact drill, as the percussive force can snap the extractor bit inside the damaged screw.
Yes, a clean, centered pilot hole is essential for the extractor to gain the necessary purchase to remove the fastener.
This set is designed for fasteners ranging from 3mm to 25mm in diameter.
Extraction can be difficult on hardened stainless steel. Ensure your pilot hole is very clean and use a manual tap wrench to avoid heat-work hardening.
You will need a drill with high-speed steel bits for the pilot hole, and either a reversible power drill or a manual tap wrench for the extraction.
The pilot hole is likely too large or shallow. Deepen the pilot hole or switch to a slightly larger extractor size.
The surface of the broken fastener may be hardened. Use a center punch to create a deeper divot or re-drill the pilot hole.
To ensure the longevity of your BlueSpot extractors, always use a high-quality HSS drill bit for the initial pilot hole, as standard bits may dull against damaged hardware. If you are using a power drill, keep the clutch setting low to prevent over-torquing the extractor. After each use, inspect the threads of the extraction bits for metal shavings and clean them with a wire brush. Apply a light coat of machine oil before storing them in a dry environment to prevent corrosion. The square shank is compatible with most standard tap wrenches, but avoid using impact drivers with these bits as the high-impulse force can cause the tool to snap.
