The BRILLIANT TOOLS HSS screw extractor set BT541900 is a 25-piece kit designed for vehicle repair and general maintenance tasks. It permits professional removal of broken, rusted or rounded screws and dowel pins and is suitable for professionals, mechanics and DIY users. The set includes HSS spiral drills in sizes 3.2, 4.8, 6.4, 8.0 and 8.7 mm, drill guide bushes, specially shaped extractors (king pins) and an adapter for unscrewing, all supplied in a sturdy plastic case.

Advantages

The kit reduces time and costs by enabling controlled removal of damaged screws and bolts between 5 and 16 mm (3/16"–9/16"). High-speed steel (HSS) spiral drills provide reliable cutting performance and the centring drill guide bushes make it easy to find the correct centre on small screws and threaded rods without a centre punch. The supplied adapter and extractors allow secure engagement and safe unscrewing with standard tools.

How to use

Secure the workpiece and select the appropriate HSS drill size for the screw or threaded rod. Use the drill guide bush to centre the drill on the screw or rod and drill a pilot hole to the required depth. Choose the matching extractor (king pin) and drive it into the pre-drilled hole with a hammer until its flanks engage the material. Fit the adapter onto the extractor and turn with a screw spanner or adjustable wrench to unscrew and remove the damaged fastener.

Recommendations

Wear appropriate personal protective equipment (eye protection and gloves). Use steady, controlled drilling to avoid further thread damage. For heavily corroded fasteners, apply penetrating oil before starting and work incrementally with the correct drill and extractor sizes. Store the set in its case to protect tools and parts.
