Spiral-flute extractors have tapered counterclockwise threads to remove right-hand fasteners when the extractor is turned counterclockwise. Extractors grip the inside edges of a hole that's been predrilled in the fastener shaft.

Straight-flute extractors have four straight, tapered sides that cut straight into the fastener to remove right- and left-hand threads. Straight-flutes don't enlarge or expand the hole, making them a good choice for working with pipes and fittings. Extractors grip the inside edges of a hole that's been predrilled in the fastener shaft.

Double-ended extractors have a drill bit on one end to create a starting hole and an extractor on the other end to remove the fastener. Drill bits are sized to be compatible with the extractor. Double-ended extractors take up less space and ensure size compatibility over separate drill bits and extractors.

Single-ended extractors have a bit and extractor on the same end of the tool to drill and extract broken fasteners in a single operation. It can be used in a reversible drill or a hex-head screwdriver.
