Straight fluted extractor head |
||||
 |
The square head of a straight fluted extractor allows it to be used in a drill. It must be a 4 jaw drill chuck as a 3 jaw chuck will not accept a square shank.
Tools such as a “T” handle wrench, bar type wrench, adjustable wrench or vice grip pliers can connect to a square head. |
|||
 |
Straight fluted extractors are also available with a triangular shaped head for use in 3 jaw drill chucks. | |||
Straight fluted extractor shaft |
||||
 |
Straight fluted screw extractors also have a shaft, usually made from high carbon steel that has been tempered and heat treated for increased strength, to help withstand wear and tear while extracting. | |||
Straight fluted extractor flutes |
||||
 |
The straight fluted extractor has long, gradually tapered flutes so that it can be tapped into a pre-drilled hole in a damaged bolt, screw or stud. It can loosen left hand threads when turned clockwise and right hand threads when turned anti-clockwise. The flutes dig into the damaged object no matter which way you turn the extractor. | |||
