Extractor

The extractors are produced in stainless steel with metallic head and special design for easy core extraction of the wood core.

When the required depth has been reached – usually the pith of the tree, insert the extractor upside down into the borer bit. The edges on the extractor should be facing downwards. Press the extractor inside the borer core tube. Turn the borer handle half a turn counterclockwise. By doing this half turn back, the tree core breaks off, and the extractor edges are now facing upwards. Pull the extractor out, with the core securely kept in place by the toothed end of the extractor. To avoid decay in the trunk, it is recommended to bore a tree only every five or six years and to resinsert the core in the hole after reading.
