CoreJector™ & Dry Wood Borer
Increment Core Ejector
Stuck increment cores are commonplace. Free the stuck part with this simple and safe solution without damaging the care sample of the increment corer. Made from transparent acrylic, simply thread the ejector over the corer end, and the pin at the base pushes the stuck part up through the corer. The corer threads are protected from damage. No moving parts, robust design, available for increment borers from different manufacturers. Can also be used to protect corers in transit or storage. Also available for the 7mm dry wood borers.
