Haglöf Increment Borer Chuck for Electric Drills
Core into the sidewall of an individual board to desired depth, and back out the bit. Cores remain inside the bit until next core sampled pushes it out. Drill into the end grain of a board to remove the last core. The end grain core remains in place when the bit is reversed because of the wood’s horizontal grain. Use with a minimum drill size of 1/2”.
