We developed these tools for cutting accurate neck joints for a traditional Martin dovetail.
Each custom made cutter bit is carbide-tipped for long life, with a 1/4"-diameter shank and a 1/2" guide bearing. A small length of heat-resistant tubing is supplied with the cutter bit to keep the bearing from riding up the shank.
Designed for use with our Acoustic Neck Joint Routing Templates (sold separately).
