Wood Working Mortiser – Tenoning Machine

A mortiser or mortiser is a specialized woodworking machine used to cut square or rectangular holes in a piece of lumber (timber), such as a mortise in a mortise and tenon joint.

Tenoning machines use cutter heads and/or saw blades to form projections (tenons) on pieces of stock. Each tenon can be inserted into a cavity (mortise) on another piece of wood to form a mortise and tenon joint. The figure to the right shows a single-end tenoning machine.
