Abstract:
A woodworking cutter includes blades (1) and a cylindrical body (4). A blade (1) is spiral-shaped and has a continuously spiral-shaped cutting edge (3). Spiral-shaped grooves (5) are correspondingly provided on the cylindrical body (4) to hold the blades (1). A blade (1) has a serrated surface matching with the serrated surface of a groove (5). The blades are safe, precisely positioned and conveniently installed. When the blades are worn, they can be moved outwardly and installed again. The spiral-shaped cutting edges extending along the cylindrical surface can reduce noises, reduce the power required for cutting, and improve the surface quality of the material being cut.
