A hook tooth is a type of tooth geometry found on band saw blades, characterized by a deep gullet, a positive rake angle, and large, widely spaced teeth. Hook tooth blades are designed for aggressive cutting and fast material removal in wood, plastic, or soft metals. The hook tooth geometry provides efficient chip clearance, reducing heat buildup and blade clogging. However, it may produce a rougher cut surface compared to other tooth geometries, such as skip or regular tooth.
