Technical Specifications: Descriptions: This square hole drill bit cannot be used with an electric drilling machine. The drill bit must be used with a square hole drill (using a drill press or tap).

The standard flute drill bit is designed to facilitate the removal of wood chips and improve drilling efficiency. The precise grinding process results in a cleaner and more durable finish. Features: Square hole drill bits cannot be used with an electric drilling machine. Drilling square holes requires a square hole drill bit (for both standard and conical drilling machines). A square hole drill bit is drilled using a combination of a sleeve and an outer sleeve. This reduces the workload for construction workers, accelerates construction speed, and lowers construction costs for the building, installation, renovation, and decoration industries. The precise grinding process results in a cleaner and more durable finish. The standard flute drill bit is designed to facilitate the removal of wood chips and improve drilling efficiency. Square hole drill bits are primarily used in woodworking applications.
