expansion bit: noun
An expansion bit refers to a drilling tool specifically designed for enlarging existing holes or creating larger boreholes in various materials. It consists of a cylindrical body with multiple cutting edges or specially designed tips. The cutting edges or tips, arranged in a symmetrical pattern around the bit, facilitate the expansion of the hole by removing excess material.
Expansion bits are commonly used in various industries such as construction, manufacturing, and woodworking. They are particularly useful when precise and accurate hole enlargement is required. The cutting edges or tips of expansion bits can be made from different materials, including high-speed steel or carbide, to suit the specific application and material being drilled.
These bits are often operated using power tools such as drills or drill presses, providing efficiency and control during the enlargement process. They are especially advantageous when enlarging holes in wood, metal, plastic, or other materials that may require a larger diameter for accommodating fasteners or fittings.
Expansion bits are available in various sizes and designs, including straight shank, hex shank, or reduced shank variations to fit different drilling tools. Their versatility makes them an essential tool for professionals in various industries who require accurate and controlled hole expansion.
