cordless drill screwdriver bit

The cordless drill screwdriver bit is made from chrome-vanadium steel with precise heat treatment to provide high tensile strength and long-lasting resistance to wear and breakage. Its standard length ranges from 25 to 100 millimeters, with a shaft diameter of 6.35 millimeters ¼ inch, ensuring full compatibility with cordless drills, electric screwdrivers, and magnetic holders. The bit is produced in flat, Phillips, and cross-head profiles and is designed according to international DIN and ISO standards to provide maximum fit and optimal performance on screws.

The bit surface features black phosphate coating or nickel plating, enhancing corrosion and rust resistance and extending the tool’s service life. Surface hardness is controlled between 58 and 62 HRC, and precise edges ensure uniform torque transfer without slipping. Single-ended or double-ended designs allow easy access to deep screws and optimize use in repair, industrial, and construction projects, maximizing user efficiency and performance.
