Bits are interchangeable tool attachments designed for driving or removing screws and fasteners using manual screwdrivers, electric drills, impact drivers, or power screwdrivers. They are manufactured from hardened alloy steel, chrome vanadium steel, or high-speed steel to provide high strength, wear resistance, and long service life. Bits are available in various types and sizes, including Phillips, flat (slotted), Pozidriv, Torx, Hex, and Square, enabling them to match different screw head designs for a wide range of construction, mechanical, electrical, and maintenance applications.

Operation:
To operate a bit, the appropriate type and size is selected to match the screw head and securely inserted into the tool’s chuck or bit holder. The bit is aligned with the fastener, and controlled force or power is applied to tighten or loosen the screw while maintaining firm contact to prevent slipping or damage. After use, the bit should be cleaned, inspected for wear or breakage, and stored in a designated holder or case to protect it from corrosion and ensure long service life.
