A Torx TX 50 Impact Insert Bit 25mm (2pc, Carded) is a high-quality screwdriver bit designed for use with Torx screws (star-shaped drive). The TX 50 size refers to the specific size of the Torx drive, which is larger than other sizes, commonly used in heavy-duty applications like automotive or construction. The 25mm length provides the right reach for most tasks, and the impact design ensures that the bit can handle high-torque and high-impact applications, making it suitable for use with impact drivers. The 2pc carded packaging means the bit is sold in a pack of two, and it is conveniently packaged for retail display.
