The Bosch 3 Piece Extra Hard Phillips Screwdriver Bit Set provides a complete range of Phillips sizes for universal screw-driving across a wide variety of everyday tasks. Manufactured from S2 Modified Steel with an optimised heat treatment process, these bits deliver extra-hard performance that stands up to demanding use. The result is reliable torque transmission whether you're working with a screwdriver or a drill driver. Each bit features a tapered torsion zone designed to absorb torque peaks, force, and vibration during screw-driving. This helps protect both the bit and the fastener, reducing cam-out and wear over time. The ¼" external hex shank ensures a secure connection in three-jaw chucks and standard ¼" internal hex tool holders. Suitable for contractors, joiners, and general tradespeople, this set covers PH1, PH2, and PH3 sizes — the three most commonly used Phillips profiles — making it a practical addition to any tool kit or bit holder.
