The Bosch EXPERT PH2 Tic Tac Box Extra Hard Phillips Screwdriver Bits are professional-grade PH2 bits engineered for reliable, universal screw-driving across a wide range of applications. Manufactured from S2 Modified Steel with an optimised heat treatment process, these bits deliver an extra-hard construction that holds up under demanding conditions. This makes them a dependable choice for carpenters, electricians, and general contractors who require consistent performance throughout the working day. Each bit features a tapered torsion zone that absorbs torque peaks, force, and vibrations during screw-driving, helping to protect both the bit and the fastener. The 1/4" external hex shank ensures a secure, positive connection with maximum torque transmission in three-jaw chucks and standard 1/4" internal hex tool holders. At 25mm in length, these bits are suited to use with screwdrivers and drill drivers where compactness and precision are important.
