DeWalt 25mm screwdriver Phillips PH2 bits in the 'Tough Case' compatible holder. This item fits the Dewalt T-STAK caddy. These DeWalt PH2 screwdriver bits are designed for professional use. They provide a high-quality screwing action attached to your power drill. The flexible torsion zone on each bit absorbs stress caused by excessive tightening, and so reduces breakages. The extra definition on the driver ends means you can avoid wear and rounding on the heads as you drive your screws home. The extra-thick construction of each bit stops the shuddering that would otherwise disrupt your drill action as you work. These bits have optimised tip geometry with less than 4 degrees movement for precise rotation in use. You can use them with magnetic holders for easy changes and a secure hold in your drill. The 25 pieces come in a hard plastic container to keep them together and well protected during transit and storage. They are made from steel (s2 grade) and are strong and durable with a hardened bit core for extra strength & durability. Especially suited for repetitive screwdriving tasks and ideal for driving fasteners into wood, metal, plastic and drywall materials.
