Screwdriver bit set Dedra DED71581 — 2 pieces, Phillips tips, 155 mm length

Dedra DED71581 is a 2-piece screwdriver bit set with Phillips tips, each bit measuring 155 mm in length. Designed for use with power drivers and manual handles, these extended-size Phillips bits provide reach to recessed fasteners and allow for improved access in narrow or deep screw locations. The set delivers basic Phillips driver functionality suitable for general maintenance, household repairs and light professional tasks.

Advantages

The 155 mm length of each bit extends the reach compared with standard bits, enabling work in recessed or hard-to-access screw positions. Phillips tips ensure secure engagement with crosshead screws to reduce cam-out when used with compatible drivers. Supplied as a compact 2-piece set, it offers a simple solution for jobs that require longer bits without adding unnecessary complexity.

Suitable for

• Fastening and loosening Phillips (crosshead) screws in recessed locations
• Use with electric screwdrivers, impact drivers and manual bit holders
• General household repairs and furniture assembly
• Light professional maintenance tasks in workshops or service vans

Key specifications

• Set size: 2 pieces
• Tip type: Phillips (crosshead)
• Length: 155 mm per bit
• Compatibility: standard bit holders and power drivers with matching shank
• Intended use: fastening and assembly of Phillips screws

How to use

Insert the bit into a compatible driver or manual bit holder until it seats securely. Position the Phillips tip in the screw recess and apply steady axial pressure while operating the driver to reduce slipping. For recessed screws, the 155 mm length allows you to reach the screw head without removing surrounding panels. After use, store the bits in a safe place to prevent damage to the tips.

Usage recommendations

Use the bits with drivers that provide controlled torque to avoid over-tightening and potential damage to screw heads. Match the Phillips bit size to the screw size for best engagement. Inspect the tips regularly for wear and replace bits that show rounding or damage to maintain secure fastening.
