Screwdriver Impact Bits Dedra PH1/PH2/PH3 x 50 mm, set of 3

Set of three Dedra impact-rated Phillips screwdriver bits in sizes PH1, PH2 and PH3, each 50 mm long. These bits are manufactured for use with impact drivers and impact-ready screwdrivers to drive Phillips fasteners. Supplied in blister packaging, the set is intended for general fastening tasks in woodworking, construction and mechanical repair where durable, impact-resistant tips are required.

Advantages

The Dedra Phillips impact bits combine a hardened tip geometry with a shank designed to withstand repeated percussive loads from impact drivers, reducing tip cam-out and wear during high-torque applications. Their uniform 50 mm length offers balance between accessibility in confined spaces and control during hand-guided operations. Being impact-rated, the bits provide improved service life compared with standard screwdriver bits when used with impact tools.

Suitable for

• Driving Phillips-head screws into wood, drywall and soft metals
• Assembly and disassembly tasks in construction and carpentry
• Mechanical repair and maintenance where impact drivers are used
• General fastening tasks in workshop and site environments

How to use

Select the Phillips size that matches the screw head to ensure proper engagement. Insert the chosen bit into the impact driver's bit holder until it locks securely. Position the screw and apply steady axial pressure while operating the impact driver at the appropriate torque or speed setting. For manual screwdrivers with quick-change chucks, ensure the bit is seated firmly and use controlled force. After use, store the bits in their blister pack or a bit holder to prevent damage and loss.

Usage recommendations

Use the correct Phillips size to minimize cam-out and tip damage. When working with high-tensile or hardened screws, reduce driver speed and apply incremental tightening to avoid overloading the bit. Inspect bits regularly for tip wear and replace when signs of rounding or chipping appear.
