Screwdriver bit set GRAPHITE 56H542 — 1/4" drive, Philips PH1 PH2 PH3, 50 mm length

GRAPHITE 56H542 is a set of Phillips (PH) screwdriver bits for a 1/4" hex drive, including sizes PH1, PH2 and PH3. Each bit measures 50 mm in length and is suitable for use with manual screwdrivers, cordless drivers and powered screwdrivers that accept a 1/4" holder. The bits are manufactured from S2 steel with a dedicated torsion zone to improve flexibility under load and reduce the risk of breakage. With a lightweight total kit weight of 28 g and precision-machined tips, this set is intended for general fastening tasks in construction, furniture assembly and routine maintenance.

Advantages

The bits are made from high-quality S2 steel, providing increased resistance to mechanical damage and wear. A built-in torsion zone helps absorb shock and high torque peaks, reducing stress on the working tip and extending service life. Precision-ground tips ensure accurate engagement with Phillips fasteners, minimising cam-out and slippage. Their 50 mm length offers a balance between accessibility in recessed fasteners and control during manual work. The compact, lightweight set is easy to carry and store.

Suitable for

• General fastening in construction and renovation
• Furniture assembly and cabinet installation
• Maintenance and repair of household appliances
• Electrical and plumbing fixtures where Phillips screws are used
• Use with manual screwdrivers, cordless drivers and impact drivers with 1/4" bit holder

How to use

Select the appropriate Phillips size (PH1, PH2 or PH3) that matches the screw head. Insert the 1/4" hex shank of the bit into the screwdriver or driver chuck until it seats firmly. Apply steady pressure and operate at the recommended speed for the tool in use; reduce speed or torque when driving smaller screws or into delicate materials. For impact driving, ensure the driver is set for the correct mode and hold the tool steadily to keep the bit engaged with the screw head. After use, inspect tips for wear and replace bits if rounded or damaged.

Usage recommendations

Use the PH2 bit for most standard Phillips screws encountered in construction and furniture; reserve PH1 for smaller screws and PH3 for larger fasteners. When using with impact drivers, check compatibility with the tool and avoid excessive torque settings to prolong bit life. Store bits in a dry place and replace them if the tip shows signs of deformation or increased cam-out.
