Screwdriver bit GRAPHITE 56H543, 1/4" drive, 50 mm length

GRAPHITE 56H543 screwdriver bit with a 1/4" drive and 50 mm length is a medium-length accessory intended for use with standard 1/4" bit holders, drills, impact drivers and manual screwdrivers. The bit is made from S2 steel and includes a torsion zone that reduces transmitted peak forces under high torque. The working tip is machined to ensure accurate seating in screw heads, making the bit suitable for repetitive fastening tasks in household and workshop environments.

Advantages

The S2 steel construction provides increased flexibility and improved resistance to mechanical damage compared with basic tool steels. A built-in torsion zone absorbs peak torque, limiting stress on the tip and reducing the risk of breakage during heavy-duty use. The precisely formed working tip ensures a secure fit in screw heads, improving driving accuracy and reducing cam-out. At 50 mm length and approximately 28 g weight, the bit balances accessibility in recessed areas with stable handling in power tools.

Suitable for

• Driving and removing screws in household repairs
• Assembly and disassembly tasks in a workshop
• Use with drills and impact drivers where higher torque is required
• Manual fastening using standard 1/4" bit holders

Key specifications

• Drive: 1/4"
• Overall length: 50 mm
• Material: S2 steel
• Tip type: PH1/2/3 compatible working tip
• Design feature: torsion zone for torque absorption
• Typical weight: 28 g

How to use

Insert the 1/4" drive end securely into a compatible bit holder, chuck or impact driver. Select the appropriate PH tip size that matches the screw head to avoid cam-out. When using power tools, set the tool to the correct torque or impact setting for the fastener and material. Apply steady, axial pressure during driving to maintain tip engagement and minimise wear on the working tip. After use, inspect the tip for rounding or damage and replace the bit when fit or performance degrades.

Usage recommendations

For prolonged service life, use the bit with the correct PH size for the screw and avoid excessive side loads. When working with high-torque impact drivers, the torsion zone helps protect the tip but periodic inspection and replacement when visibly worn will maintain driving accuracy and safety.
