Screwdriver bit GRAPHITE 56H575, 1/4" drive, Phillips PH1, 150 mm

GRAPHITE 56H575 screwdriver bit, 1/4" drive, Phillips PH1, 150 mm is a single long-reach driver bit designed for use with manual and powered drivers that accept 1/4" (6.35 mm) hex shanks. Made from S2 grade alloy steel, the PH1 tip is intended to secure and remove medium-duty cross-headed (Phillips) screws commonly found in carpentry, furniture assembly and general repair tasks. The 150 mm length provides extended reach for recessed fasteners and working in confined assemblies; the bit is supplied in a blister pack for convenient storage.

Advantages

The bit's S2 alloy steel construction resists deformation and delivers repeatable tip geometry for consistent engagement with Phillips screws. Its 1/4" hex shank fits standard chucks and quick-change holders, enabling fast swapping between bits. The extended 150 mm length improves access to hard-to-reach screws while maintaining sufficient rigidity for medium-duty fastening. Lightweight construction keeps the bit easy to handle during prolonged use.

Suitable for

• Assembly and disassembly of furniture and cabinetry
• Electrical installations where Phillips screws are used
• General repair and maintenance tasks involving medium-duty fasteners
• Work requiring extended reach into recessed or deep screw positions

How to use

Insert the 1/4" hex shank into a compatible chuck, quick-change holder or screwdriver with a 1/4" receptacle, ensuring it locks securely. Align the PH1 tip with the screw head and apply steady axial pressure while turning the driver. For powered drivers, select an appropriate torque setting to avoid cam-out or screw head damage. After use, store the bit in its blister pack or a designated bit holder to protect the tip.

Usage recommendations

Use this PH1 150 mm bit for medium-duty Phillips screws and avoid excessive torque beyond recommended settings for the screw and tool. Inspect the tip regularly for wear or rounding and replace the bit if engagement becomes unreliable. For prolonged exposure to moisture, dry and lightly lubricate the bit to limit corrosion despite the material's resistance.
