## Summary description

GRAPHITE 56H579 screwdriver bit for 1/4" drive applications. Phillips PH3 tip, 150 mm length, weighing 32 g and supplied in blister packaging. Designed for use with compatible bit holders, power screwdrivers and manual drivers to fasten or remove PH3 screws in construction, assembly and maintenance tasks.

## Long description

GRAPHITE 56H579 is a 150 mm screwdriver bit with a Phillips PH3 tip and a 1/4" (6.35 mm) drive designed for use with bit holders, power screwdrivers and compatible chucks. Manufactured from S2 alloy steel, this 56H579 driver bit resists deformation and is intended for heavy-duty fastening and removal of cross-headed (Phillips) screws in woodworking, furniture assembly and general construction tasks. Supplied in blister packaging, the bit weighs approximately 32 g and provides extended reach for working in deeper or recessed screw locations.
Advantages
The S2 alloy steel construction offers improved hardness and wear resistance compared with standard tool steels, reducing tip rounding and extending service life during repeated use. The 150 mm length provides better access to screws in recessed or hard-to-reach spots while the standard 1/4" drive ensures compatibility with common bit holders and quick-change chucks. The PH3 profile is sized for medium-to-large cross-head fasteners typically found in carpentry and furniture joints, enabling secure engagement and consistent torque transfer.
Suitable for
 Driving and removing Phillips PH3 screws in wood and composite materials
 Furniture assembly and disassembly
 Construction and finish carpentry tasks
 Use with power drivers, impact drivers (confirm compatibility) and manual bit holders with 1/4" chucks
Key specifications
 Tip type: Phillips PH3
 Drive size: 1/4" (6.35 mm)
 Overall length: 150 mm
 Material: S2 alloy steel
 Weight: approximately 32 g
 Packaging: blister
How to use
Insert the 1/4" shank of the GRAPHITE 56H579 bit into a compatible bit holder or chuck and secure it according to the tool manufacturer's instructions. Align the PH3 tip with the cross-headed screw and apply steady axial pressure while operating the driver at an appropriate speed and torque setting for the material and fastener. For manual work, use an appropriate handle or holder; for power tools, select torque settings to avoid stripping the screw head. After use, inspect the tip for wear and store the bit in its blister or a protective case to prevent damage.
Usage recommendations
For long life and consistent performance, avoid excessive side load or levering on the bit, match the PH3 tip to correctly sized Phillips screws, and replace the bit when tip rounding or deformation becomes noticeable. Verify compatibility with impact drivers before heavy-impact use; while S2 steel is durable, repeated high-impact applications may shorten service life.
