Screwdriver Bit PH1 x 50 mm, GRAPHITE 57H978, Phillips PH1 precision tip

GRAPHITE PH1 x 50 mm screwdriver bit (model 57H978) is a precision Phillips PH1 tip designed for use with compatible bit holders, manual screwdrivers and power drivers that accept standard 1/4" hex bits. With a 50 mm length it provides reach for recessed or partially obstructed screws while maintaining control for medium-size Phillips fasteners commonly found in furniture assembly, electrical installations and general DIY tasks.

Advantages

The precision-machined PH1 tip ensures accurate engagement with Phillips screw heads, reducing cam-out and wear. Hardened steel construction offers durability for repeated use and reliable torque transfer. The 50 mm shaft length strikes a balance between reach and control, allowing access to screws in narrow or semi-recessed locations while remaining stable in bit holders and power drivers.

Suitable for

• Assembling flat-pack furniture and cabinets
• Electrical and lighting installations with medium Phillips screws
• General household repairs and DIY projects
• Using with manual bit holders, ratchets or cordless drivers

Key specifications

• Tip type: Phillips PH1 precision tip
• Length: 50 mm overall shaft length
• Drive interface: standard 1/4" hex shank compatible with common bit holders and drivers
• Material: hardened steel for wear resistance and torque transfer
• Finish: industrial coating for corrosion resistance and smooth insertion

How to use

Insert the 1/4" hex shank of the PH1 bit into a compatible bit holder, manual screwdriver handle or power driver. Ensure the bit is seated securely before applying torque. Align the precision PH1 tip with the Phillips screw recess and apply steady pressure while driving to minimise slipping or cam-out. For power drivers, use appropriate speed and clutch settings to avoid overdriving or damaging screw heads and surrounding materials.

Usage recommendations

Use the PH1 x 50 mm bit for medium-size Phillips screws; replace the bit if the tip shows rounding or excessive wear. Match torque and speed to the screw and material to prevent stripping. Store bits in a designated case or holder to protect the precision tip and prolong service life.
