Proline screwdriver bits PH3 1/4" drive, length 100 mm, set of 2 (model 10803)

Set of two Proline PH3 screwdriver bits with a 1/4" hex drive and 100 mm length. These bits are shaped for Phillips PH3 screws and are intended for use with 1/4" bit holders, manual screwdrivers with hex chucks and compatible impact drivers. The 100 mm length provides extended reach for recessed fasteners or working in tight assemblies while maintaining standard PH3 engagement for reliable torque transfer.

Advantages

Proline PH3 bits are manufactured to deliver consistent fit to PH3 screw heads, reducing cam-out and wear. The 1/4" hex drive ensures compatibility with a wide range of bit holders and quick-change adapters. Their 100 mm length increases accessibility to screws located in deep or confined spaces without requiring additional extensions.

Suitable for

• Driving PH3 Phillips screws in woodworking and furniture assembly
• General repair and maintenance tasks where extended reach is needed
• Use with 1/4" bit holders, quick-change chucks and compatible impact drivers

Key specifications

How to use

Select a compatible 1/4" bit holder or screwdriver with a hex chuck, insert the PH3 bit securely into the holder, then engage the PH3 tip with the screw head. Apply steady pressure and rotate at a speed appropriate for the fastener and material. For impact drivers, ensure the bit is fully seated and use controlled impact settings to prevent overdriving or damage to the screw head.

Usage recommendations

Inspect bit tips before use and replace any bit that shows rounded or damaged edges. Use the correct PH3 size to minimize cam-out. When working with delicate surfaces, reduce torque or use manual control to avoid stripping. Store the bits in a dry place to prevent corrosion.
