Screwdriver Bit Set Koelner/Rawlplug PH2 130 mm 1/4" long Phillips bits for screwdriver 3 pcs

Koelner/Rawlplug PH2 130 mm 1/4" long Phillips bits, set of 3, are designed to extend the working reach of manual screwdrivers and power drivers. Each bit features a PH2 Phillips profile and a 130 mm length with a standard 1/4" hex shank for compatibility with common bit holders and quick-change chucks. The set is intended for fastening tasks in drywall, timber, and general assembly where additional penetration or reach is required.

Advantages

These long Phillips PH2 bits combine extended reach with a standard 1/4" hex connection, enabling use in both cordless drills and manual bit holders. The uniform length and profile across the three-piece set simplify tool changes and help maintain consistent screw engagement. The longer shank reduces the need for improvised extensions and allows access to recessed or hard-to-reach screw positions.

Suitable for

• Fastening screws in drywall where reach behind panels or through channels is needed
• Woodworking and carpentry tasks requiring deeper screw insertion
• General assembly and maintenance with Phillips-head screws
• Use with 1/4" bit holders, quick-change chucks and compatible screwdrivers

When it may not be suitable

The long 130 mm length can introduce greater flex under high torque compared with shorter bits; for heavy-duty fastening where high torque is required, a shorter, thicker bit or a specifically reinforced impact-rated bit may be more appropriate. These bits are standard Phillips (PH2) profile and are not intended for Pozidriv, Torx, Robertson, or other screw heads.

Key specifications

• Tip profile: Phillips PH2
• Length: 130 mm
• Shank type: 1/4" hex
• Quantity in set: 3 pieces
• Compatibility: manual screwdrivers, cordless drills, quick-change chucks with 1/4" bit holder

How to use

Insert the 1/4" hex shank into a compatible bit holder or quick-change chuck and secure it according to the tool manufacturer’s instructions. Align the PH2 tip with the screw head, apply steady axial pressure and operate the driver at an appropriate speed and torque setting to avoid cam-out. For recessed screws or narrow access points, use the full 130 mm length to reach the fastening point while maintaining firm control of the driver.

What to consider before purchase

• Verify that the screws you use have a PH2 Phillips head profile
• Confirm your driver or bit holder accepts a 1/4" hex shank
• Assess whether a long 130 mm bit is suitable for the torque and stiffness demands of your task

Usage recommendations

For best results, use moderate speed and controlled torque when driving screws with long bits to reduce flex and cam-out. Inspect tips regularly for wear and replace bits that show rounding or damage to maintain secure screw engagement.
