Makita double-ended screwdriver bit PH1 — 90 mm

Makita double-ended screwdriver bit PH1 — 90 mm is a replaceable bit designed for fastening Phillips-head screws. With PH1 tips at both ends and a 90 mm overall length, this bit is suitable for use with manual holders and power bit drivers. The compact length balances reach and control for general repair, assembly and construction tasks where standard PH1 screwdrivers are required.

Advantages

This double-ended bit provides two PH1 working ends in a single tool, reducing the need to carry multiple bits. The 90 mm length offers moderate reach into recessed screw positions while still fitting common holders and quick-change chucks. Precision-formed Phillips tips improve engagement with screw heads, helping to reduce cam-out and wear during repeated fastening operations.

Suitable for

• Assembly of furniture and fixtures using PH1 screws
• General repair and maintenance tasks with Phillips-head fasteners
• Electrical and electronic enclosures requiring moderate screw depth access
• Construction and finishing work involving PH1 screws

Key specifications

• Tip type: Phillips PH1 at both ends
• Overall length: 90 mm
• Compatibility: fits standard bit holders and quick-change drivers
• Material: hardened steel for durability and wear resistance
• Finish: corrosion-resistant surface treatment

How to use

Insert one end of the double-ended bit into a compatible bit holder or power driver and secure according to the tool manufacturer's instructions. Engage the matching PH1 screw head, apply steady axial pressure, and drive at appropriate speed to avoid slipping. When the tip becomes worn or damaged, rotate the bit or switch to the other end; replace the bit when both ends show significant wear to maintain reliable fastening performance.

Usage recommendations

Use the bit with drivers that support 1/4" hex shanks and recommended torque settings for PH1 screws. Avoid excessive side load and high torque beyond the screw and driver specifications to prevent tip damage. Store bits in a dry, organized case to prolong service life and ensure correct tip selection for each task.
