Screwdriver Bit Holder Makita E-03442 Hex Shank 25.4 / 4 mm

The Makita E-03442 Screwdriver Bit Holder with a 25.4 / 4 mm hex shank and 123 mm overall length is designed to provide secure bit retention and extended reach for fastening tasks. Constructed for compatibility with common hex-chuck power tools and impact drivers, this bit holder aims to deliver consistent performance when accessing recessed screws or working in tight spaces. The tool is intended for professional tradespeople and DIY users who require a durable accessory for repetitive screwdriving operations.

Advantages

The bit holder provides firm magnetic or mechanical retention depending on bit type, reducing wobble and bit loss during operation. Its 25.4 / 4 mm hex shank ensures stable connection with standard chucks and quick-change adaptors. At 123 mm length, it offers extra reach to access screws in deeper or harder‑to‑reach locations while maintaining control and alignment. The hardened construction is made to withstand repeated insertions and torque typical in fastening work.

Suitable for

• Driving and removing screws in recessed or deep-set fasteners
• Use with cordless drills, impact drivers and powered screwdrivers with compatible hex chucks
• General assembly, cabinetry, furniture fitting and light construction tasks
• Maintenance and repair work where extended bit reach is required

Key specifications

• Shank type: hex
• Shank size: 25.4 / 4 mm
• Overall length: 123 mm
• Material: hardened steel (tool-grade)
• Compatibility: standard 1/4" hex screwdriver bits and compatible power tool chucks

How to use

Insert a compatible 1/4" hex screwdriver bit into the holder until it seats securely. Insert the hex shank into the tool chuck or quick-change adapter and tighten according to the tool manufacturer's instructions. Align the bit with the fastener and apply steady pressure while driving or removing screws. For recessed or deep-set screws, use the extended length to maintain straight alignment and avoid cam-out. After use, remove the bit and store the holder in a tool case or rack to protect the tip.

Usage recommendations

Use the bit holder with bits rated for the torque levels produced by your drill or impact driver. Inspect the holder and bits for wear before each use and replace any worn components to maintain secure retention and safe operation. Avoid excessive side-loading to prolong service life and ensure consistent engagement with fasteners.
