Portabit per cacciavite Wera 895/4/1

The Wera 895/4/1 screwdriver bit holder is a compact accessory designed to hold and secure interchange able screwdriver bits with a 1/4" (6.35 mm) hex shank. With an overall length of 77 mm and a diameter of approximately 14.3 mm, the holder provides a balanced combination of reach and control for manual and powered drivers. The design focuses on positive bit retention and smooth insertion, allowing reliable transfer of torque and improved handling in a variety of fastening tasks.

Advantages

The bit holder offers secure retention for standard 1/4" bits while remaining easy to operate when changing bits. Its 77 mm length gives extra reach for recessed fasteners without significantly compromising control. The compact diameter and ergonomic profile contribute to comfortable handling, and the hex shank fits common quick-change chucks and driver adapters. The construction is intended to provide consistent engagement between driver and bit for efficient torque transmission.

Suitable for

• General assembly and maintenance work with 1/4" screwdriver bits
• Working in confined or recessed spaces where extra reach is required
• Use with cordless drivers, electric screwdrivers and manual bit holders
• Professional and DIY fastening tasks requiring reliable bit retention

Key specifications

• Hex shank: 1/4" (6.35 mm)
• Length: 77 mm
• Outer diameter: 14.3 mm (approx.)
• Compatibility: fits standard 1/4" screwdriver bits and quick-change chucks
• Intended use: bit retention and torque transmission for fastening applications

How to use

Insert a compatible 1/4" bit into the holder until it seats securely; the retention mechanism will hold the bit in place. Fit the hex shank into the driver chuck or quick-change adapter and ensure it is locked before applying torque. For removal, release the retention mechanism as specified by the driver system and withdraw the bit. Use steady, aligned pressure when driving screws to maintain engagement between bit and fastener and to avoid slippage.

Recommendations

Inspect bits and the holder for wear or damage before use. Use bits that match the fastener head type and size to minimize cam-out and maximize lifespan. Avoid excessive side loads and impacts to protect the retention mechanism; keep the holder and bits clean and free of debris for reliable operation.
