Bit insert GRAPHITE 10x65 mm 1/4" magnetic 57H993

Magnetic bit insert GRAPHITE 10x65 mm 1/4" (model 57H993) is a replaceable screwdriver bit designed for standard 1/4" hex chucks. With a length of 65 mm and a 10 mm shank diameter, it provides extended reach for accessing recessed or hard-to-reach fasteners. The magnetic tip holds screws securely for easier single-handed operation and improves alignment during assembly and repair work. The bit is compatible with electric screwdrivers, manual bit holders and impact drivers that accept 1/4" hex bits.

Advantages

The bit's 65 mm length enables access to fasteners located in deep or narrow cavities while the 10 mm shank diameter ensures a stable fit in standard holders. The integrated magnet at the tip reduces the risk of dropping screws and speeds up repetitive fastening tasks. Constructed to fit common 1/4" hex chucks, the insert is easy to install and remove, making it suitable for both professional tradespeople and DIY users performing repair, maintenance or assembly operations.

Suitable for

• Assembly and disassembly of recessed screws in furniture and cabinetry
• Maintenance and repair tasks in construction and mechanical workshops
• Installation of fixtures where reach and screw retention are required
• Use with electric screwdrivers, cordless drivers and manual bit holders

Key specifications

• Bit type: removable screwdriver bit with 1/4" hex shank
• Length: 65 mm
• Shank diameter: 10 mm
• Tip feature: magnetic tip for screw retention
• Intended use: fastening and loosening screws in recessed or hard-to-reach locations

How to use

Insert the 1/4" hex shank into the chuck or bit holder of the screwdriver until it locks securely. Position the magnetic tip on the screw head to allow the magnet to hold the screw in place, then apply steady axial pressure while operating the screwdriver at an appropriate speed and torque setting. For removal, reverse the direction and maintain control to prevent the screw from falling once loosened. Remove the bit by pulling it out of the holder when the task is complete.

Usage recommendations

Use the bit with properly matched torque settings and avoid excessive side load to prevent premature wear. Keep the magnetic tip free of metal debris and store the bit in a dry place. Replace the bit when the tip shows clear signs of wear or damage to maintain secure engagement with screw heads.
