## Long description

Proline ZR18646 is a single 1/2" drive screwdriver bit with a length of 55 mm, designed as a replaceable insert for socket drivers, impact adapters and compatible hand tools. The bit is intended for use in assembly, maintenance and repair tasks where a robust 1/2" drive interface is required and a medium-length bit provides access without excessive leverage loss.
Advantages
The bit offers a standardized 1/2" drive connection for secure attachment to compatible tools and adapters. Its 55 mm length balances reach and control, making it suitable for working in moderately recessed fasteners while retaining stability. Supplied as a single piece, it can be used as a direct replacement in tool sets and reduces downtime when a specific drive size is required.

 Assembly of mechanical components using 1/2" drive tools

 Quantity: 1 piece

How to use
Insert the bit into a matching 1/2" drive socket, impact adapter or hand tool until it locks or seats securely. Use the appropriate tool and torque settings for the fastener and material to avoid damage. For impact applications, ensure the bit is rated for impact use and the adapter or holder is compatible. After use, remove the bit by releasing the retaining mechanism on the driver or adapter and store it in a suitable bit holder or toolbox.
Usage recommendations
Use the bit with tools that match the 1/2" drive specification and select correct torque or impact settings for the fastener type. Inspect the bit for wear before use and replace it if deformation or significant wear is present to maintain safe and reliable fastening performance.
