Screwdriver bit Proline 58505, length 100 mm, 1 piece

Proline 58505 screwdriver bit, 100 mm length, single piece designed for use with manual and powered screwdrivers.

The bit is intended as a spare or replacement component and is compatible with standard bit holders and magnetic bit adapters used in general repair and assembly work.

Advantages

The 100 mm length gives added reach compared with standard short bits, allowing access to screws located deep inside assemblies or behind obstructions. Manufactured by Proline with a focus on functional durability, the bit provides consistent engagement with screw heads and stable performance when used with both manual handles and power drivers. The single-piece format simplifies inventory and replacement needs for workshops and DIY toolkits.

How to use

Insert the Proline 100 mm bit into a compatible 1/4" hex bit holder, magnetic adapter or directly into the chuck of a suitable power driver. Ensure the bit is seated securely before applying torque. Use appropriate torque settings on powered drivers to prevent cam-out or damage to the screw head. After use, store the bit in a rack or bit holder to protect the tip and maintain readiness for future tasks.

Usage recommendations

Choose the correct screw head profile and size to match the bit tip. When working with power tools, start at low speed and progressively increase torque as needed. Inspect the bit tip regularly for wear and replace it when signs of rounding or damage appear to maintain safe and efficient fastening.
