Proline 10817 is a compact screwdriver bit set that includes two 100 mm long bits designed for both manual and powered screwdrivers.

The compact two-piece kit is convenient to store and transport, suitable for professionals and DIY users who need dependable bits for occasional deep-fastening tasks.

• Use with manual screwdrivers, bit holders, and cordless drills

Key specifications

• Quantity: 2 pieces
• Bit length: 100 mm each
• Mount type: 1/4" hex shank (standard compatibility)
• Intended use: manual and powered screwdrivers
• Application areas: general repair, assembly, maintenance

How to use

Select the appropriate bit for the screw type and insert the 1/4" hex shank into the screwdriver chuck or bit holder until it seats securely. For manual operation, use a compatible handle or bit holder; for power tools, ensure the drill or driver is set to the correct speed and torque. Apply steady pressure and keep the bit aligned with the screw to avoid cam-out. After use, withdraw the bit and store the set in a dry place to prevent corrosion.

Usage recommendations

Use these 100 mm bits when screws are recessed beyond the reach of standard short bits. When working with fragile materials or small fasteners, reduce torque settings on power tools to prevent damage. Regularly inspect bits for wear and replace them if tips become rounded to maintain secure fastening and reduce the risk of slipping.
