Advantages

The small case saves space and keeps bits organized for transport and storage.

Suitable for

• Household repairs and furniture assembly
• Installing fixtures and light fittings

• Light professional use where portable bit sets are required

Key specifications

• Number of pieces: 10
• Material: S2 tool steel
• Compatibility: standard 1/4" hex bit holders and quick-change chucks
• Intended use: manual and powered screwdrivers
• Storage: compact carrying case for organization

How to use

Select the bit matching the screw head profile and insert it into a compatible 1/4" hex holder or the screwdriver chuck until it seats securely. For powered tools, set an appropriate torque or speed to avoid stripping fasteners; for manual use, apply steady pressure while turning. Change bits by pulling them from the holder and replacing with the required size, and store bits back in their case after use to prevent loss and maintain organization.

Usage recommendations

To prolong bit life, avoid excessive torque beyond the rated strength of S2 bits, use the correct bit size for the screw head, and keep bits clean and dry. When using with power tools, start at low speed and increase gradually, and use torque control where available to prevent damage to fasteners and bits.
