Screwdriver Bit Set Wiha Micro-Bit Set ESD

The Wiha Micro-Bit Set ESD is a compact bit set designed for precise screw fastening in model-making, electronics and precision mechanics. The set includes common small-profile flat, hex (metric) and nut driver bits with a hexagonal shank for secure fit, stored neatly in a robust plastic case. The ESD precision screw handle complies with IEC 61340-5-1 and provides controlled dissipation of electrostatic energy, while a bit ratchet with a 5° switching angle enables powerful fastening even in confined spaces.

Advantages

The set covers almost all common small screwdriver sizes required for micro-fastening tasks. The ESD precision handle offers surface resistance between 10^6 and 10^9 ohm to protect static-sensitive components. Bits are organised and protected in a durable case for easy transport and storage. The included bit ratchet permits both controlled torque application and use in tight areas due to its minimal switching angle.

Suitable for

• Electronics assembly and repair
• Model-making and RC models
• Precision mechanics and fine assembly work

Key specifications

• Contents: flat, hex (metric) and nut driver bits; ESD precision screw handle; bit ratchet
• Handle standard: IEC 61340-5-1 (ESD compliant)
• Surface resistance: 10^6–10^9 ohm
• Ratchet switching angle: 5°
• Shank: hexagonal for secure fit
• Case: robust plastic organiser

How to use

Select the appropriate small-profile bit from the case and insert it into the ESD precision handle or the bit ratchet. For static-sensitive components, use the ESD handle to ensure controlled dissipation of electrostatic energy. Use the bit ratchet when higher fastening force is required or when working in confined spaces; the 5° switching angle allows incremental motion in tight positions. Store bits in the organiser after use to protect tips and maintain order.

Recommendations

For work on static-sensitive electronics, always use the ESD precision handle and follow your facility’s grounding and ESD-protection procedures. Match the bit size precisely to the screw profile to avoid damage to small screw heads.
