Combination screwdriver Wera ESD/11 SB – 1-piece, Torx/Philips/Cross/Flat tips, plastic handle (black/yellow)

Wera ESD/11 SB is a single-piece combination screwdriver designed for electrostatic-sensitive environments. The tool accepts 4 mm half-moon (Wera series 9) and 4 mm HIOS (Wera series 21) bits and provides electrical surface resistance below 10^9 ohm in accordance with DIN EN 61340-5-1, reducing the risk of electrostatic damage during precision mechanical and electronic work. The compact Kraftform Micro handle with interchangeable blade system enables quick bit changes; the handle includes a twist cap and free-turning zone for rapid twisting without repeated repositioning of the fingers, plus a power zone with integrated soft areas to transfer higher tightening and loosening torque and a precision zone near the blade for fine adjustment work.

Advantages

The screwdriver combines ESD protection with a compact interchangeable-bit system for fast, secure bit fixation: simply push the bit into the insert for automatic locking and push the sleeve forward to remove it. The free-turning sleeve guides the tool during screwdriving while the power and precision zones on the handle support both higher torque tasks and delicate adjustments. Bits are suitable for manual use and for power tools including electric screwdrivers such as HIOS, Delvo and Sehan.

Suitable for

• Precision assembly and repair of smartphones and mobile devices
• Camera and small-electronics service
• Electronic component and circuit board maintenance
• Dental laboratory and dental surgery instrument work

How to use

Select the appropriate bit for the screw type, push the bit into the tool’s insert until it automatically locks, then position the screwdriver on the fastener. Use the free-turning sleeve and twist cap for rapid turning motions and fingertip guidance; apply higher torque using the power zone of the handle when loosening or tightening larger fasteners. To remove or change a bit, push the sleeve forward and extract the bit. Bits supplied are compatible with manual operation and with suitable electric screwdrivers.

Recommendations

Use the Wera ESD/11 SB in ESD-protected workstations and follow standard electrostatic discharge handling procedures. Choose the correct bit type and size to avoid damaging screw heads and use controlled torque when working on delicate electronics or dental instruments.
