Kärkisarja Wiha slimBit electric 43158

The Wiha slimBit electric 43158 bit set provides slim, insulated bits designed for electrical applications where access to low-lying screws is required. The set contains six bits with Pozidriv and slotted tips (PZ1 and PZ2), manufactured with Wiha slimTECHNOLOGY to reduce blade diameter by up to 33% while maintaining protective insulation. Each insulated slimBit is individually tested to IEC 60900 and rated for safe work on live parts up to 1,000 V AC. The bits are supplied in a compact bit box that keeps profiles visible and organized. Note: the 6 mm slimBits are compatible only with speedE®, slimVario® or TorqueVario®-S electric tools.

Advantages

The slimTECHNOLOGY blades are up to 33% slimmer than conventional insulated bits, enabling access to recessed screws and spring elements without removing insulation. Individual IEC 60900 testing ensures each slimBit meets safety requirements for live electrical work up to 1,000 V AC. The compact, lightweight set (approx. 142 g) and the transparent bit box improve organization and quick identification of Pozidriv and slotted tips.

How to use

Select the appropriate Pozidriv or slotted slimBit for the screw size (PZ1, PZ2) and insert it into a compatible electric handle (speedE®, slimVario® or TorqueVario®-S for 6 mm slimBits). Ensure the bit is fully seated and the handle is set to the correct speed or torque before operating. When working on live parts, verify that the continuous insulation is intact and follow safe working distances and established electrical safety procedures.

Recommendations

Before use, confirm compatibility between the 6 mm slimBits and your electric tool model. Inspect insulation for damage and do not remove or modify protective insulation. Use only as intended for electrical work and follow IEC 60900 guidelines and local safety regulations when working on live circuits up to 1,000 V AC.
