Bitholding screwdriver Wera 145 mm ratchet mechanism 109 g

Bitholding screwdriver with a 145 mm length and a weight of 109 g, equipped with an integrated ratchet mechanism that speeds up screwdriving without frequent repositioning of the tool. The ratchet has fine toothing (36 teeth, 10° return angle) embedded in the handle and allows ergonomic switching between clockwise, counterclockwise and neutral positions. The Kraftform Plus handle supports comfortable use and reduces the risk of blisters. The screwdriver accepts 1/4" external hexagon bits (DIN ISO 1173-C 6.3 / E 6.3) and features a Rapidaptor quick-release chuck combined with a strong permanent magnet to hold bits securely for fast bit changes.

Advantages

The integrated ratchet mechanism with 36 teeth and a 10° return angle enables precise and faster screwdriving without having to reposition the tool. The ratchet is fully embedded in the handle, making operation tidy and effortless. The Kraftform Plus handle provides ergonomic grip and reduces hand fatigue and blisters. The Rapidaptor quick-release chuck and strong permanent magnet allow very fast and reliable bit changes. Compatibility with standard 1/4" external hexagon bits ensures broad usability.

Suitable for

• Precision fastening and adjustment in assembly work
• General maintenance and repair tasks
• Electronics and small mechanical installations requiring 1/4" bits

How to use

Insert a compatible 1/4" hex bit into the Rapidaptor chuck until it locks.

To change bits, press the quick-release mechanism and pull the bit out, then insert the next bit until it clicks into place.

Recommendations

For best results, use bits that conform to DIN ISO 1173-C 6.3 / E 6.3 and keep the Rapidaptor mechanism free of dirt. Avoid applying excessive torque beyond the bit or screw rating to prevent damage. Store the screwdriver in a dry place to protect the magnet and mechanism.
