Kärjenpitävä ruuvinväännin Wera 812/1 vahvalla kestomagneetilla

The Wera 812/1 bitholding screwdriver features a strong permanent magnet that secures bits firmly during use. It has a Kraftform handle with hard gripping zones for fast operation and soft zones to ensure efficient torque transfer. The tool accepts 1/4" hexagon drive bits according to DIN ISO 1173-C 6.3 and is compact and lightweight for precision tasks.

Advantages

The permanent magnet holds bits reliably, reducing the risk of drops and improving one-handed operation. The Kraftform Plus handle combines comfort with control, enabling both high working speeds and effective torque transmission. The screwdriver’s compact dimensions and low weight support accurate work in confined spaces.

How to use

Select a compatible 1/4" hex bit and insert it into the screwdriver tip; the permanent magnet will hold the bit in place. Use the Kraftform handle to position the bit on the fastener and apply torque with a controlled grip—use the harder zones for faster turning and the softer zones for higher torque transfer. Change bits by pulling the bit out of the holder when needed.

Recommendations

For best results, use bits that conform to DIN ISO 1173‑C 6.3 and keep the magnet and bit seating clean from debris. Avoid excessive side loads on the bit to prevent damage to the bit holder and the fastener.
