Power screwdriver / impact driver Proline 66371, cordless function, 1 pc

Proline 66371 is a compact cordless power screwdriver and impact driver combination supplied as a single unit. Designed for general DIY, assembly and repair tasks, this handheld tool integrates an impact mechanism with a double hammer clutch and a universal 1/4" quick coupling to handle a range of fastening and light drilling jobs. The tool features a left/right direction switch and selectable torque settings to support controlled fastening and loosening operations.

Advantages

The integrated impact mechanism with a double hammer clutch delivers short, high-torque impacts that improve fastening efficiency while reducing the risk of bit cam-out. A compact composite body with a rubber-covered handle provides a secure grip and reduced vibration during use. Multiple torque positions and a dedicated loosening position allow for precise control over tightening stages. The universal 1/4" quick coupling enables fast bit changes and compatibility with standard hex bits.

How to use

Before use, fit a compatible 1/4" hex bit into the quick coupling and ensure the battery is charged and correctly installed. Select the required direction with the left/right switch and choose one of the three tightening torque positions for fastening or the dedicated loosening position for removal. Hold the tool by the rubber-covered handle, position the bit on the fastener, and apply steady pressure while operating the trigger. Use short bursts when starting or when working near fragile material to avoid over-tightening.

Usage recommendations

For consistent results, use bits in good condition and appropriate size for the fastener. Keep the downward air inlet free of debris to maintain cooling and motor performance. Inspect the composite housing and rubber grip regularly; replace worn bits and recharge batteries according to manufacturer guidance to prolong tool life.
