Insulated Precision Screwdriver Wiha 44242 — precision tip, insulated shaft for electrical work

Insulated Precision Screwdriver Wiha 44242 — a tool designed for accurate work on small fasteners while providing electrical insulation for safer operation on live circuits up to the specified insulation rating. The screwdriver combines a fine precision tip for tight tolerances with an insulated shaft and handle that reduce the risk of electric shock during electronics repair, electrical maintenance, and precision assembly tasks.

Advantages

The precision tip ensures secure engagement with small screw heads, minimizing cam-out and damage to delicate components. The insulated shaft and ergonomically shaped handle provide user protection and improved torque control during prolonged use. The tool’s construction emphasizes dimensional accuracy and electrical safety suitable for tasks where both precision and protection are required.

Suitable for

• Repair and adjustment of electronic devices and circuit boards
• Electrical maintenance on live or de-energized installations within the insulation rating
• Precision assembly of small mechanical or electrical components
• Field service work where compact, insulated hand tools are required

Key specifications

• Tool type: insulated precision screwdriver with fine tip
• Tip geometry: precision-machined for small screw heads
• Insulation: insulated shaft and handle for electrical protection up to the product's rated voltage
• Handle: ergonomically shaped for controlled torque and comfort
• Intended use: electronics, electrical maintenance, precision assembly

How to use

Select the correct tip size for the screw to ensure full seating of the precision tip. Before working on electrical installations, verify the product’s insulation rating and observe applicable safety procedures. When using the screwdriver on live circuits, use only within the specified insulation limits and avoid applying excessive lateral force that could damage the tip or compromise insulation. Apply steady, controlled torque and maintain proper hand placement on the handle for optimal control.

Usage recommendations

Regularly inspect the insulated shaft and handle for signs of wear, cracking, or damage; if any damage is present, discontinue use on live circuits. Keep the precision tip clean and free of debris to maintain accurate engagement with fasteners. Use appropriate personal protective equipment and follow local electrical safety standards when working on energized equipment.
