Insulated groove pliers are a type of hand tool commonly used in electrical and plumbing work. They are characterized by their adjustable jaw size, which can grip various shapes and sizes of objects. The "groove" refers to the series of channels along the handles that allow the user to adjust the width of the jaws.

Key Features:

1. Insulation: The handles of these pliers are insulated, providing protection against electrical shocks. This makes them particularly useful for electricians who work with live electrical circuits. The insulation is typically rated to withstand certain voltage levels, and it is important to use pliers with the appropriate insulation rating for the task at hand.

2. Groove Design: The adjustable groove or channel along the handle allows the jaws to open to different widths. This versatility makes groove pliers useful for gripping, twisting, or turning objects of various sizes, such as pipes, bolts, and other hardware.

3. Jaw Shape: The jaws often have a serrated or toothed surface, providing a better grip on objects. The design of the jaws can vary, with some being flat, rounded, or curved to accommodate different tasks.

Common Uses:

• Electrical Work: Safely gripping and manipulating wires, cables, and other electrical components.
• Plumbing: Tightening or loosening pipe fittings and other plumbing hardware.
• General Maintenance: A wide range of tasks requiring a secure grip, such as loosening stubborn bolts or gripping irregularly shaped objects.

When using insulated groove pliers, it's crucial to ensure that the insulation is intact and not compromised, as damaged insulation can negate the protective qualities of the tool.
