RS PRO Water Pump Plier, 300 mm Overall, 48mm Jaw

The pliers are highly durable thanks to their hardened and tempered metal construction, so they won't break when used for jobs requiring high levels of force. The tool has a serrated jaw that securely grips objects to prevent safety hazards and accidental slippage. You can easily set the tool's pressure using the self-locking mechanism, so you won't need to repeatedly readjust your grip. The slim head lets you reach components in tight spaces, and the soft-grip handle makes it comfortable to use.

You'll commonly find these pliers used by professional plumbers, carpenters and electricians. They're also a good choice for amateur crafters and jewellers.
