Pliers are among the most useful hand tools in a garage, but choosing the wrong pair can make a simple repair frustrating. Different types of pliers have different jaws, cutting edges, and gripping mechanisms, each designed for particular jobs.
Whether you’re replacing a radiator hose clamp, working on electrical connectors, removing a retaining ring, or gripping small metal components, understanding the different kinds of pliers helps you work more efficiently.
In this updated guide, we’ll explain 16 common and specialized pliers types, how to identify them, what each is used for, and which ones are most valuable for automotive repairs.
What Are Pliers and What Are They Used For?
Pliers are manually operated tools that typically feature two handles connected at a pivot, with jaws or cutting edges at the opposite end. Squeezing the handles moves the jaws together to grip or manipulate a workpiece.
Their usefulness comes from leverage and jaw design. Long, narrow jaws can reach confined spaces, serrated jaws grip suitable objects, and dedicated cutting edges separate appropriate materials.
Main Parts of Pliers
Jaws
The working ends that grip, hold, compress, or manipulate suitable materials.
Pivot Joint
Connects the handles and transfers force to the jaws.
Handles
Provide leverage, control, and a comfortable gripping surface.
Cutting Edges
Present on certain models for cutting suitable wires or other approved materials.
What Jobs Can Pliers Perform?
- Grip or hold small metal parts.
- Bend suitable wire and light-gauge materials.
- Cut wire, cable ties, or specified materials.
- Operate compatible hose clamps.
- Remove and install retaining rings.
- Crimp compatible electrical terminals.
- Hold parts temporarily during assembly.
