types of pliers and how to use
Over the centuries, pliers have become essential in industries like construction, electrical work, plumbing, automotive repair, and even delicate crafts such as jewelry making. They are tools that both DIYers and professionals rely on for a wide range of tasks.
Pliers can grip, tighten, loosen, bend, and cut materials, making them useful for everything from fixing a bicycle to wiring repairs or detailed craftwork. Since no single type suits every job, most tool users keep several kinds in their toolbox.
This article explores common pliers like slip-joint, lineman’s, locking, and needle-nose, as well as specialty tools such as welding, oil filter, and fencing pliers. By understanding pliers differences and applications, you can choose the right tool for the job and work more efficiently and safely. Let’s dive into the world of pliers and see how this simple yet powerful tool can make all the difference.
What are pliers and how do they work?
Pliers are handheld tools designed for gripping, holding, bending, cutting, and shaping materials. They are used in everything from household repairs to specialized work in construction, electrical projects, plumbing, and crafts. Their value comes from the way they amplify hand strength, allowing users to grip and manipulate objects with far greater precision and control than with bare hands.
Basic design of pliers
At their core, pliers have a simple yet highly effective design. Knowing their main parts helps explain how they work and why they are so versatile. Most pliers share the same basic components:
- Handles: The handles are the parts you grip and squeeze to operate the pliers. They are usually coated with rubber, plastic, or vinyl to provide comfort, reduce slipping, and minimize fatigue during extended use. In specialized pliers, especially for electrical work, handles may be insulated to protect users from electric shocks when working with live wires.
- Jaws: The jaws are the working end of the pliers, designed to grip, bend, or cut materials. They may be flat, curved, serrated, or shaped for specific purposes. In cutting pliers, the jaws feature sharp blades for snipping wire, nails, or other materials. This versatility makes pliers a go-to tool for both professionals and diy users.
- Pivot point: The pivot point is the joint that connects the two arms of the pliers. It allows the handles to move in opposite directions to the jaws, multiplying the force applied by the user. This leverage makes it easier to grip or cut tougher materials.
- Teeth: Teeth are the textured sections inside the jaws that provide extra grip. They may be serrated, angled, or cross-hatched, depending on the pliers’ purpose. While useful for holding objects firmly, the teeth of certain pliers—such as locking pliers—can leave marks or damage on softer surfaces.
- Cutters: Many pliers also include cutting edges located near the pivot point. These sharp blades allow the user to slice through wire or other thin materials with ease. Not all pliers have cutters, but they are common in multi-purpose designs.
Different types of pliers and their uses
Pliers come in many shapes and sizes, each designed for specific tasks. Knowing their differences ensures you always choose the right tool for the job. Below are some of the most common types:
Slip-joint pliers
Slip-joint pliers feature an adjustable pivot point that allows the jaws to open wider, making them versatile for gripping objects of different sizes.
Commonly used for general gripping, bending, and holding in household repairs, plumbing, and light mechanical tasks. Their jaws typically combine flat serrations for gripping flat objects and curved sections for holding round items like pipes or rods. Many also include small wire cutters near the pivot for added utility.
Crimping pliers
These pliers have notched jaws designed to crimp electrical connectors onto wires. Some models come with interchangeable dies for different connector sizes and shapes.
Essential in electrical and networking work, crimping pliers secure terminals to wires, allowing reliable electrical connections. They work with a range of wire sizes and are a must-have for electricians and network technicians.
Needle-nose pliers
Characterized by their long, tapered jaws, needle-nose pliers allow access to tight or confined spaces. Some models feature angled tips (45° or 90°) for greater versatility.
Perfect for precision tasks like electrical work, jewelry making, and handling small components. They are excellent for bending wire, holding fittings, or retrieving tiny objects. Many also include side cutters near the pivot for cutting wire. However, they are not intended for heavy-duty applications, as the thin jaws can bend or break under excessive force.
Lineman’s pliers
Lineman’s pliers have thick, sturdy jaws with a gripping surface and built-in cutting edges.
Essential for electricians, they are used for twisting wires, cutting cables, and gripping materials securely. Their shallow serrations provide a firm grip on flat objects like sheet metal, while the cutting blades just behind the jaws handle wire with ease. Typically available in sizes from 5 to 10 inches, the 8-inch model is the most common. Though sometimes called electrician’s pliers, they should never be used on live wires—always ensure power is disconnected before working.
Cutting pliers (diagonal pliers)
Also known as diagonal cutters, these pliers have angled jaws with beveled cutting edges designed for clean cuts.
Primarily used for snipping wires, trimming nails, and cutting small metal parts. They are common in electrical and mechanical work, capable of cutting materials like electrical wire, braided cable, wire ties, and nylon straps. Unlike other pliers, diagonal cutters are designed solely for cutting and not for gripping or turning objects.
Locking pliers (vise-grips)
Locking pliers feature an adjustable screw and lever mechanism that allows the jaws to clamp tightly and stay locked in place until released.
Ideal for holding objects securely, loosening stuck bolts, or clamping materials during repairs. Their compound lever action gives them a powerful grip, acting like a portable vise. Available in various jaw styles—straight, curved, smooth, or long-nose—as well as c-clamp versions, locking pliers are versatile replacements for wrenches, pipe wrenches, or clamps in many applications.
Combination pliers
Combination pliers feature a gripping surface at the tip, cutting edges near the pivot, and a flat section for bending.
A versatile all-purpose tool, they are ideal for gripping, twisting, cutting, and light crimping. Common in construction and electrical work, they can handle general repair and assembly tasks. While similar to lineman’s pliers, they are lighter and not intended for heavy-duty cutting of thick wires or metal.
Snap ring pliers (circlip pliers)
These pliers have pointed tips designed to fit into the holes or grooves of snap rings (circlips), allowing the user to open or close them safely.
Essential for mechanical work involving bearings, gears, and shafts, they prevent snap rings from slipping or flying away during installation or removal. Widely used in appliances, hose fittings, and valve repairs, they make handling springy retaining clips far more controlled and efficient.
Hose clamp pliers
Equipped with rotating jaws and often a locking lever, hose clamp pliers make it easier to grip and secure spring-style hose clamps from different angles.
Commonly used in automotive repair for radiator hoses, they are also useful in plumbing for pools, spas, sump pumps, and similar equipment. Their locking feature helps hold clamps in place during installation or removal.
Bent-nose pliers
Similar to needle-nose pliers but with curved jaws instead of straight ones. They feature tapered tips for precision and often include cutting edges near the pivot for cutting and stripping wire.
Ideal for working in tight or awkward spaces where straight jaws would block visibility. They are useful for bending wire, making electrical connections, picking up small items, and reaching confined areas more easily than standard needle-nose pliers.
Water pump pliers
Also known as arc-joint pliers, channel-lock pliers, or simply “pumps,” these have long handles and adjustable, serrated jaws that can grip objects of varying sizes. Their angled jaw design makes it easier to reach into tight or awkward spots, while the extended handles provide added leverage.
Commonly used for gripping and turning pipes, fittings, and other large objects. Although often associated with plumbing, they are also handy in automotive, mechanical, and general repair work. Available in sizes from 4 to 16 inches, medium-sized models are the most versatile for everyday use.
Bell-making pliers
Feature cylindrical jaws of varying diameters that allow users to wrap wire around them to create coils.
Primarily used in jewelry making and crafts for forming decorative wire loops and coils.
Battery pliers
Square-shaped, slightly angled jaws with serrations for a strong grip on battery terminal bolts. Non-adjustable, since most terminals are a standard size.
Designed for removing and tightening square battery terminal bolts in vehicles, lawn equipment, and motorcycles without stripping them.
Flat-nose pliers
Similar to needle-nose pliers but with flat, squared tips for added durability and a broader grip surface.
Common in jewelry making for bending wire and holding small parts. Also useful for gripping snap rings and clips in tight spaces.
Ironworker’s pliers
Longer, heavier jaws and hooked handles for extra leverage, with shock-absorbing grips on some models.
Built for twisting and cutting tough rebar wire, making them sturdier than standard lineman’s pliers.
Wire-twisting pliers
Look similar to lineman’s pliers but with a built-in twisting mechanism. The jaws lock on the wire ends, and a pull-knob twists the wire automatically.
Ideal for evenly twisting wire ties in construction, fencing, and rebar work.
Nail-pulling pliers
Serrated jaws for gripping nail shanks and a curved pivot surface for leverage. Some models include cutting jaws for nail removal.
Best for pulling nails through wood without damaging the surface, useful in restoration and remodeling projects.
Oil filter pliers
Long, curved jaws with teeth for gripping slippery oil filters, often with adjustable openings to fit different filter sizes.
Simplify removal of greasy oil filters in cars, tractors, and other machinery.
Welding pliers
