Plier, Combination

Quick Answer: A combination plier is a general-purpose hand tool whose jaws combine flat serrated gripping faces at the tip, a curved pipe grip in the middle and a pair of cutters near the pivot. The combination plier grips, bends, twists and cuts wire in electrical and workshop tasks.

Three Zones in One Jaw

Each part of the jaw has its own job. The flat tip holds sheet, flat bar and the ends of wires for bending into hooks and loops. The rounded, serrated recess behind it grips round rod, small pipes and nuts. The cutters near the pivot shear copper and other soft wire, and because they sit close to the pivot they get the most leverage from the handles.

In physics and electrical practicals this plier twists conductors together, bends connecting leads to fit terminals and trims wire to length when circuits are built. It is also known as a linesman’s plier. The handles on many models carry plastic sleeves; unless the plier is clearly marked and rated as insulated for live work, those sleeves are only for grip, and circuits must be switched off and isolated first.

It covers many jobs moderately well. For fine electronics a long nose plier reaches smaller spaces, and a side cutting plier makes cleaner, closer cuts on component leads. The length of this model can be confirmed with LabEquip.

Applications

• Twisting and joining conductors in electrical wiring practicals
• Bending connecting wire to fit terminals, crocodile clips and binding posts
• Cutting copper wire to length for coils, circuits and models
• Gripping nuts, small rods and sheet in general workshop tasks

Specifications

Care & Handling

• Cut wire at right angles to the edges, close to the pivot, without rocking the plier.
• Do not use the plier as a hammer or on hardened wire, which nicks the cutters.
• Keep the joint lightly oiled and free of grit.
• Discard any plier whose rated insulation is cracked or damaged.

Why Choose LabEquip

Physics and electrical laboratories, wiring and electrician courses and general workshops buy combination pliers in quantity for student benches. LabEquip supplies them from its General Lab Products range; ask about insulated versions through the contact page.

Frequently Asked Questions

What is a combination plier used for?

Gripping, bending and twisting wire and small parts with the jaws, and cutting soft wire with the edges near the pivot. It is the most general of the plier types and is often the first one added to a toolkit.

Are the handle grips insulated for electrical work?

Only if the plier is clearly marked and rated for live work. Ordinary plastic sleeves improve grip but do not protect against shock, so circuits should be isolated before any work.

How does it differ from a side cutting plier?

A combination plier grips and cuts, with its cutters near the pivot. A side cutting plier is only for cutting, and its edges are shaped to cut closer to a surface, which suits trimming component leads.

Can it cut steel wire?

Thin soft iron binding wire, yes. Hard steel wire such as spring or piano wire can chip the edges and is better cut with a tool made for hard wire.

How do I twist two wires together neatly?

Strip the ends, lay them side by side, grip both at the tips of the jaws and twist the plier clockwise several turns, keeping gentle tension. Trim the end square and cover the joint as required.

Why do the jaws no longer close fully?

The joint may be dirty or bent from use as a lever, or the cutters may be damaged. Clean and oil the pivot, and replace a plier whose jaws are misaligned.
