For DIYers and professionals alike, pliers are a versatile, must-have tool for any tool box. Over time, pliers have become designed for specific trades such as electrical, plumbing, HVAC, and more. Whether you’re new to the do-it-yourself lifestyle, or you just want to learn more, lets dive into some crucial plier information.
It’s necessary to understand pliers’ working parts and their duty during use.
Jaws: Plier jaws come in a variety of patterns and designs. The tip of the jaw, known as the nose, can be round, flat, or half-round. Functionalities of the plier jaws can include gripping, bending, and holding objects.
Cutters: Cutters’ intended use is for cutting bolts, wires, nails, and other materials.
Fulcrum (Pivot Point): The fulcrum holds the jaws and handles together, creating leverage and cutting power for the pliers.
Handles: The handles are usually covered by a molded material that helps with grip. There are also insulated handles that help prevent electrical shock.
Pipe Grip: The round, serrated portion of the jaws is called the pipe grip and is ideal for tightening and releasing pipe joins and rounded nuts.
Combination: Combination pliers implement two of the most common uses: cutting and gripping. They are generally used for twisting, bending, and stripping. Combination pliers have a serrated square jaw and are equipped with cutters and a pipe grip.
Combination pliers are commonly called linesman pliers; however, linesman pliers are typically longer than combination pliers to increase leverage, which is necessary for electrical workers.

Slip Joint: Slip joint pliers feature an adjustable fulcrum that allows the jaws, including the pipe grip, to open wider and accommodate the gripped object. Slip joint pliers are mainly used for holding and bending but can also be used for loosening and tightening nuts and bolts.

Tongue and Groove: Tongue and groove pliers have a wide jaw capacity that offers an extensive range of motion for gripping and turning pipes, fasteners, fittings, and more. These pliers can also go by multigrips, groove-joint pliers, or water pump pliers.
Hog Ring: Hog ring pliers clamp hog rings, a metal ring with a split center, together quickly and efficiently. Hog rings are utilized in upholstery, automotive, gardening, and outdoor uses. Hog ring pliers are a popular jewelry plier as bracelets and necklaces are sometimes made using hog rings.

Hose Clamp: Hose clamp pliers are equipped with jaws designed to grip soft hoses to stop the fluid from flowing so the user can work without spillage. They’re also used to remove and replace hose clamps.

Locking: Locking pliers are created to grip an object without assistance from the human hand. Locking pliers, also called vise grips, use an adjustable dial to lock them in place, allowing them to hold the object independently from the user.

Needle Nose: Needle nose pliers have long, tapered jaws that are ideal for use in hard-to-reach areas. These pliers have similar functions to those of combination pliers. Needle nose pliers, also called long nose pliers, are great for bending, holding, placing, and cutting. They have a straight nose or bent nose that has an angle between 45° and 90°. These also make great jewelry pliers, making it easy to bend thin wire and place small objects.

Diagonal: Diagonal pliers usually have a diagonally angled, bladed jaw and longer handles that allow them to cut through steel and copper wires. Diagonal pliers, also referred to as cutter pliers, should never be used to cut through objects thicker than the pliers’ ability or used to cut live wire.

Snap Ring: Snap ring pliers were explicitly invented to make placing snap rings easier. A snap ring is a small metal ring set in a bearing. Typically used in household appliances, vehicles, and generators, the snap ring is installed in parts like grooves and shafts.
Snap ring pliers, regularly known as circlip pliers, come in two types: internal and external. Internal clip pliers’ noses close and the ring is attached to the very narrow tip. External clip pliers widen the snap ring and the handle is gripped.

Crimping: Crimping pliers, often called crimpers or wire crimpers, are crimping tools designed to crimp wires, or small metal objects, creating a firm closure or hold. While these are usually used by professionals who work closely with wire, they’re also fantastic jewelry pliers for crimping beads and closing wire or string ends to keep necklaces and bracelets from unraveling.
