How to Use Diagonal Pliers?

The diagonal pliers, serve a versatile purpose and are indispensable tools in both daily life and work. These diagonal pliers are equipped with a blade that can effectively cut through rubber or plastic insulation on flexible wires. Additionally, the knife-edge of the pliers is suitable for cutting wires and iron wires. When dealing with No. 8 galvanized iron wire, simply employ a back-and-forth cutting motion with the knife on the surface a few times, and then apply a slight pulling force to break the wire. Furthermore, diagonal pliers can also be utilized to cut hard metal wires like electric wires and steel wires. Electricians typically possess diagonal pliers with various specifications, such as 150mm, 175mm, 200mm, and 250mm, which can be purchased based on the requirements of internal or external work types. The pliers' teeth can also be employed to tighten or loosen nuts.

To provide a comprehensive understanding of diagonal pliers, let's delve into their different types and functions, as well as their correct usage. This information will enable you to enhance your knowledge and familiarity with diagonal pliers. Below, the diagonal pliers manufacturer presents the primary categories, functions of diagonal pliers and correct way to use.

The classification of diagonal pliers

Diagonal pliers, also known as oblique nose pliers, are available in various categories and sizes. Oblique nose pliers are classified as professional electronic oblique nose pliers, German energy-saving oblique nose pliers, stainless steel electronic oblique nose pliers, VDE high pressure resistant large end oblique nose pliers, Nickel-iron Alloy European oblique nose pliers, refined American oblique nose pliers, energy-saving oblique nose pliers and so on.  

In addition to the various categories, the market offers diagonal pliers in different sizes. The most common sizes include 4", 5", 6", 7", and 8". Sizes larger than 8" are relatively uncommon, while smaller sizes, such as mini diagonal pliers, are typically around 125mm. 

When selecting the size of diagonal pliers, consider the following suggestions: The primary function of diagonal pliers is to cut wires. However, it is not recommended to use them for cutting single strands of copper wire or iron wire with a cross-sectional area of 2.5mm² or above, as this can cause damage to the pliers. For general electrical wiring tasks, 6" and 7" pliers provide sufficient cutting ability with minimal effort. For circuit board installation and maintenance, 5" and 6" pliers are commonly used due to their flexibility and reduced fatigue during prolonged use. The 4" size is suitable for small jobs.

Note: It is important to use diagonal pliers within your strength capacity and avoid using them to cut steel wire or excessively thick copper wire, as this can lead to damage or tooth collapse.
 

Diagonal Cutting Pliers function:

Diagonal cutting pliers are also called flat cutting pliers or bolt cutters. The specifications of diagonal pliers are the same as the needle-nosed pliers. 160mm flat pliers with insulated handles are most commonly used. Some flat pliers add springs between the two grips to reduce hand fatigue and make it more convenient to use.

Use of diagonal cutting pliers:
 

Diagonal pliers are primarily used for cutting wires and removing excess leads from components. They are also commonly used as a replacement for general scissors when cutting insulated bushings and nylon tie wire cards.

The cutting edges of diagonal pliers are effective in cutting the rubber or plastic insulation of flexible wires. They can also cut all types of wires: soft wires and hard metal wires such as steel wire, etc.

The use of diagonal pliers step by step:

1.Make sure the space where you'll be performing the cutting task is properly arranged, clearing away any obstructions that may hinder your access to the material you intend to cut. 

2. Prioritize your safety by wearing protective gloves, goggles, and a long sleeve shirt, as these precautions significantly reduce the risk of being harmed by any potential flying fragments or debris.

3. To open the jaws, simply pull the handles in opposite directions.

4. If you're dealing with hard wires, position the wire as close to the base of the blades as you can to maximize leverage and cutting power. 

5. For softer wires, it's more effective to place them closer to the tip of the blades. Once you have the wire in position, firmly squeeze the handles together until you achieve a clean and precise cut.

Electricians often use diagonal pliers with specifications like 150mm, 175mm, 200mm, and 250mm, selecting the appropriate size based on their specific internal or external work needs. Additionally, the jaws of the pliers can be used to tighten or loosen nuts.

The correct way to use diagonal pliers involves two grip methods: palm-down grip and palm-up grip. In the palm-down grip, the diagonal pliers are held with the right hand, using the thumb and other four fingers to grasp the handle, allowing the pliers' blades to face forward for cutting with force. The palm-up grip applies the same force as the palm-down grip, but the pliers are held in an upward-facing position.

When using diagonal pliers, it is important to ensure that the pliers face downward to prevent injury from the cut wire. Avoid using flat jaw pliers to cut thick steel wire, screws, and other hard objects to prevent damage to the jaws. It is strictly prohibited to cut live wires with damaged plastic covers using flat jaw pliers to avoid electric shock and ensure personal safety.

Users of tools must be familiar with the performance, characteristics, usage, storage, repair, and maintenance methods of the tools they handle. When using pliers, maintain a right-handed grip, turn the pliers' jaws inward to control the cutting action, place the little finger between the two grips to press against them, and open the head of the pliers to allow for flexible separation of the grips.
