Metal hand cutting shears

Types of metal hand cutting shears

Metal hand cutting shears are tools for cutting metal sheets or wires. They have two blades that pivot together like scissors. The handles are usually covered with rubber to help grip the tool. The tool cuts metal by bringing the two blades close together and squeezing the metal between them. The metal is then cut by the sharp edges of the blades. The blades may be straight or angled, depending on the type of shear.

Metal hand cutting shears come in different types. Each type has a specific function when it comes to cutting metal. They include:

• Straight cutting shears: These are the most common type of metal cutting shears. They have straight blades and are used for making long, straight cuts in thin metal sheets. They are best suited for cutting sheet metal, ductwork, and other metal fabrication projects.
• Notching shears: Notching shears have curved blades that cut metal sheets in notches. The tool cuts the metal in small U-shaped notches. These shears create small cutouts or notches in metal sheets to allow for bending, folding, or fitting metal pieces together.
• Circular cutting shears: These are used for cutting circles or arcs out of metal sheets. They are ideal for creating circular cutouts, such as holes for pipes or vents.
• Compound cutting shears: These shears have a unique design that uses two pairs of handles to create more cutting power. This makes them ideal for cutting thicker metal sheets or bolts. They have a ratcheting mechanism that increases the cutting force, making them suitable for cutting thicker materials.
• Power shear: These are heavy-duty cutting tools powered by electricity or compressed air. They have blades that move back and forth or in a circular motion. The tool is suitable for cutting large metal sheets and are commonly used in industrial settings.

In summary, choosing the right metal shear for the job depends on the thickness and type of metal being cut and the desired cutting precision.

How to choose metal hand cutting shears

When choosing metal hand cutting shears, it is essential to consider the type of metal being cut, the thickness of the metal, and the frequency of use. For thin metal sheets, lightweight shears with straight blades may be sufficient. For thicker metal, heavier-duty shears with curved blades may be needed. If the metal is being cut frequently, it is essential to choose a shear that is comfortable to use and has a larger cutting capacity.

• Consider the type of metal:

  Shears are designed for different types of metal, such as aluminum, steel, or copper. Choosing a shear specifically designed for the type of metal being cut is essential to ensure a clean, precise cut and to avoid damaging the shear blades.

• Cutting capacity:

  Consider the thickness of the metal sheets that need to be cut and choose a shear with a suitable cutting capacity. Some shears can cut through thicker metal, while others are only suitable for thin sheets.

• Frequency of use:

  If the shears are being used frequently, it is essential to choose a shear that is comfortable to use and has a larger cutting capacity. This is because frequent use requires more comfortable shears to avoid hand fatigue and have a larger cutting capacity to handle the metal's thickness.

• Blade material:

  Look for shears with blades made of high-quality steel or other durable materials that can withstand wear and tear. The blade material affects the shear's cutting performance, longevity, and maintenance requirements.

• Cutting edge:

  The shape and sharpness of the cutting edge can impact the quality of the cut and the ease of use. Look for shears with a sharp cutting edge and a shape that is suitable for the type of metal being cut.

• Handle design:

  The handle design can affect the comfort and control of the shear. Look for handles that are ergonomic and provide a comfortable grip, as well as a design that allows for better control when cutting.

• Weight and balance:

  The weight and balance of the shear can impact the ease of use and the quality of the cut. Look for shears that are balanced and easy to use with one hand, as well as a weight that is suitable for the type of metal being cut.

How to use and product safety

While hand shears are an important tool in any gardener's arsenal, they must be used carefully to avoid injury to oneself or others. Always ensure that the cutting blades are sharp and clean before use, as blunt blades require more force and can slip off the intended cutting point. When cutting, make sure to cut only what the shears are rated for, as trying to cut thicker branches can damage the tool and potentially cause it to snap back towards the user. Always cut with the hand that is not holding the shear behind the cutting point to avoid injury.

It is also important to maintain a firm grip on the shears and to cut in a controlled manner to avoid accidents. After use, it is important to store the shears safely, with the blades closed to avoid any accidental cuts. Additionally, regular maintenance such as oiling the pivot point and tightening any loose screws will ensure the longevity and efficiency of the tool.
