What are the types of pliers?
Content
Seam pliers split into two primary categories, straight handles/jaws or curved handles/jaws. Among them, there are three more categories: angled, mini-pliers and pliers with replaceable blades.
Straight nose pliers
Straight nose pliers are useful for pre-bending sheet metal at ground level before lifting it up to the roof. Their design helps provide less pressure on the wrist when working in this position.Curved pliers
Pliers with curved jaws or handles are also known as curved, angled, or offset pliers. For easier bending of sheet metal, a larger bending angle will give more force.Curved jaws/handles are useful for bending metal above head height.45 degree angles vs 90 degree angle
Curved pliers have a 45 degree blade….…or a 90 degree blade.The greater the angle of the pliers, the greater the force possible, so when bending metal to a greater angle, you should choose pliers that are bent at an angle of 90 degrees.
Angle pliers
To form a seam at a corner of sheet metal or bend metal at a corner, you can use fillet weld pliers. Using standard pliers for this task is possible, but it will be inconvenient for beginners or casual users who have no practice in metal folding.Angle nose pliers are a specialty tool with slightly rounded blade edges, allowing the pliers to easily go into corners or bend metal at an angle to make a corner.piccolo pliers
Piccolo (small) or mini pliers, so named because they are smaller than any other seaming pliers, are designed for small scale, precision seaming and folding work in tight spaces where wiggle room is limited.Straight piccolo pliers weigh 220 g (0.48 lb), their jaws can vary in width from 20 mm (0.78 in) to 24 mm (0.94 in), the insertion depth is a maximum of 28 mm (1.10 in), and their length is typically from 185 mm . (7.28 inches) up to 250 mm (9.84 inches).
Curved piccolo pliers also weigh 220 g (0.48 lb), have a jaw width of 20 mm (0.78 in), a maximum insertion depth of 28 mm (1.10 in), and a length of 185 mm (7.28 in) to 250 mm (9.84 in). inches). .The curved Piccolo pliers can be used for precise stapling and folding of metal, even at head height.Piccolo pliers are lighter, shorter in length, jaw width and insertion depth than regular size pliers.
