What is a screw cutter?

Types of Screw Cutters: Definition, Parts, Uses, Working [with pictures]:-A bolt cutter is also often called a bolt cutter. They are sturdy and portable cutting tools that can easily cut carbide objects such as chains.screw, rods and padlocks. They typically have short blades and long handles.

Screw cutters work

Bolt cutters do not cut through materials like scissors, but rather tear through material by concentrating tremendous forces on the small contact area of ​​the blades. The standard long handles and composite hinges (together add strength to the jaws) work together to give the pliers significant cutting power.

Its cutting power is achieved through a principle known as "leverage", which means that a modest force applied over a long distance (in this case, it's the length of the handles) translates into massive force over a short distance (in cm) is converted in this case to pine).

Uses of screw cutter

Bolt cutters are used extensively in many different areas such as: B. in shipping (to open shipping containers), in agriculture (to work on fences) and in electrical and construction crafts (to cut metal wires and other Construction Materials).

They are particularly used in construction work that requires difficult and repetitive tasks, such as B. Cutting thick steel mesh panels used in RCC.

screw cutting parts

1. Kiefer

The jaws form the head of a pliers and are discreetly forged from the handles. The neck is the part where the blades connect to the handles. They are held in place by a couplescrew🇧🇷 Like scissors connected by a single screw, the compact pliers that carry the blades and the diagonally opposite handle are forged from a single piece.

2. Blades

The blades take over the actual cutting function. They are extremely tough and come in a variety of configurations (eg center cut, shear cut, etc.) to make them suitable for different uses.

3. joints

Most pliers contain multiple gaskets, which are important for tool strength as they multiply the force applied to the handles.

There are three main joints:

  1. The grip pin joint that connects the two handles
  2. The center screw joint that attaches the jaws to the handles
  3. The temporomandibular pin joint that keeps the knives aligned.

All three joints act as pivots when opening and closing the jaws. This composite arrangement helps increase the force the user applies to the tool's handles far more than a single hinge. Jaw pivot pins are subject to high misalignment forces because they allow the jaws to open while keeping them flat.

4. Adjustment screws

Most pliers, with the exception of the compact fixed-head trimmer, consist of one or two adjustment screws in the neck that can change the angle of the blade they are closest to. As two-screw tools, both blades can be adjusted. In addition, the screws on the jaw plates can be turned, which adjusts the gap between the knives.

These are all eccentric screws, meaning they have an irregularly shaped cam-like shank. One of the bolt cutter blades moves when the bolt is turned. Adjusting the jaws with either set of screws will help counterbalance the sharpening, or you can adjust the screw cutter so it can hold thicker pieces of material in place.

5. Claw

Bolt cutter handles vary in length and the material they are made of. This makes a significant difference in its weight and ease of use. Longer lengths are very useful for cutting materials that go deep/upwards, are out of reach or require significant effort, while short pairs are lightweight and useful for roughing out materials that are easy to reach.

6. Adhesion stops

Long handled regular bolt cutters usually have a pair of metal stops at the neck or slightly down the handles. This prevents the handles and blades from moving too closely together and breaking at the end of a cut.

7. Handshakes

For added convenience and tool control, most long-handled pliers have rubber grips on the end of the handles.

Types of screw cutters

In most cases, the shape of the blade determines the type of pliers. Below are the types of screw cutters:

  1. Center Cut Screw Cutters
  2. Clipper Cut screw cutters
  3. angle screw cutters
  4. Bolt cutters with a shear cut
  5. End Cut Screw Cutters
  6. ratchet screw cutters
  7. compact screw cutter
  8. manual screw cutter
  9. hydraulic screw cutter

1. Center Cut Screw Cutters: ( Types of Screw Cutters )

Bolt cutters with center cutting blades are very popular and versatile. They are effective because the blade's four beveled edges (the double bevel on each blade) apply an even force to the material being cut, eventually asserting itself on both sides of the item. They are best suited for a variety of jobs such as: B. cutting poles, thick cables and pipes.

2. Clipper Cut Screw Cutters: ( Types of Screw Cutters )

With this type of cutting edge, the upper surfaces of both blades are chamfered towards the flat sides of the jaws. The lower edges of the blades create a distinctly thin edge that allows the tool to apply just as much pressure as its center-cut counterpart. This means that when the tool is flat, the cutting edge is close to the surface, making serrated blades ideal for cutting protruding nails, dowels or screws close to the surface of a workpiece.

3. Angled Screw Cutters: ( Types of Screw Cutters )

If the bolt cutter head is angled and does not have a flat plate underneath, the blades can cut even deeper. This type of tool can cut screws or nails almost to the surface they penetrate.

For cutting things like nails sticking out of boards, an angled head screw cutter often comes in handy. This raises the handle from the surface being worked at a 20 or 30 degree angle to the head, leaving enough room underneath for one hand to hold the tool.

4. Shear cutting cutting pliers: ( Types of Screw Cutters )

Scissor Cut Bolt Cutters are the ideal tool for cutting wire rope. Rather than having the blades pressed against each other, the scissors blades are designed to overlap and slide.

These tools are commonly used for cutting rope, which they can cleanly and accurately do by cutting rather than slicing. The hooked shape of the jaws helps keep the handle in place during the cutting process.

5. Final Cut cutting pliers: ( Types of Screw Cutters )

The end-cut screw cutter jaws consist of flattened blade ends. The flattened blade is turned inward to form a forceps head. They are used to grab material and then break it down, e.g. B. Screw heads that are in a narrow place that is difficult to reach and with other similar cutting heads. B. Center cutter or cutter heads cannot be approximated.

6. Ratchet Bolt Cutter: ( Types of Screw Cutters )

Bolt cutters with ratchet hinges that allow the user to apply pressure in short bursts instead of applying force over a long period of time. These are generally more expensive than pliers without this feature.

7. Compact screw cutter: ( Types of Screw Cutters )

Bolt cutters are called compact bolt cutters when they have handles that are around 200m long (or less, although this is the minimum commonly used size). This type of tool is designed for lighter jobs, such as B. cutting fence wire or fine locks. They are lighter than standard pliers and are ideal for home and garden use.

8. Manual screw cutter: ( Types of Screw Cutters )

Hand screw cutters have a wide range of uses. There are several styles and sizes of pliers to suit most household jobs. They are also used in construction. However, when the cutting task was difficult and dangerous, construction workers as well as rescue workers switched to a power tool.

9. Hydraulic bolt cutter: ( Types of Screw Cutters )

Hydraulic bolt cutters have powerful battery-powered motors and are generally cordless and easy to use. The jaws of hydraulic bolt cutters work primarily like a guillotine, with a flat blade or blades forcefully cutting through the material to be cut.
