Types-of-Cutting-Tools

Cutting tools have been around since the ancient times, with the first cutting tools used by mankind being made out of stone. Metal became a popular material of choice for manufacturing cutting tools during the Bronze Age 4,700 years ago. By definition, cutting tools refer to any object used to remove unwanted or excess material from a workpiece by means of shear deformation. There are several different types of cutting tools present in the world today, each serving different purposes and application. All types of cutting tools can be classified as either single-point or multi-point cutting tools. Single-point cutting tools such as a scissors are used in turning, shaping or similar operations, whereas multi-points tools include milling, drilling or grinding tools. In order for a cutting tool to operate properly, it must be able to withstand the heat that is generated during the cutting process and be harder as compared to the material being cut. As several different cutting tools cater to various types of cutting needs, the tools should have specific geometry so that they offer clearance angles to prevent the entire cutting tool from coming in contact with the material to be cut, but instead only the cutting edge making contact with the material. There are several factors that manufacturers of cutting tools have to take into consideration when manufacturing cutting tools in order to ensure that the working life of the tool is optimized.

Leather Cutting Tools

Leather cutting tools are essential tools in the industry today, playing a huge role in the manufacture of leather products. As leather is an expensive material, it is important that the tools used to cut leather do not damage it and perform accurate clean cuts. Some examples of leather cutting tools include swivel and utility knives, rotary cutters and shears. Utility knives often have disposable blades which are able to perform deep cuts making them very convenient; even though swivel knives are an ideal choice for carving out the initial outline of a design in leather. This process is important as it would affect the processes following after and therefore should be performed with the care and the right cutting tools. These kind of decorative cuts are referred to as dress cuts and require practice to master. Rotary cutters are used for cutting soft leathers and leather shears are heavy-duty cutting tools used cut lightweight and medium weight leather.

Metal Cutting Tools

As metal is a very hard material, cutting tools required to cut metal have to be very strong. These tools tend to require frequent replacements and sharpening due to wear and tear during the cutting processes. In industrial processes, metal cutting tools such as drills, reamers which create holes with accurate sizes are used, as well as inserts that have two or more cutting edges. In domestic uses, metal cutting tools are smaller and not meant for heavy-duty cutting. Two examples of such tools can be snips and hacksaws. The size of snips ranges between 5 to 14 inches and they do not remove metal during the cutting process, but instead are able to cause small fractures along the edge of the cut. Hacksaws are ideal for cutting metal that saws cannot cut. Some examples include metal pipes and bars.

Glass Cutters

Glass cutters are glass cutting tools that are designed to score glass, thus making it easier to be able to snap a piece of glass in any desired shape and size. Cutting glass can be a very difficult process as glass is very brittle and it is very easy to break the glass, casing potentially dangerous shreds to spread across the work area. Today, there are several different types of glass cutters available in the market to match the requirements of the domestic and industrial users. When cutting glass, the user uses a glass cutter to create a score in the glass. This creates a line of weak in the glass which can be easily snapped off, causing the glass to break. This process makes the job of glass cutting easier and safer, allowing more control of the shape that is formed after the cutting process.
