An angle grinder is also known as a side grinder or disc grinder. It is a handheld power tool used for grinding and polishing. An angle grinder is powered by an electric motor, petrol engine, or compressed air. It is standard equipment in metal fabrication shops, on construction sites, auto repair, workshops which comes in a different sizes and motor powers. The story of the inventing angle grinder is not clear. Some say that it was invented by a German company named Ackermann + Schmitt in1954, another says that it was designed in 1973 by a man named Thomas Joseph.
Why should you buy an angle grinder?
Usually, angle grinders are used to cut, grind, polish, sharper, clean, and remove different materials. Different types of wheels or cutting discs are needed according to the material on which it is used.
An angle grinder can replace multiple tools and help to do different jobs, just changing only discs. It is also beneficial to cut materials into different shapes due to its flexible movement.
It is also effortless to use, making it an excellent choice for beginners and professionals. Angle grinder comes in wide variety of shapes and sizes. It is light and precise.
It has many models varying in prices. A buyer should carefully choose which type of angle grinder depending on his/her necessity, usage, and experience. To know more you can browse https://tehno.guru.
Which angle grinder discs do you need?
After buying an angle grinder, the most important thing is to choose which type of blade a user needs. Depending on the materials like metal and masonry, different types of the blade is needed. Blade type will also differ on different types of work like cutting, grinding, stripping, finishing, or all of them. Following are the four basic disk, which are used to operate angle grinder.
Cutting Discs: To cut through metallic items quickly, metallic cutting discs are preferable. Hardness, thickness, and material type will affect the choice of discs. As an example, to cut through stainless steel and copper, different types of discs will be needed. It is always recommended to use higher strength metal discs than the metal which is being cut.
Cutting discs with the sharper grain will require less pressure to cut through the material, making it easy to use the tool.
For cutting metal pipes, thin gauge pipe and tubular workpieces thinner cutting discs with a thickness of 1mm to 1.3 mm is preferable. A thicker disc is needed when a more stable job has to be done.
Grinding Wheels and Flap Discs: To finish a job grinding wheels and flap discs are the most needed accessories for the angle grinder. Grinding wheels use abrasive grains to polish the surface of the situation. These grains act as cutting points. As a result, a grinding wheel has an infinite number of cutting ends, which makes it an excellent accessory for fine finishing tools.
Four types of abrasive grains are available for grinding wheels which are ceramic aluminum oxide (self-sharpening, crisper cutting action), silicon carbide (used for soft metals such as aluminum, cast iron), zirconia alumina (used for high stock removal) and aluminum oxide (used for high tensile material).
Stripping Discs: Many times, people need to remove heavy coating such as paint or rust to use the material again for the same or different purposes. To remove such layers, a coarse grit disc or stripping disc is a need. The amount and rate of removing coating will decide the coarseness of the disc. High coarse grit will remove the coating quickly and will minimize the loading of the disc. But the negative side of using coarse grit is that it will leave a scratch mark on the surface. Rapid strip discs will remove rust without damaging the job or work piece.
Angle grinder discs : It is tough to cut concrete and masonry objects due to its high strength. That’s why specific types of the blade are needed to cut concrete and masonry. A diamond blade is most fitted for these types of jobs as it is a predominantly metallic product, unlike most of the metal wheel.
With a steel center and synthetic diamond at the outer edge, the diamonds act as abrasive material, which gives the blade high rough quality. Due to this high abrasive quality, diamond blades are most ideal for cutting natural stones, concrete, bricks, and building materials.
The angle grinder is one of the best tools for professionals. Its versatile uses make it favorable to any user. But while using it, one must take precautions. Angle grinder produces high heat and residues. To keep him/herself safe, one must always wear protective gear such as gloves, safety glasses, dust masks, and aprons. The user also should always be cautious while operating; otherwise, it can cause severe injuries.
