Abrasive saws, also known as chop saws or metal cutting saws, are power tools used to cut through hard materials like metal, concrete, and masonry. They have a cutting wheel and motor connected to a pivoting arm mounted on a base plate. Sanding discs differ in size and material of the grit and bonding system. Abrasive saws are portable and can be used in construction sites, but safety precautions must be considered. Eye protection and a respirator should be worn while operating the tool.
An abrasive saw is a power tool used to cut through hard materials, such as metal, concrete or masonry. It can also be called a chop saw or metal cutting saw. The abrasive saw typically has a built-in vise or other type of locking tool. It also has a cutting wheel and motor, both connected to a pivoting arm mounted on a base plate. The abrasive saw cuts with a replaceable abrasive disc, which is typically 14 inches (2.54 cm) in diameter.
Sanding discs, or blades, differ in the size and material of the grit attached to the disc and the material used to attach the grit. Grit types include ceramic, brass, synthetic diamond, and tungsten carbide. Materials used to bond grain include resin, plastic, metal, and electroplated bond systems.
Abrasive saws are lightweight and portable and can be taken to construction sites. As a result, work that previously had to be done in workshops can now be done on site, which has made many construction jobs much easier. Abrasive saws can be used in many construction projects. Some can be used for dry cutting, wet cutting, bench grinding or back grinding. The instrument can also be used in the production of automotive components, ceramics and glass, plastics, electronics and optical products.
Before using an abrasive saw, there are many safety precautions to consider. The user must inspect the saw thoroughly before using it. He or she should also keep in mind that an abrasive saw should never be used in a wet or damp area, due to the risk of electrocution.
If the abrasive saw is supplied with compressed air, the user must ensure that the pressure does not exceed the manufacturer’s recommendations. Higher pressure can create holes in pipes or force the abrasive saw to rotate at an unsafe speed. If the abrasive saw is petrol powered, it should be operated in a well ventilated area so that the operator does not inhale petrol fumes.
The operator must ensure that the saw blade is protected and must never stand in front of an operating tool. When changing the abrasive disc, use should not force the new one onto the tool. The new disc should not be used if it has been dropped or damaged in any way.
Another thing that the user must keep in mind while operating the tool is the risk of aviation hazards. As the abrasive disc wears, it may send its grit into the air. The material being cut may also be blown into the air and injure the eyes and lungs. When using an abrasive saw, the user should always ensure that they are wearing eye protection and a respirator.
