1) CUTTING DISC:

Cutting discs are made of abrasive materials such as aluminum oxide, silicon carbide, or zirconia alumina, which are bonded together with resin or other materials to form a hard, durable surface. The abrasive material is applied to a reinforced disc that is made of a strong and durable material such as fiberglass or plastic.

The size of the cutting disc can vary depending on the specific application and the tool being used. Common sizes include 4-inch, 4.5-inch, 5-inch, 6-inch, and 7-inch diameter discs. The thickness of the disc can also vary, with thinner discs typically being used for cutting sheet metal and thicker discs being used for cutting thicker materials such as concrete or steel.

The speed of the cutting disc is an important factor to consider when using it for cutting. The maximum safe operating speed is usually printed on the disc itself and should not be exceeded. Exceeding the maximum speed can cause the disc to fail, potentially resulting in injury to the operator.

It is important to select the right type and size of cutting disc for the specific material and application, as using the wrong type of disc can result in damage to the disc, the tool, or the material being worked on. Additionally, it is important to follow proper safety procedures when using cutting discs, including wearing appropriate personal protective equipment such as eye protection and gloves, and ensuring that the tool and disc are properly secured and used at the appropriate speed and angle.

here’s a general size chart for cutting discs:

• 4 inch (100mm) diameter
• 5 inch (115mm) diameter
• 5 inch (125mm) diameter
• 6 inch (150mm) diameter
• 7 inch (180mm) diameter
• 9 inch (230mm) diameter

Note that there may be other sizes available, and the specific sizes offered may depend on the manufacturer and supplier. It’s important to select the appropriate size of cutting disc for the tool being used and the application at hand. Be sure to consult the manufacturer’s recommendations and guidelines before using any cutting disc.

here’s a general thickness chart for cutting discs:

• Ultra-thin cutting discs: 0.8-1.0mm thickness
• Standard cutting discs: 1.2-2.0mm thickness
• Thick cutting discs: 2.0-2.5mm thickness
• Extra-thick cutting discs: 2.5-3.0mm thickness

Note that the specific thicknesses available may vary depending on the manufacturer and supplier. It’s important to select the appropriate thickness of cutting disc for the tool being used and the application at hand. Be sure to consult the manufacturer’s recommendations and guidelines before using any cutting disc.

2) GRINDING DISC:

Grinding discs typically come in two types: depressed center and flat. Depressed center discs have a raised hub and are designed for use with angle grinders, while flat discs are designed for use with bench grinders and other flat-surface grinding machines.

Grinding discs are available in a range of grit sizes, with coarser grits being used for heavy material removal and finer grits for surface finishing and polishing. They are also available in different hardness levels, with harder discs being more durable and longer-lasting but also more prone to causing overheating and discoloration on some materials.

When selecting a grinding disc, it is important to consider the material being worked on, the desired level of material removal or surface finish, and the type of grinder being used. It is also important to follow proper safety precautions when using grinding discs, including wearing appropriate protective equipment and using the disc at the recommended speed and angle.

here’s a size chart for grinding discs:

• 4 inch (100mm) diameter, 6-16mm thickness
• 5 inch (115mm) diameter, 6-16mm thickness
• 5 inch (125mm) diameter, 6-16mm thickness
• 6 inch (150mm) diameter, 6-16mm thickness
• 7 inch (180mm) diameter, 6-16mm thickness
• 9 inch (230mm) diameter, 6-16mm thickness
• 12 inch (300mm) diameter, 6-16mm thickness

Note that the sizes available may vary depending on the manufacturer and supplier. It’s important to select the appropriate size of grinding disc for the tool being used and the application at hand. Be sure to consult the manufacturer’s recommendations and guidelines before using any grinding disc.
