Frequently Asked Questions (FAQs)

1. Why are 9 inch grinders banned?

9 inch grinders have been banned from many work sites due to the increased risk of injury. Workers often remove guards and use incorrect discs, which significantly raises the level of risk. This has led to catastrophic injuries and fatalities, prompting the ban.

2. What is a 9 inch angle grinder used for?

A 9 inch angle grinder is not limited to metal cutting. It can also be used for small-scale work with tile, masonry, and stone. With a steady hand, it can be an effective alternative to tile saws or cut-off saws. Typically, abrasive or diamond wheels are used for cutting these materials.

3. How deep will a 9 inch angle grinder cut?

A 9 inch angle grinder can provide a cutting depth of about 3 inches. This means that when cutting from one side only, both sides of the wall or material being cut will have debris and dust ankle-deep.

4. Will a 9 inch grinder cut through a brick?

Yes, a 9 inch angle grinder is capable of cutting through larger brick sizes. While smaller size bricks can be cut with a 4-inch or 6-inch grinder, the 9-inch grinder is more suitable for cutting larger brick sizes.

The most common size of an angle grinder is the 4.5-inch grinder. It uses wheel discs that are 4.5 inches in diameter. However, larger sizes are also available, such as the 7-inch grinder, which uses a 7-inch disc. It's important to note that the larger sizes use larger wheels.

6. What Cannot be cut with an angle grinder?

Angle grinders are not suitable for cutting aluminum and brass. The wheel's surface quickly fills with swarf when cutting these materials, making it ineffective. If needed, it is recommended to have a good layer of nonferrous material over the steel to slow down the cutting process.
