What Can Angle Grinders Do?
Angle grinders use different kinds of discs for various jobs. Imagine needing to cut metal, smooth a rough edge, or even clean rust. An angle grinder can do all these things with the right disc.
Types of Discs
- Grinding stones: These are used to smooth rough surfaces or remove extra material.
- Sanding discs: These help to make surfaces very smooth, like sandpaper.
- Wire brush wheels: These are good for cleaning rust or old paint from metal.
- Cut-off discs: These thin discs are used for cutting through metal or other hard materials.
- Polishing pads: These make surfaces shiny and smooth.
Different Sizes and Power
Angle grinders come in many sizes. They have different disc sizes and motor strengths. Some run on batteries, others plug in. Some are powered by air (these are called pneumatic). The speed of the disc is measured in RPM. This tells you how fast the disc spins.
Generally, bigger discs mean more power. Small, air-powered grinders are often used for jobs that need more care and precision. Larger electric grinders are usually chosen for bigger, tougher jobs.
Staying Safe with Angle Grinders
Angle grinders are powerful tools, so safety is very important. When they cut metal, they can create many sparks. Sometimes, the cutting blades can even break during use.
Always wear the right safety gear when using an angle grinder. This includes safety glasses, gloves, and hearing protection. Never use an angle grinder without its safety guard. This guard helps protect you from sparks and broken discs. Also, always make sure the handle is attached. Before you start, always check the disc for any cracks, damage, or too much wear.
