Facts About Belt Sanders
• Start before setting down.
• Make sure you keep flat on the surface. It is an aggressive tool and with any sort of tilt, it will create a groove.
• Follow the grain.
• A belt sander is great for tough jobs on flat surfaces. It can remove a lot of material quickly and is good for larger projects.
Facts About Finish Sanders
• Good for materials that only require higher grit, light sanding.
• Oscillates back and forth, so it can get into tight corners.
• Slower and gentler than most sanders. Therefore, any large areas will be very time-consuming.
Facts About Random Orbit Sanders
• Good middle ground between a belt sander and a finish sander.
• Rotates in a circle at varying speeds, hence “random”.
• Works fast and can get a lot of material off.
• It is the best kind of sander to work through a variety of grits.
