  1. Type: Grinders can be electric, cordless, or pneumatic.
  2. Disc Size: larger the disc, more the power. The most popular sizes are 4½ and 9 inches.
  3. Motor power: The motor powers the disc and is directly responsible for the speed at which work is completed. The rating ranges from 4 to 15 amps. Higher amperage is required for more heavy duty work and also delivers higher performance and efficiency.
  4. Disc Speed: Range is from 5,000 to 11,000 RPM. This is the speed at which the disc rotates and so the speed at which the project is completed. Higher speed machines are also noisier.
  5. Spindle lock: look for simple tool-less versions as these are used to change the discs for various jobs.
  6. Disc Guard: A safety feature, an easy adjust version makes your work faster.
  7. Dust Management: determines the durability of your machine.
  8. Side Handles: preferably select machines which allow for the side handles to be positioned on either side to allow you to maneuver more easily.
  9. Comfort: Look at the dimension especially the barrel size to see if it is comfortable to hold. Also, a lighter machine is easier to handle for longer periods of time.
  10. Safety Features: one of the most important factors while looking at power tools
