If you are on a tight budget but still want the benefits of fresh ground coffee, blade grinders are a great option. Blade grinders feature a sharp metal blade that spins with extreme speed to crush the coffee beans. The duration of the grinding determines the coarsness of the grounds.
Blade grinders work best with drip coffee makers that utilize a paper filter that will prevent uneven grinds from finding their way into your cup.
