All of our grinders give you the same uniformity and consistency over the entire range of settings. The main difference is in the speed of the grinding.
If you need a coffee grinder and volume and speed are not an issue, our 804 series grinders would get you started with a quality grinder to satisfy any application. The main deciding factory is what you will be grinding into - for coffee bags and filters, the KR804 with the vibrator plate is your best choice for low volume grinding. For grinding into filters or cans, the modified KR804 is your best choice.
