Wonderful!
Flaker Mill: I love it for making your own fresh rolled oats or other grains for oatmeal, granola, or muesli cereals. This is a great flaker! I use it on my Bosch with my 9-grain for cereals and granola. It works so well.

Grain Mill is an inexpensive grinder for hand use that can also be powered. Corn must be run through course, and beans should not be used.

Here it is offered with a hand crank base.
It is also available with an adapter to be motorized by your Bosch, or a motor unit.
