Wondermill Junior Drill Attachment 

Optional attachment for Wonder Junior Hand Grain Mill 

Turn your Wonder Junior hand mill into a drill powered grain mill with the Drill Bit Attachment. Simply remove the handle, attach the bit to your drill, slide the bit over the end of the shaft, hold it snug, and let the drill do all the work. You will also want to make sure that your Wonder Junior is mounted to something solid that will not move around.

This is a great alternate option to motorizing your hand grain mill. You may already have a heavy-duty drill that will work. If not you can buy a heavy-duty drill and this attachment for much less than a motorizing pulley and a motorizing setup, plus you can use the drill for more than your grain mill.

Recommended Grinding Speeds:

We recommend using a variable speed drill so that you can keep the speed low to prevent prematurely wearing out grain mills and making a mess. We recommend that your speed should not exceed 160 RPM, about twice as fast as you can crank it by hand. 

For Milling Hard Grains (Like Grains & Beans)

The Dewalt DW130V 9 Amp 1/2-inch Heavy Duty Drill works perfectly. It has a low RPM range (0 - 550 RPM), plenty of torque, and plenty of power to handle grinding medium-hard to very hard grains, beans, and dry corn. You can try to use another drill but we know this drill will give you just what you need to power the Wonder Junior hand grain mill.

For Milling Soft Items (Like Nuts & Coffee Beans)

Just about any drill will work for the soft item, even a cordless drill will work for milling very soft items. Keep in mind that some drills are hard to keep the speed at the recommended speed.
