Drill Bit Attachment

Turn your WonderMill Jr Deluxe hand mill into a power mill.


Simply remove the handle, attach the bit to your drill, slide bit over the end of the shaft, hold it snug, and let the drill do all the work.

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 mill and making a mess. Your recommend that your speed should not exceed 160 RPM, about twice as fast as you can crank it by hand.

Drill Recommendations:

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 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.
