About Us

GrainMaker^® mills are made by Bitterroot Tool & Machine, a custom machine shop in Stevensville, Montana. Our team has more than seventy five years of experience working with metal. We routinely manufacture parts for a custom gun manufacturer, dies used in the aerospace industry, fine tools used by woodworkers and log home builders and other precision machining.

We built the first grain mill for our own use in February of 1999 when we didn't want to wait months to have one delivered from another source. (Y2K was in full swing!) Friends and neighbors soon wanted one in their kitchen; the machine was also well received at shows. After a few modifications, the GrainMaker mill was born.

Owner Randy Jones' passion for solving problems, commitment to precision workmanship and strong faith is evident in everything he does.
