This extralarge food mill has another element that makes it best for jams and jellies: the way it scrapes food as it mills. The innovative scraper works automatically as you turn the handle, so you get the smoothest, most continuous flow. The mill features nonslip handles and comes with three different disc sizes.

Imagine the angle between the edge of the helix (the spiral flute) and the flat bottom of a standard endmill. A low helix endmill has an angle of 35 degrees or less whereas a high helix endmill has more than 35 degrees. A good roughing + finishing in one cutter compromise is a 38 degree helix angle.
