An ID grinder grinds the inside diameter (ID) of a work piece. Usually, this tends to be a longer process than OD grinding as the ID grinding stone is smaller and requires the operator to make smaller cuts to ensure that the ID grind is perfect and to the correct size.

We have 7 I.D. grinders which we can grind from .500 up to 12” internal diameter, 6 through feed and plunge centerless grinders that can grind up to 5” diameter and up to  20 inches in length through feed.
