making and accurate hole size


Jul 29, 2003
I am trying to fit a 0.8750" O.D. bearing in a plate of aluminum, and the hole saw I have is naturally not accurate enough. I am thinking of using a hole reamer after cutting with the hole saw, because i have read these have an accuracy of less then a thousandths. This needs to get done before ill have access to a mill, so do you guys have any ideas? My questions on reaming a hole are: 1) if the hole is 0.860" will the reamer be able to take that much off, 2) use a chuck reamer or a hand reamer? 3) is there a better way to get the bearing in the plate? the bearing will not support much load, so thats not an issue, its mostly have a snug fit to eliminate play yet not bind up the bearing.
