WHAT DRILL FOR THIS BEARING INSTALL????

[riversidedan]

ok guys am doing a project that entails a bearing install at both ends of this 5 in. bar, being the bearing is flat am assuming a flat end bottom mill type drill would work, would that be right?? never using one would also assume I would plunge it into the work, right??

If these bearings are gonna be in any kind of alignment you are not gonna what to drill the hole to final dimension. A drilled hole will be oversized and finish wouldn’t be good for a bearing bore.
If I was gonna do it I would drill a hole undersized to the bearing. Then depending on the bearing size I would use a endmill which has a flat bottom and are on size. Better yet would be to use a boring head.
