I am just bought a milwaukee 5615 router and looking to buy an
aluminum router table plate from Rockler

Someone told me that the Milwaukee has the same mounting holes as the
porter cable routers but the guy at Rockler said I souldnt buy a
predrilled and should drill my own.

Does this router share the mounting holes with porter cable or anyone
elses router?

Milwaukee sells a edge guide that works with a bunch of milwaukee
routers and "most industry standrd" routers so I assume if its edge
guide works with someone elses router there should be a router plate
that works with the milwaukee router.
