Hager,
You get different types of reamers. You get adjustable reamers,
parallel shank reamers that can be held in a drill chuck (preferably in a collet) and tapered (morse taper) shank reamers.
A H7 tolerance means a clearance larger than the dia of the hole.
You can ask your tool suplier for charts on tapping & drilling sizes as well as technical info on tolerances regarding reaming.
