Single-end chamfer mills with a straight shank have angled cutting edges on one end for creating chamfered or beveled edges on a workpiece. They are less fragile than double-end chamfer mills. The chamfer mills' straight shank installs into a chuck, collet, or heat-shrink toolholder on a milling machine.

Double-end chamfer mills with a straight shank have angled cutting edges on both their ends for creating chamfered or beveled edges on a workpiece. They can accomplish more milling tasks than single-end chamfer mills before they need to be replaced. When the cutting edges on one end wear down, the end mill can be flipped over to expose the fresh cutting edges on the other end. These end mills have a straight shank that installs into a chuck, collet, or heat-shrink toolholder on a milling machine.
