Rock mills are a drum cutter fitted with replacable hardened cutters. These are used for cutting trenches and tunnelling or for profiling rock faces, such as cutting to profile rockfaces.

Some quarries are using them for ripping softer rock up were blasting is not allowed, instead of ripping with a large Bulldozer An advantage is the smaller size of the materail produced removes the need for a primary crusher and in some cases, just needs screening, resulting in production cost advantages.
