Primary and Secondary
Relief Grinding
Cutting edges are typically “relieved” to enhance chip
clearance. Primary relief involves removing material
directly behind the cutting edge. For secondary relief,
a slight bevel is ground next to the primary relief.
The wheels listed in this catalog are in stock and intended as a
general starting point for the application indicated. These wheels
are recommended for wet applications. For dry applications or
