A cut-off wheel (also called an abrasive cutting wheel) is manufactured from specialized abrasive grains such as aluminum oxide or silicon carbide, combined with various grit sizes (#10–#4000+), bond strengths, and organic bonding agents. It is primarily used for cutting, slotting, and material sectioning.

The history of metallography dates back to the 19th century, when advancements in metallurgy led scientists to recognize the importance of the internal structure of materials in determining their performance.
