§ Hard material can be easily machined by this method.
§ No heat generated in work so there is no problem of work hardening or change in structure of work piece.
§ Non-conductive metals or non-metals, which cannot be machined by ECM of EDM can be machined by it.
§ It does not form chips of significant size.
§ It is quite slower than other mechanical process.
§ Tool wear is high because abrasive particle affect both work-piece and tool.
§ It can machine only hard material. Ductile metal cannot be machine by this method.
§ It cannot used to drill deep hole.
