- Do not confuse with 'шлифовальная паста' (grinding/lapping compound), which is for finishing, not cutting.
- The closest equivalent is 'смазочно-охлаждающая жидкость (СОЖ)' or 'паста для нарезки резьбы'.
Common Mistakes
- Using 'cutting compound' to refer to polishing compound (e.g., for cars).
- Treating it as a countable noun (e.g., 'three cutting compounds' is unusual; 'three types of cutting compound' is correct).
- Misspelling as 'cuting compound'.
