# Water Jet Water jets use high-pressure streams of water—sometimes mixed with abrasive substances—to cut hard materials like metal or granite. This method is ideal for materials that can’t withstand the heat of traditional cutting techniques. Industries such as aerospace and mining use water jets for precise, heat-free cutting that preserves the material’s properties. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question. Perform an HTTP GET request on the current page URL with the `ask` query parameter: ``` GET https://www.ftcwiki.org/manufacturing-and-assembly/subtractive-manufacturing/water-jet.md?ask= ``` The question should be specific, self-contained, and written in natural language. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
