It is used for grinding the convex backs of cabochons, shaping rounded stone profiles, and any application where a flat wheel would only contact the highest point of a curved surface rather than grinding evenly across the full curve.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eQ: Should diamond concave wheels be used wet or dry?\u003c\/strong\u003e\u003cbr\u003eA: Always use wet. Run water over the wheel continuously during grinding to cool the diamond surface, prevent heat damage, and suppress stone dust.\u003c\/li\u003e\n\u003c\/ul\u003e","products":[],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0575\/4542\/4942\/collections\/Diamond_Concave_Wheel.png?v=1738200449","url":"https:\/\/hanslapidarytool.com\/collections\/diamond-concave-wheels.oembed","provider":" Hans Lapidary Tool","version":"1.0","type":"link"}
