Watermelon mill
The watermelon mill is specifically designed for casing exit and ensuring the full-gauge casing window while eliminating burrs, irregularities, and potential sticking points. It is also used for uniform reaming of the production interval. The WM is supplied with a starter mill as part of the window milling and sidetracking system (see the catalog vol.2 - Casing exit/ Sidetracking Systems).
