Downhole Tool Head For Releasing Precipitated Solids

The present invention relates to a downhole tool head (1) for mounting onto a downhole tool (10) for drilling in a formation downhole or for releasing precipitated solids (2) such as ice scales or the like in a cavity fluid in a pipeline a casing (3) a well or any other cavity downhole. The downhole tool head comprises a hollow cylindrical body (4) with a circumferential wall (5) extending from a base part of the body the circumferential wall having a circumferential rim (6) in its end opposite the base part. The circumferential rim (6) comprises a plurality of edges (8) for cutting grinding drilling and/or milling and the base part has a plurality of through-going holes (9) for letting cavity fluid comprising precipitated solids pass the holes.
