Abstract

Freseverktøy for bruk i energiutvinnende brønner Innbefattende et rørformet element (1) med en langsgå-ende boring (2) for føring av fluid, og radlelt forløpende skjærblader (5). Oppad rettede porter (70) forløper fra boringen (2) til et sted under skjæreggen (6) av bladene (5) for positiv fjerning av sponavskjær.Milling tools for use in energy-producing wells Including a tubular element (1) with a longitudinal bore (2) for guiding fluid, and radially extending cutting blades (5). Upwardly directed gates (70) extend from the bore (2) to a place below the cutting edge (6) of the blades (5) for positive removal of chip cuttings.
