Abstract: The present disclosure relates to a drill tool (1), such as a core drill tool (1), comprising a motor unit (2) and a gear unit (3). The motor unit (2) comprises an electric motor (4) and a motor drive shaft (5) that extends along a first longitudinal axis (6) from the electric motor (4) and protrudes out of a motor unit housing (7) via a motor exit aperture (8) in a housing end part (9) and comprises a drive shaft gear (10). The drive shaft gear (10) is adapted to propel a drill shaft (14) that extends along a second longitudinal axis (15) and comprises a tool holder (16) that is adapted to hold a tool. The housing end part (9) comprises a wall part (17) arranged transversally to the longitudinal axes (6, 15) and is adapted to close the gear unit cavity (11) and to separate the electric motor (4) from the gear unit cavity (11).

Abstract: A drill column end section assembly for a drill stand, comprising an end section (110) and a feed unit stopping element (120) arranged movable between a first position and a second position, wherein the stopping element (120), when in the first position, is arranged to prevent a drill stand feed unit from traversing past the drill column end section assembly, and, when in the second position, is arranged to allow the drill stand feed unit to traverse past the drill column end section assembly. The drill column end section assembly also comprises a positioning element (130) configured to releasably hold the stopping element (120) in the first position.
