The present invention relates to a biopsy device (1) for obtaining a tissue sample. The biopsy device comprises an elongated tube shaped drill (2), extending along a longitudinal axis A, and comprising a cutting edge arrangement (3) at a distal end (4) of said drill (2). The drill (2) further comprises at least one flute (5) extending helically, along said longitudinal axis A, at an outer surface (6) of said drill (2), wherein said flute (5) extends from said distal end (4) and along a substantial part (7) of said outer surface (6) of said drill (2). The drill (2) is provided with an opening (10) at its distal end (4), wherein said opening (10) being in communication with a cavity (16) adapted to receive said tissue sample. The cutting edge arrangement (3) comprises a first cutting edge (11), adapted to perform a cutting action when said drill (2) is rotated in a first direction (d), and said first cutting edge (11) comprises at least one longitudinal cutting edge (13) extending essentially along said longitudinal axis A.
