摘要： A drill bit and a single pass drilling apparatus are disclosed. The one-piece drill bit is rotatable about a drilling axis and has a connection portion, adapted to be rigidly connected to a drill steel, a pilot part and a reamer part. The reamer part has a leading and at least one trailing first rock machining means disposed on one side of the pilot part within a sector defined by sector angle θ. At least one of the trailing first rock machining means is axially spaced from the leading first rock machining means in the direction toward the trailing end of the drill bit.

摘要： The present invention relates to a drill bit and a single pass drilling apparatus. The one-piece drill bit has a connection portion, adapted to be rigidly connected to a drill steel, a pilot part and a reamer part. The pilot part has first rock machining means. The reamer part has a first center line and second rock machining means. The second rock machining means is provided axially between said connection portion and said first rock machining means and to one side of the pilot part. The drill bit has a rotational direction. A side of the pilot part facing away from the reamer part is provided with a wear resistant means. The wear resistant means is integral with the first rock machining means.

摘要： The present invention relates to a single pass drilling apparatus, a rock bolt, use of a drill bit and a method for single pass rock bolting for reinforcement and stabilization of excavations. The single pass drilling apparatus comprises an elongated drill steel (11) having a leading (12) and a trailing end (1 3) with reference to a drilling direction (F). The leading end (12) has a connection portion. A one-piece drill bit (16) is utilized having rock machining means (17,18;17′18′). The drill bit is connectable to the drill steel. The single pass drilling apparatus (10) further comprises a rock bolt (21;121,221;321) adapted to at least partially enclose the drill steel (11). The greatest diametrical dimension (DB) of the drill bit (16) is smaller than the smallest diametrical dimension (DI) of the rock bolt.
