FIELD: physics.
SUBSTANCE: tool comprises connection section (12) for fastening in drilling machine and tool head (14), on which cutting means (18) are arranged along circumference. Tool head (14) has at least one lateral through slot (20), which in axial direction extends from end (22) of tool head (14) along tool longitudinal axis (A), and exhaust channel (11) for suction of drilling dust, at least partially extending axially along longitudinal axis (A) of tool, wherein exhaust channel (11) passes inside tool shank (16) from end (22) of tool head (14) and enters into connecting hole (13) on shank (16) circle.
EFFECT: higher convenience of operation due to reduced load on operator.
