A pneumatic drilling tool (10) comprising a spindle (21), a pneumatic motor for driving said spindle (21), an air inlet portion (14) for supplying pressurised air to drive the motor, a housing (12,13, 25) that at least partly houses the motor and the spindle (21), wherein the spindle (21) is configured to hold a drilling implement (11), which is arranged to extend out from a front housing (12) of said housing during operation. A disposal collector (18) is arranged for collecting drill chips (22) during operation, wherein an air nozzle (23) is arranged in a flow passage (30) adjacent the front housing (12), the nozzle having an outlet (26) that is directed away from the front housing (12) into the disposal collector (18) to thereby create a suction effect from the front housing (12) into the disposal collector (18), which disposal collector (18) has a permeable portion (28) that allows air to pass through it but keeps the drill chips inside, wherein an air conduction conduit (15) is arranged from the air inlet portion (14) to the air nozzle (23) to provide the suction effect. |
