Pusher Legs and Stoper Drills
Air-operated feed legs that supply thrust to a handheld drill, and integrated stopers for drilling upwards into a back. Feed force is what turns a handheld drill into a production tool.
Features
- A pusher leg supplies steady feed force, which stops the bit bouncing and raises penetration rate substantially.
- Leg stroke and extended length have to suit the hole length and the available standing room.
- Stoper drills combine drill and feed leg in one tool for up-holes, with an exhaust arrangement that directs water and air away from the operator.
- Feed pressure is adjustable and is set from observed penetration rather than run at maximum.
- Leg seals and the feed control valve are the routine service items and should be stocked as a kit.
