Gardner Denver Model S63F Power Retract Feed Leg Drill w/FL7 Leg

Selling now for the low price of $1700.00!

   Gardner-Denver feed leg drills feature a quick-detachable coupling between feed leg and drill, which permits rapid disassembly for moving from heading to heading.  Special gland design in drills permits a change from dry to automatic wet drilling without taking the drill apart. 

    Mechanical Design features include: The backhead which is suitable for dry, wet, or air operated water control construction simply by changing the gland and tube. The feed control, pressure release valve and the air leg retraction valve are all conveniently located on the "D" handle giving the operator complete and safe control of the feed leg unit.

    The drill is equipped with a straight type throttle valve giving one-eighth, one-quarter, one-half and full open positions for easier collaring of holes in all types of ground and will not bind or leak. Air and Water Connection Elbows are designed for O-Ring use, making the swivel easy to operate without loss of air or water, and the water is screened to prevent plugging the water tube.

    The air in the feed leg is exhausted to atmosphere when the feed control valve is turned to off position, or when the pressure release valve is operated, which not only exhausts the air in the feed leg to atmosphere but also closes air passage to the leg.

 The desired tension on the swivel connection between the feed leg and the drill can be obtained by tightening or loosening the swivel adjusting nut. 

    You still get the same drilling muscle and operating flexibility and the same reliability of performance and low maintenance.
