The Hollow Stem Auger te recognized as a versatile, fast, effective tool for advancing the drill hole and "keeping the hole open." Once the drilling depth is achieved, the center stem of the auger is quickly removed and allows working inside the Hollow Stem using coring tools, soil sampling equipment, down-the-hote hammers or for inserting tie back rods and cables, well points and drain pipes. The Hollow Stem is widely used in conjunction with Ground Water Monitoring drilling applications and hazardous waste operations.

Cutter heads for Hollow Stem Augers are designed with replaceable-type carbide inserts. The cutter head design allows the center plug with the pilot bit to be positioned slightly ahead of the cutter head. A hollow bore drill head allows the center plug to be withdrawn to the surface when the desired depth of the hole is reached. Center stem rods are used to connect the center plug to the center stem adapter and adapter cap of the auger string at the surface.

For a complete lead assembly, the following items ate required:

With the addition of a Cutter Head, conveyor flight augers are commonly used for drilling to 100 ft. (30.5mm) depths where soil cover permits. Obviously, the sizes are many, but the most commonly used sizes are listed as standard. Cutter heads generally are somewhat larger in diameter than the conveyor flight to provide clearance for the cuttings to work easily to the surface. Optional features such as "hard facing" of the augers can be provided for added tool life when drilling abrasive formations. Flight connector pins are the drive pin type—simple but rugged. Conveyor flight auger lengths vary but 3 ft. and 5 ft. (.9144m - 1.524m) are the most popular lengths. Consult the chart for pitch and standard connections commonly used for auger boring applications. All flight augers are timed or synchronized—there are no gaps in the flight between auger sections.

This drill head or "Cutter Head" is designed for use on Conveyor Flight type augers. The head is constructed of high quality steet and designed for use with hard faced or carbide inset type finger cutters. Carbide insert fingers are commonly used to drill reasonably hard rock and shales. The cutter head is held on the flight auger by means of a drive clip pin and rotated by the standard shank and socket connection. Finger teeth are held in place by a drive wedge or soft wire pins. Select cutter head diameter on basis of hole diameter desired and select flight size or diameter, about 10% less than cutter head diameter...or hole size.

Steel drive pins are used to secure connecting ends of conveyor flight augers. The drive pin is driven into place with a hammer and removed by the pointed end of the hammer. Since driving will gradually weaken the clip, replacements should always be considered when ordering. Sizes will depend upon augers in use.

Repair connectors are used for replacing worn shank or socket connections on conveyor or auger flights.

Sub adapters are helpful when switching from auger tools to sampling tools having drill rod threads. Standard adapters are usually pin to pin connections.

This hammer is ideal for driving clip pins on conveyor flight augers.

For use with drill rigs not having hollow spindles. Adapts direct to rotary stem or kelly. Water is fed into side part and down through drill rods. Used with auger drills for either high or low speed application, coring fish tailing, or small roller rock bits. Advise spindle connection, inlet port and rod size desired. Working pressure 150 PSI MAX. Ball Bearing type with 3/4" and 1-1/4" inlet ports.
