Hollow Stem Auger (Flightless) Extensions – Manufactured by USExploration Equipment Company and designed to be used above grade, allowing the auger string to stop rotation at various depths, depending on rig stroke length, “jack-up” height, sampling frequency or well installation requirements.

The Flightless Extension typically is the same inside diameter (ID) as the tool string being advanced, however it can be fitted with a wide range of hollow stem auger Pin (male) and Box (female) connections, depending on rig spindle attachments.

This unique tool allows for a individualized “tool string” operating length, while maintaining clear access to the (cased) bore hole.

Specify rig spindle attachment, desired assembly length and tool string being advanced when ordering – special combinations available upon request.

3-1/4-inch (83mm) inside diameter Octagonal style Hollow Stem Auger Pin (right) & Box (left)

Octagonal Hollow Stem Augers & Accessories – are available from USExploration Equipment and represent a rugged alternative to consider when drilling in difficult overburden.

The relatively simple design, thick wall Axle (mid-body) and steep pitch on the flight, make these hollow stem augers an effective digging tool when the going gets a little rough.

Short auger sections with NPT threaded fittings give you the best tool for circulating cuttings from the Bit back to the surface.

Wash-Tees for Rotary & Diamond Drilling inside Hollow Stem Augers – are manufactured by USExploration Equipment Company and are designed to serve as a collar for the bore hole at the surface - while “rotary drilling” is underway and you are using hollow stem augers as surface casing.

The wash tee gives you the tool needed to circulate your returns from the open hole through your mud system.

When ordering, simply match your inside diameter to your appropriate pin connection and get the correct assembly headed to your job site.

Hollow Stem Auger (Spears/ Taps) Retrievers – are manufactured by USExploration Equipment Company and are normally used when a formation has caved in around the tool string, or a coupling has failed leaving good augers down-hole.

The appropriate fishing tool should first be selected by coupling inside dimension, number of keys and finally auger type – standard or heavy duty.

The inside or “Tap” type is ideal for recovering hollow stem augers, because the mid-bodies are much larger then solid stem augers, making a corkscrew type almost impossible to apply successfully – so it is much easier to get the hardened threads of the “Tap” inside the coupling and make a straight pull.

Auger Holders are available with single handle or double style (above)

Auger Holders (Forks or Pans) for Hollow Stem Augers – from USExploration Equipment Company are used to keep auger assemblies from heading back down the bore hole, once the auger extraction process begins.

This simple tool slides in between the “Pitch” of the flight, and tightly up against the outside of the Axle (mid-body) of the auger itself.

Since the Holder diameter is larger then the bore hole created by your augers, the fork serves as your only chance to keep tools from heading back down the hole, once you have tripped (TD) off bottom.

Our Auger Hoisting Assembly is the safest way to extract your augers from the hole.

Hoisting Tools & Accessories for Hollow Stem Augers – are manufactured by USExploration Equipment Company with 2-Key or 3-Key couplings.

The assembly is designed to fit over the exposed hollow stem auger pin at the surface and along with chains attached to a corresponding hollow stem auger box, provides a method for a straight, single line pull with your rig’s main hoist.

The Auger Hoisting Assembly is designed to use standard Lockbolts in the box assembly to pull the tool string vertically either when it is trapped by the formation or during the “back-filling” portion of a monitoring well installation.

3-1/4-inch (83mm) inside diameter Cutter Blade x Bullet Bit Cutterhead. The most efficient down-hole cutting tool in the industry – period!

The industry’s Premier Cutterhead for Hollow Stem Augers – is manufactured by USExploration Equipment Company to meet rigid compatibility specifications.

We start with our standard 2-Key or 3-Key cutterhead body designed to handle specially engineered Flight Segments, Cutter Blades, multiple sizes of Bullet Bits and Spade Bits assuring the ultimate cutting tool for your formation.

This fully-engineered cutterhead maximizes cutting performance, because it represents the hard lessons learned as a result of the accumulated trial and error from other designs over the many years of hollow stem auger exploration.

No other cutterhead digs in more diverse formations then this one…period!

Simply match your hollow stem auger coupling type and experience what true cutterhead engineering can do for your daily footage rates
