Geotechnical Equipment
Geotechnical Equipment and Sampling Products
With unsurpassed commitment to quality, drilling companies enjoy the assurance of high quality tools that are specifically designed for the demanding challenges of geotechnical diamond drilling. The performance offered by these tools allows diamond drilling teams to ensure better quality constructions, while increasing productivity.
Split tube sampler
When your drilling needs call for a split tube sampler, our full line of quality, DCDMA-approved samplers are ready for use in any drilling situation.
Thin wall tube sampler
Whether you need a 2-5" thin wall, 3" SST, or 3" seamless Shelby tube, our thin wall tube samplers and head assemblies meet or exceed all steel requirements listed in DCDMA specifications.
Heavy Duty split tube sampler
Well-built, quality-crafted, heavy-duty split tube samplers are 2" O.D. splitspoons that are heat treated for longer wear.
The complete sampler includes a durable head, a split- section that is made of high quality 4130 steel, and a heat treated shoe. Samplers are available in 2", 2-1/2", or 3" diameter, with either a standard fine thread shoe (8 threads per inch) or a quick thread shoe (4 threads per inch). We also offer spilt tube sampler accessories, including steel and synthetic basket retainers, flap valves, and liners.
Augers
Heavy Duty Hollow Stem Augers
Hollow stem augers are full fluted 5ft. lengths that are built for toughness, but light enough for easy handling. We offer four sizes of hollow stem, splined, sleeve type augers:
- 2 ¼ I.D. (5 5/8 O.D.)
- 3 ¼ I.D. (6 5/8 O.D.)
- 4 ¼ I.D. (7 5/8 O.D.)
- 6 ¼ I.D. (9 5/8 O.D.)
Any auger can be quickly adapted to other makes or sizes using an adapter which is also available.
Auger Connection
EPL offers a superior design slip fit auger connection with a course spline and a 2-bolt coupling. The 2-bolt coupling creates a more durable connection for deep drilling situations. The coupling also allows the operator to easily remove one bolt and install a thread protector to be prepared for shallow drilling. The coupling is made using a heat-treated alloy steel investment casting, which adds to the strength of the product.
Solid Flight Augers
Our continuous flight augers maintain high standards of quality. These augers are made from 4130 cold drawn, stress relief annealed steel tubing to assure high quality and maximum strength. The carbon steel shaft minimizes weight, and ensures maximum strength and rigidity. The flights are abrasion-resistant, and formed with a slightly tapered concave surface that pushes soil toward the shaft in order to minimize clogging and auger drag.
Dry Augers
EPL dry auger system features simple, inexpensive compression seals, auger bolt caps, and O-rings, which provide leak proof stringing for the driller, and ensure the flexibility of conventional augers. This eliminates the worry of leaving water-resistant augers in the ground because they break when they hit a cobble.
It also eliminates the problem of water flowing in through the auger connections when drilling below the water table, and fluids flowing out of the connections during mud rotary drilling. These augers save time, reduce materials, and eliminate cross-contamination headaches.
The dry auger system is adaptable to all sizes – Diedrich, CME, Foremost, and other types of auger connections.
Tricone
Tricones for all of your overburden, destructive or reverse circulation drilling needs. Our blast hole bits come with a variety of different connections, which allow them to fit most drills. Our steel tooth and carbide bits are suitable for all types of rock formations, from very soft to very hard.
