These augers feature Eijkelkamp's quality edelman auger bodies combined with the versatility of the AMS 5/8'' threaded, signature series, and quick connect connection systems.

Eijkelkamp edelman augers are widely used for the study of soil composition, soil profiling, and soil mapping. They feature a screw-like point at the base of the auger that enters into the soil as you push and turn the auger clockwise. The soil sample is guided into the auger by two vaulted vertical cutting blades. The vaulted design promotes soil digging and ensures a firm hold of the sample in the auger. Edelman augers utilize drilling bits made of untreated steel to avoid contamination of collected soil samples. There are four types of edelman augers: combination, clay, sand, and coarse sand. The combination soil edelman is the most commonly used, but the auger type should be chosen with respect to the soil conditions in order to achieve optimal results.

Open-Face Augers

The unique design of the open-face auger allows for quicker penetration into combination soils. Its advanced cutting head helps the auger pull itself into the ground with little effort and yields quicker soil penetration. The cylinder is made of thick, 10 gauge, high-carbon steel. The special cutting head and thick body make the open-face auger especially useful in tough combination soils – from mud and clay to hard-pan. The open design also allows for a quick visual profile of the sample and for easy soil extraction. A one-piece open-face auger is also available.

Dutch Augers

Dutch augers allow you to easily collect disturbed soil samples in heavily rooted areas. Hand forged from high-carbon steel and honed to a fine cutting edge, this auger will cut through highly fibrous and heavily rooted soils. It is excellent for use in forests, vineyards, and orchards. The unique open design of the dutch auger also allows for easier removal of hard or wet soils. The AMS dutch auger is similar in its design to the Eijkelkamp combination edelman auger.

AMS Connection Types

AMS signature series, threaded, and quick connect connections are used to connect AMS cross handles or slide hammers to AMS extensions,auger heads, and samplers. Each connection type has advantages that will make it more appropriate for particular uses or users. Please take into consideration that not all items will be available in every connection type. Contact us if you are unsure which connection type to use.

Helpful Tips for Using Signature Series and Threaded Connections

AMS recommends using non-adhesive fluoropolymer tape and wrench-tightening AMS threaded and signature series connections to help prevent the components from being damaged during heavy use and to minimize wear and tear over time. This also helps prevent threaded components from being difficult to disconnect after use with a slide hammer, hammer-head cross handle, or after hard twisting with a standard cross handle or ratcheting handle.

AMS Signature Series Connections

Signature series components feature a heavier thread than 5/8'' threaded connections. They are generally more robust and last longer under heavy use. Signature components can be connected and disconnected with only 2 1/2 turns, and have less risk of galling. Our most popular slide hammers, augers, core samplers, and soil sampling kits are available with signature series connections.

AMS 3/4'' & 5/8'' Threaded Connections

AMS 5/8'' and 3/4'' threaded connections use standard, national course, threads. 3/4'' are used with the new AMS professional line of augers and samplers. 5/8'' connections are the most
common and least expensive. Augers, core samplers, probes, slide hammers, hammer-head handles, and kits are available with threaded connections.

AMS Quick Connect Connection

The AMS quick connect button-and-hex coupling system allows components to connect and disconnect faster and with less hassle than threaded or signature series systems. When in use, the torque exerted on the system is placed on the hex – rather than threads – which makes the quick connect connection durable and prevents the components from binding together. Quick connect connections also allow for reverse augering with either a rubber-coated cross handle or ratcheting cross handle. Most augers and some soil sampling kits are available with AMS quick connect connections, but the connections are not compatible with AMS slide hammers or the hammer-head cross handle
