Terex stand alone core barrel eliminates need for auger drill attachment

October 18, 2016 – Terex Utilities has a new auger tool for digger derricks: the “stand alone core barrel”. It fits directly onto a standard Kelly bar and can be stowed like a standard auger on the boom, eliminating the need for any attachments or having to remove for transportation.

For applications requiring drilling to begin at ground level, a removable pilot bit can be used to stabilize the stand alone core barrel in order to start a hole. Once initial penetration is achieved, the pilot bit can be removed.

A unique tooth pattern allows the rock plug to fall out of the barrel when the operator ratchets the rotation of the tool, Terex explains, while other core barrels require workers to hammer the core out of the barrel.

The product is available in various diameters ranging from 18 in. to 30 in. and features a barrel wall of 5/8 in. The heavy-duty hex hub is either 2-1/2 in. or 2-5/8 in. and it comes with a Dom ST5 2-3/4-in. shaft. The overall length of the tool is 104 in.
