The Stand Alone Core Barrel 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. The optional pilot bit is important for achieving a straight starter track.
In addition, it is designed for easy plug removal, increasing drilling productivity. A unique tooth pattern allows the rock plug to easily fall out of the barrel when the operator ratchets the rotation of the tool.
Available in various diameters ranging from 18” to 30” and features a barrel wall of 5/8”, the heavy duty hex hub is either 2-1/2” or 2-5/8” and it comes with a Dom ST5 2-3/4” shaft. The overall length of the tool is 104 inches. Access to the C-10 bullet teeth provides for easy removal and replacement.
