A new video from Terex Utilities demonstrates the importance of selecting the right auger tool for the job conditions.
Selection factors include auger or barrel tools, various types of teeth, and tool size. “With the right tool, you can reduce dig time, eliminate overheating, and improve productivity,” said Greg Adler, regional account manager for auger tooling.
The video shows Terex Utilities performing a side-by-side comparison of its TXC Auger and BTA Spiral auger with carbide bullet teeth drilling into concrete.
The TXC auger is best for loose soil, compacted soil, stiff clay, shale, cobbles, and medium rock. In contrast, the BTA Spiral is efficient for drilling into hard rock and concrete. After about 12 min., there is a drastic contrast in the amount of work accomplished by the BTA Spiral.
“Be sure to match the tool with the ground conditions. Most tool specifications will include a description of the type of applications for which the auger tool or barrel is designed. In addition, the type of teeth on the pilot bit is related directly to the application it’s designed to work in,” said Adler. He also recommends that the pilot bit and flighting teeth are compatible, with the same strength and cutting characteristics.
“Augers have flights to lift the spoils that are loosened by the teeth and a pilot bit that stabilizes the drilling process for a straight hole,” said Dale Putman, product support manager. “Core barrels cut a single track and apply more pressure per tooth. They remove rock by lifting it out as individual plugs.” The second demonstration in the video is of the Terex Stand Alone Core Barrel, shows just that process in action.
