"Featuring standard heavy-duty 1in flighting and optional extra heavy duty 1-1/2in flight, this tool is commonly used for drilling construction footings," said Dale Putman, product support manager.

"The flighting pitch enhances material flow from the tooth cutting area, which increases productivity. In addition, tooth angles and location are precisely controlled to improve penetration." The Foundation High Production Auger has a square drive pilot bit for up to 12in diameter.

Terex will be showing the Foundation High Production Auger at the forthcoming MINExpo event in Las Vegas and during that event, it will also show other auger tools for medium to hard ground and for loose and soft materials.

The Terex Bullet Tooth Rock Auger is described as being ideal for hard limestone, cobbles, boulders, and fractural rock formations. Standard flighting is 1in and extra heavy-duty flighting of 1-1/2in is available.

"The cut pattern and tooth attack angle allow the bullet teeth to act as ‘fingers' that penetrate through and lift up fractured or broken material," said Putman.

The tool works with the digger derrick core barrel with an extendable pilot bit option to improve functionality and increase productivity.

Terex Dirt Auger also has standard 1in flighting and optional 1-1/2in flighting. This tool improves drill footage in loose to compacted soils, stiff clay, loose gravel, and soft shale.
