Terex Bullet Tooth Digger Derrick Augers (BTA Series)
The Terex bullet tooth auger (BTA) is designed specifically to optimize the drilling performance of digger derricks in hard fracturable material such as limestone, lava, backfill material as well as cobbles and boulder type drilling conditions. They also drill great in soft dirt as well making it the best all around auger on the market today.
The Terex BTA augers have a unique cutting pattern that allows each tooth to cut a small track which improves cutting efficiency and tooth life.
Our cut pattern and tooth attack angle combine to allow the bullet teeth to act as “fingers” that penetrate thru and lift up fractured or broken material
