20″ Digger Derrick Bullet Tooth Auger

Terex 20 inch bullet tooth digger derrick auger with 60-inch flighting.  Designed specifically to optimize the drilling performance of digger derricks in hard fracturable materials.

If you are drilling in fractured rock (limestone, lava rock, medium sandstone, coral, and frozen earth) or drilling in a mix of dirt and rock, this is the tool that you need. The single row bullet tooth rock auger is our #1 selling auger. It will destroy fractured rock, frozen soil, compacted soil, and contaminated fill dirt.

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

These bullet tooth augers perform much better and reduces total tooth cost over standard carbide flat teeth. This saves you time, money, and dramatically reduces equipment wear.
