The patented centerline cutting design of the 4th Generation drill head delivers the following benefits:
- Reduces the torque required to obtain efficient cutting,
- Efficient cutting improves the performance of all machines large or small,
- Center line cut design travels straight and improves on grade bores,
- Unlike a duck bill design the 4th Generation assembly doesn't loose its steer when drilling out of a steer,
- Allows the operator to engage and cut an entrance hole in a manhole or basement wall.
In summary, the 4th Generation drill head will travel straighter and drill faster while placing less stress on the drill and drill pipe.
