USExploration Equipment Co. has designed a hollow-stem auger cutterhead assembly that performs in clay, hardpan, glacial till, sand, gravel, cobbles, weathered rock, shale and soft limestone. Flight segments provide the correct angle of approach, ensuring the blades and bullets cut with efficiency. These blades and bullets throw material out, away from the center of the borehole, so little or no soil plug is developed in non-flowing material. The cutting face is less crowded to prevent material from balling-up and impeding penetration. This standard design can be adapted to any hollow-stem auger pin. USExploration Equipment Co.
