When drilling in rocky soils, heavy-duty augers are recommended. In addition to different flighting, these augers are equipped with a heavy-duty tooth and side cutting blades.
All heavy-duty augers come complete with a standard bolt-on point and dirt tooth blades. Points can be replaced with a standard point for ordinary drilling or a carbide tip point for abrasive soils. All blades are held in place with rubber locks.
