摘  要:
This paper examines the portable earth auger bit, its manufacture, operating environment and efficiency. The bit is used in steep rocky mountain areas which contain 40%~60% stone. The bits studied showed to have high productivity, a quicker digging speed, low cost, low labour intensity, and met forestry requirements in all other parameters.
