发明名称 Hole making system
摘要 A hole making system for efficiently cutting a hole into a ground surface and for allowing effective removal of the plug. The inventive device includes a cutter assembly, a tamper assembly slidably positioned within the cutter assembly, and a hammer assembly slidably positioned about the tamper assembly for driving the cutter assembly into a ground surface. The tamper assembly includes a first depth indicator and a second depth indicator for indicating to the user the approximate depth of the hole being created. An alignment level is preferably positioned within a handle assembly of the tamper assembly for indicating to the operator the relative vertical alignment of the cutter assembly.
