[TowerTalk] Tools for Installing Ground Rod?

[Larry Burke]

<snip>

Harbor Freight carries a 1" rotary hammer that one member of TowerTalk
recommended some time back.  They often have it on sale for $60-$70.  It is
also avaiilable in their stores.  Can't testify to quality, but it sppears
identical in build to the Bosch, etc.

Never have seen the bit though that fits a ground rod.

According to the Harbor Freight web site these are currently on sale for
$59.99.  Sale ends Jan 30. Would like to hear from anyone who has used this
particular model to drive a ground rod. Also curious if there is a
difference between an "SDS" bit and an "SDS Max" bit. A quick search of the
web indicates an SDS Max ground rod bit will cost as much as the rotor
hammer itself. There is an interesting alternative way to use a cheaper bit
at: http://www.n4lcd.com/groundrod/ . Although some might argue this might
not be as safe as the bit intended for the purpose.
