TOOL TIPS
Following a few simple tips will reduce wear
on the tool and the chance of injury to the
operator.
The high efficiency available from the BOSCH
Rotary Hammer can only be obtained if sharp
and undamaged drilling tools are used. Note
that the costs for maintaining sharp drilling
tools are more than offset by the time lost in
operating dull drilling tools.
