HAMMER DRILLING
When drilling in concrete, granite, tile, marble, etc. use the hammer action by
pressing the button on the marked side.
1. Be sure to use a tungsten carbide-tipped bit. When the hole becomes
clogged with chips, do not apply more pressure. Allow the tool to idle and
partially remove the bit from the hole.
2. Repeat this action until the hole is cleaned out.
METAL DRILLING
1. Use a center punch to mark the hole location on the workpiece.
2. Begin by drilling at a low speed to prevent the bit from slipping.
3. Use a light oil on the bit to keep it from overheating.
4. Maintain a consistent speed and pressure on the drill until the hole is
completed.
_, WARNING: Be prepared for binding or breakthrough. When these situations
occur, the hammer drill has a tendency to grab and kick in the opposite direction
and could cause loss of control when breaking through material. This loss of
control can result in possible serious injury. Do not lock the trigger on jobs where
your hammer drill may need to be stopped suddenly.
