injury to your hands and arms. It could
also damage the Hammer Drill.
To prevent accidents, turn off the tool 12.

Metal Drilling Tips
Use high speed steel, carbide or 1.
specialty bits for metal drilling.
Secure work piece to keep it from 2.
moving during the drilling operation.
Use a punch (not included) to create a 3.
dimple for the bit to start.
Start by drilling slowly to keep bit from 4.
wandering away from your starting point.
As hole is established, increase speed. 5.

Secure work piece to keep it from 2.
moving during the drilling operation.
Start by drilling slowly to keep bit from 3.
wandering away from starting point.
Increase speed as hole is established.
To prevent or reduce “break out” when 4.
bit penetrates work piece, clamp a piece
of scrap material to back of work piece.
Do not lock Trigger in the ON position, as 5.
the bit can easily jam in wood and motor
must be stopped quickly.
Concrete Drilling Tips
Use carbide or specialty bits for concrete 1.
drilling.
Rock and masonry are generally drilled 2.
in the hammer (impact) drilling mode.
When drilling in walls, start with regular 3.
