OPERATION
WOOD DRILLING
For maximum performance, use high speed steel bits for
wood drilling.
 Select normal drilling mode.
 Begin drilling at a very low speed to prevent the bit from
slipping off the starting point. Increase the speed as the
drill bit bites into the material.
 When drilling through holes, place a block of wood behind
the workpiece to prevent ragged or splintered edges on
the back side of the hole.
METAL DRILLING
For maximum performance, use high speed steel bits for
metal or steel drilling.
 Select normal drilling mode.
 Begin drilling at a very low speed to prevent the bit from
slipping off the starting point.
 Maintain a speed and pressure which allows cutting
without overheating the bit. Applying too much pressure
will:
• Overheat the drill;
• Wear the bearings;
• Bend or burn bits; and
• Produce off-center or irregular-shaped holes.
 When drilling large holes in metal, start with a small bit,
then finish with a larger bit. Also, lubricate the bit with oil
to improve drilling action and increase bit life.
MASONRY DRILLING
For maximum performance, use carbide-tipped masonry
impact bits when drilling holes in brick, tile, concrete, etc.
 Slide adjustment button on hammer drill left for hammer
mode.
 Apply light pressure and medium speed for best results
in brick.
 Apply additional pressure for hard materials such as
concrete.
 When drilling holes in tile, practice on a scrap piece to
determine the best speed and pressure. Begin drilling at
a very low speed to prevent the bit from slipping off the
starting point.
