OPERATION
WOOD AND METAL DRILLING
For maximum performance, use high speed steel bits for
wood or metal drilling. Select drilling mode by rotating the
torque adjustment ring to the drill bit icon. Begin drilling
at a very low speed to prevent the bit from slipping off the
starting point.
Wood Drilling
Select drill mode.

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 and Steel Drilling
Select drill mode.

Use a light oil on the drill bit to keep it from overheating.

The oil will prolong the life of the bit and increase the
drilling action.
Maintain a speed and pressure which allows cutting

without overheating the bit. Applying too much pressure
will:
• Overheat the hammer 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.

MASONRY DRILLING
For maximum performance, use carbide-tipped masonry
impact bits or designated hammer drill bits when drilling
holes in brick, tile, concrete, etc.
Select hammer mode.

Apply light pressure at 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.
