OPERATION
WOOD AND METAL DRILLING
For maximum performance, use high speed steel bits for
wood or metal drilling. Select drilling mode. 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.
