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
 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
 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 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.
