Drilling
in Wood
Holes in wood can be made with the same twist drills used for metal. These bits may overheat
unless pulled out frequently to clear chips from the flutes. For larger holes, use spade bits, power
auger bits, or hole saws. Work that is likely to splinter should be backed up with a block of wood.
Drilling
in Metal
Use a cutting lubricant when drilling metals. The exceptions are cast iron and brass which
should be drilled dry. The cutting lubricants that work best are sulphurized cutting oil or lard oil;
bacon grease will also serve the purpose.
Drilling
in Masonry
Use carbide tipped masonry bits at low speeds. Keep even force on the drill but not so much
that you crack the brittle materials. A smooth, even flow of dust indicates the proper drilling rate.
MAINTENANCE
_CAUTION:
With the motor running, blow dirt and dust out of all air vents with dry air at least
once a week. Wear safety glasses when performing this. Exterior plastic parts may be cleaned
with a damp cloth and mild detergent. Although these parts are highly solvent resistant, NEVER
use solvents.
If replacement of the power cord is necessary, the tool should be taken to a DEWALT factory
service center, a DEWALT authorized service center or other qualified service personnel in order
to avoid a safety hazard. To locate an authorized service center, please contact DEWALT
