When drilling in wood, composition materials and
plastic, select the drill operating mode. Start the drill
slowly, gradually increasing speed as you drill. Se-
lect low speeds for plastics with a low melting point.

When drilling in metal, select the drill operating
mode. Use high speed steel twist drills or hole
saws. Use a center punch to start the hole. Lubri-
cate drill bits with cutting oil when drilling in iron
or steel. Use a coolant when drilling in nonferrous
metals such as copper, brass or aluminum. Back
the material to prevent binding and distortion on
breakthrough.

When drilling in masonry, select the rotary hammer
operating mode. Use high speed carbide-tipped
bits. Drilling soft masonry materials such as cinder

not let the bit spin in the hole without cutting. Do
not use water to settle dust or to cool bit. Do not
attempt to drill through steel reinforcing rods. Both

If the speed begins to drop off when drilling large
