Operation DRILLING 1. Always unplug the drill when attaching or changing bits or accessories. 2. Use sharp drill bits only. For WOOD, use twist drill bits, spade bits, power auger bits, or hole saws. For METAL, use high speed steel twist drill bits or hole saws. For MASONRY, such as brick, cement, cinder block, etc., use carbide-tipped bits. 3. Be sure the material to be drilled is anchored or clamped firmly. If drilling thin material, use a wood “back-up” block to prevent damage to the material. 4. Always apply pressure in a straight line with the bit. Use enough pressure to keep the drill biting, but do not push hard enough to stall the motor or deflect the bit. 5. Hold the tool firmly to control the twisting action of the drill. 6. IF THE DRILL STALLS, it is usually because it is being overloaded or improperly used. RELEASE THE TRIGGER IMMEDIATELY, remove the drill bit from work, and determine cause of stalling. DO NOT CLICK TRIGGER OFF AND ON IN TO START A STALLED DRILL — THIS CAN DAMAGE THE 7. To minimize stalling or breaking through the material, on drill and ease the bit through the last fractional hole. 8. Keep the motor running when pulling the bit out of a This will help prevent jamming. 9. With Variable Speed Drills there is no need to center punch the point to be drilled. Use a slow speed to start the hole and accelerate by squeezing the trigger harder when the hole is deep enough to drill without the bit skipping out. Keyed Chucks Open chuck jaws by turning collar with fingers and insert shank of bit about 3/4" into chuck. Tighten chuck collar by hand. Place chuck key in each of the three holes, and tighten in CLOCKWISE direction. It’s important to tighten chuck with all three holes to prevent slippage. To release bit, turn chuck key COUNTERCLOCKWISE in just one hole, then loosen the chuck by hand. Any authorized DEWALT service center can install a keyless chuck in place of a keyed chuck. Keyless Chucks Open chuck jaws by turning plastic collar with fingers and insert shank of bit about 3/4" into chuck. Tighten plastic collar CLOCKWISE while depressing spindle lock button on the right side of the tool housing (Fig. 4). To release bit, turn plastic collar COUNTERCLOCKWISE while depressing the spindle lock button (Fig. 4). NOTE: DO NOT DEPRESS LOCK BUTTON WHILE OPERATING DRILL or while the chuck is moving. 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 sulfurized cutting oil or lard oil; bacon-grease will also serve the purpose. 4 Drilling in Wood Holes in wood can be made with the same These bits may overheat unless pulled out frequently from the flutes. For larger holes, use power drill that is apt to splinter should be backed up with a block Drilling in Masonry Use carbide tipped masonry bits at low speeds.
