DRIVING SCREWS
Proper settings for driving screws:
1. Set the ring on the lowest setting to begin.
2. Try setting the first screw in a piece of scrap material. If the drill drives smoothly, proceed with this setting.
3. If the drill's clutch slips, increase the torque setting and try again until the drill drives the screw
without incident.
For the best results:
1. Always start slowly and gradually increase the speed of the drill.
2. Always keep the driver bit straight to prevent damage to the screw.
3. Hold the drill with both hands to ensure control if the bit should stick or slip.
4. If the screws are difficult to tighten, try applying a small amount of washing liquid or soap as lubricant.
DRILLING METAL
1. For metal, use high speed steel twist drill bits or hole saws.
2. Apply a lubricant, such as cutting oil, to the tip of the bit when drilling metals other than cast iron, aluminum,
copper and brass.
3. Use HSS drill bits when drilling metal.
4. Start with a small hole and then enlarge to the required size. Make sure the bit is actually cutting and not
spinning in the hole, as this will dull the edges of the bit.
5. Keep enough pressure on the bit to keep it drilling through the material.
DRILLING MASONRY
1. For masonry, such as brick, cement, cinder block, etc., use carbide-tipped bits.
2. Masonry can be brittle so be careful not to apply too much pressure and crack the material.
3. Apply enough pressure to keep the bit cutting and not spinning in the hole, as this will dull the edges
of the bit.
4. Bricks and similar soft materials will require less pressure, concrete will require much more.
5. Use masonry bits when drilling in soft masonry.
DRILLING WOOD
1. For wood, use twist drill bits, spade bits, power auger bits, or hole saws. Pull the bits out of the hole
frequently to clear chips from the flutes as an overburdened bit may overheat.
2. Use a block of wood to back up work pieces that may splinter.
3. Use spade bits when drilling large diameter holes in wood.
4. to prevent wood from splitting, drill pilot holes in the wood before driving in the screws.
