Cordless Drill and Corded Drill User Guide
How can I take care of my drill?
- Keep the drill in good repair.
- Insert bits fully and securely.
- Use the right drill and the right bit for the task.
- Keep drill bits sharp.
- When using a keyed chuck, tighten using all three holes to equalize shank pressure.
- Don’t lose you chuck key- tape it to a string and fasten it to the drill or cord.
Drill Cleaning Tips:
- Use a vacuum or compressor to clean fixtures and vents.
- Never submerge in water.
- Use a damp cloth or towel.
- Always use storage cases and keep the drill out of the weather and dust.
- Cordless drill batteries are best stored between 40 and 105 degrees F. High temperatures diminish battery capacity and low temperatures slow down battery reactions.
How to Sharpen Drill Bits:
It’s no secret that sharper drill bits drill faster and with less effort, and give a cleaner hole. Naturally sharpening drill bits your self is more cost effective than constantly purchasing new bits. But, you may be asking yourself, “How do I sharpen drill bits?” Well here are some ways to sharpen drill bits of various types.
- Twist Bits: Can be sharpened with a drill sharpener, grindstone jig or oilstone*. Shaping the drill tip’s angle correctly is essential for efficient cutting.
- Screwdriver: See Twist Bits above.
- Masonry: A drill sharpener or grindstone can sharpen tungsten carbide tips.
- Spur Point: Must be done by hand: sharpen the point and spurs with a fine file or edge of a fine grindstone; the correct angle between point and spurs is 90 degrees.
- Counter Sink: Can be sharpened with a fine triangular file.
- Tile Bit: The hard tungsten carbide and curved edge make sharpening difficult, but it can be carefully sharpened using an oilstone.
- Flat Wood Bit: Sharpen with a fine file, oilstone or grindstone.
- Forstner Bit: Sharpen on an oilstone or with a fine file.
- Wood Auger: A fine file or oilstone can be used to sharpen the spur and edges.
*Note: Titanium Nitride bits can’t be sharpened without ruining the coating.
Operating Your Drill Press:
Different operations require different drilling speeds. The most general rule is to use slow speed for large holes and fast speeds for small holes. Additionally metals usually require slow speeds while the appropriate speed for woods will vary by type. Its ok to experiment to see what speed works best. Table Selection for Bench top Drill Press.
If you buy a bench top drill press you will need to devote workbench space to the machine. One advantage of the floor model if workbench space is limited is that they are free standing.
- Round Tables feature oil grooves which clamps can be attached to. Good for wood and metal.
- Rectangular tables lack oil grooves, and are best suited for woodworking. Features pierced slots for clamps.
Drill Press Safety:
The same precautions that I outlined in the section on Cordless Drill apply here, but with several additional precautions:
- Clamp and secure all work before using the drill press.
- Watch for loose clothing and hair that may be caught in the revolving parts of the drill press.
- Always wear safety goggles while working with the press.
- Turn off power before making adjustments.
- Use only sharp drill bits.
- Never secure a workpiece with your hand.
- Keep workspace around the press clean.
Drill Safety 101:
1. Own and wear safety glasses.
2. Do not wear loose fitting clothing.
3. Wear clothing that will cover and protect your body, but not get caught up in the moving parts of the drill.
4. Use a dust mask if needed.
5. Hearing protection never hurt anyone.
6. Loose fitting gloves might get caught by moving devices.
1. Maintain your drill and bits
2. Clamp and secure whatever your working on as a general rule.
3. Mark the center of the hole or use a center punch to mark it. Then place the drill in the center of the hole.
4. Predrill holes for woodscrews.
5. Start slowly and slowly increase speed.
6. Vary the pressure and don’t let the drill bind.
7. Don’t force the drill, let the machine do the work.
8. Slower speeds for thicker wood and high speed for metals.
9. Withdraw the bit often while drilling to remove chips.
10. Brush these away, blow on them and they could end up in your eyes.
11. Use a side handle and hold the drill firmly with both hands.
12. Take your time
Tip: Avoid splintering: Wood tends to splinter as the bit breaks through the opposite side of the work piece. This can be avoided by clamping cardboard to the back of the work piece.
