Why Choose a Corded Drill?
Before we dive into how to use it, let’s quickly touch on why a corded drill is a fantastic choice, especially for beginners. Unlike their cordless cousins, corded drills offer:
- Consistent Power: You never have to worry about a dying battery. They deliver uninterrupted, high-torque power, which is great for tougher materials like hardwoods or concrete.
- Lighter Weight: Often, corded drills are lighter than their battery-powered counterparts, making them easier to handle for extended periods.
- Cost-Effective: Generally, corded drills are more budget-friendly upfront.
While cordless drills offer portability, for sheer power and reliability, especially when you’re just starting out, a corded drill is an excellent workhorse.
Essential Parts of a Corded Drill
Understanding the different parts of your drill will make operating it much easier. Here are the key components:
- Chuck: This is the part that holds the drill bit or screwdriver bit. Most modern drills have a keyless chuck, meaning you can tighten or loosen it by hand.
- Chuck Sleeve: The rotating part of the chuck that you grip to tighten or loosen it.
- Variable Speed Trigger: This allows you to control the speed of the drill. The harder you squeeze, the faster it spins.
- Forward/Reverse Switch: Usually located near the trigger, this lets you change the direction the drill spins. Forward is for drilling and tightening screws, while reverse is for removing screws or backing out a stuck bit.
- Mode Selector (if applicable): Some drills have a switch to select between drilling, hammer drilling (for masonry), and screwdriving modes.
- Power Cord: The lifeline that connects your drill to electricity.
- Handle/Grip: Where you hold the drill for control and comfort.
- Depth Stop (optional): A rod that attaches to the drill to set a maximum drilling depth.
Tools and Materials You’ll Need
To get started, gather these items:
- Corded Drill: Your main tool!
- Drill Bits: Assorted sizes and types for different materials (wood, metal, masonry).
- Screwdriver Bits: Phillips, flathead, Torx, etc., if you plan to drive screws.
- Safety Glasses: Absolutely essential to protect your eyes from debris.
- Work Gloves (optional): For a better grip and protection.
- Measuring Tape: To mark where you want to drill.
- Pencil or Marker: To mark your drilling spot.
- Center Punch (optional but recommended for metal/hardwood): To create a small indentation for the drill bit to start in, preventing it from wandering.
- Clamps (optional): To secure your workpiece if needed.
How to Use a Corded Drill: Step-by-Step
Now, let’s get to the action! Follow these steps for safe and effective drilling.
Step 1: Select the Right Drill Bit
This is crucial for a clean hole and to avoid damaging your material or the bit. Consider what you’re drilling into:
- Wood: Use standard twist bits (often black or silver) or brad-point bits (which have a sharp tip to prevent walking).
- Metal: Use HSS (High-Speed Steel) drill bits. They are harder and can withstand the heat generated when drilling metal. A lubricant or cutting oil can help.
- Masonry (brick, concrete, stone): Use masonry bits, which have a carbide tip. You’ll likely need to use the hammer drill function on your drill for these materials.
- Drywall: Most standard twist bits work fine, but be gentle as drywall is soft.
Drill bit sizes are usually marked on the shank (the part that goes into the drill). Choose a size appropriate for your needs – for example, a smaller bit for pilot holes before screwing, or a larger bit for passing a bolt through.
Step 2: Secure the Drill Bit in the Chuck
Most modern corded drills have a keyless chuck. Here’s how to use it:
- Ensure the drill is unplugged before inserting or removing a bit.
- Identify the chuck – it’s the part at the front that grips the bit.
- Tighten the chuck by twisting the chuck sleeve counter-clockwise (away from the drill body) as far as it will go.
- Insert the shank of the drill bit fully into the open jaws of the chuck.
- Loosen the chuck by twisting the chuck sleeve clockwise (towards the drill body) until the jaws grip the bit firmly. You might hear a slight click as it tightens.
- Give the chuck a final twist to ensure it’s snug. It should feel secure and not wobble.
If your drill has a chuck key, you’ll use the key to tighten the chuck by inserting it into the small holes on the chuck and turning it.
Step 3: Set the Drill’s Direction and Speed
Before you plug in, set the drill’s controls:
- Direction: Locate the forward/reverse switch. For drilling or tightening screws, you want it set to forward (usually indicated by an arrow pointing forward or the switch pushed towards the front). For removing screws or backing out a bit, set it to reverse (switch pushed towards the back).
- Speed: Most drills have a variable speed trigger. For starting holes or working with delicate materials, you’ll want to use a slower speed by squeezing the trigger gently. For faster drilling in tougher materials, you can squeeze the trigger further. Some drills also have a speed selector switch (often a button on top) that offers two distinct speed ranges – a lower speed for torque (driving screws) and a higher speed for drilling. Consult your drill’s manual if you’re unsure.
- Mode (if applicable): If your drill has a hammer drill function for masonry, ensure it’s set to the correct mode for the material you’re working with. For wood, plastic, or metal, use the standard drill mode.
Step 4: Prepare Your Workspace and Mark Your Spot
Safety and accuracy start here:
- Clear the area: Make sure you have enough space to work comfortably and that there are no obstructions.
- Secure your workpiece: If you’re drilling into a small piece of material, clamp it securely to a workbench or solid surface. This prevents it from moving and causing an accident or an inaccurate hole.
- Mark the drilling location: Use a pencil or marker to clearly indicate where you want the hole.
- Use a center punch (for metal or hardwood): For harder materials, lightly tap a center punch on your mark with a hammer. This creates a small divot that will guide the tip of your drill bit and prevent it from “walking” or slipping.
Step 5: Position the Drill and Start Drilling
Now it’s time to make that hole!
- Plug in the drill: Ensure the trigger is not being squeezed when you plug it in.
- Grip the drill firmly: Hold the drill with both hands if possible – one on the main handle and the other on the auxiliary handle (if your drill has one) or the front of the drill body. This provides stability and control.
- Position the drill bit: Place the tip of the drill bit directly on your marked spot.
- Start slowly: Squeeze the trigger gently to start the drill at a low speed. Keep the drill perpendicular (straight up and down) to the surface.
- Apply steady pressure: As the bit begins to cut, gradually increase the pressure. Let the drill do the work; don’t force it.
- Maintain control: Keep the drill steady and perpendicular. If you’re drilling a deep hole, you might need to periodically pull the bit out slightly while it’s still spinning to clear away debris (called “clearing the hole”).
- Watch for breakthrough: As you approach the other side of the material, ease up on the pressure to prevent the bit from tearing out the backside.
- Withdraw the bit: Once the hole is complete, keep the drill running at a low speed as you pull the bit straight out of the hole.
Pro Tip: For very smooth holes in wood, you can drill halfway through, then flip the workpiece over and finish drilling from the other side, aligning with the first hole.
Step 6: Driving Screws (Optional)
Many corded drills can also be used as powerful screwdrivers. Here’s how:
- Switch to reverse: Make sure the drill is set to the reverse direction (usually switch pushed towards the back).
- Insert the correct screwdriver bit: Use a bit that matches the head of the screw (e.g., Phillips #2). Ensure it’s securely in the chuck.
- Set the clutch (if available): Some drills have a clutch setting (often a numbered ring around the chuck) that prevents over-tightening and stripping screws. Start with a lower number and increase if needed.
- Start slow: Place the screw head against the surface and gently squeeze the trigger.
- Adjust speed: Once the screw is engaged, you can increase the speed.
- Stop when snug: Release the trigger as soon as the screw is driven to the desired depth. If you have a clutch, it will likely click or slip when the torque limit is reached.
Safety Warning: Always ensure the drill is unplugged when changing bits or screwdriver bits.
Step 7: Cleaning and Maintenance
After you’re done, a little care goes a long way:
- Unplug the drill.
- Remove the drill bit.
- Wipe down the drill with a clean, dry cloth to remove dust and debris.
- Store it properly in its case or a dry, safe place.
Troubleshooting Common Issues
Even with the best intentions, you might run into a snag. Here are a few common problems and solutions:
- Drill bit not spinning: Check if the drill is plugged in and if the forward/reverse switch is set correctly (not in the middle “lock” position if your drill has one). Ensure the trigger isn’t stuck.
- Drill bit slipping: Make sure the drill bit is securely tightened in the chuck. If drilling into hard surfaces, consider using a center punch first.
- Overheating: If drilling continuously, especially in tough materials, give the drill a break. Ensure the ventilation slots are clear of dust. For metal, use lubricant.
- Tearing out the back of the material: Ease up on pressure as you near the other side, or drill halfway from one side and finish from the other.
Safety First! Always Prioritize Safety
Using power tools comes with inherent risks, but following these safety guidelines will keep you protected:
- Wear eye protection: This is non-negotiable. Safety glasses or goggles are essential to protect your eyes from flying debris.
- Keep the work area clean: A tidy workspace reduces tripping hazards and makes it easier to concentrate.
- Secure your workpiece: Never try to hold a small piece of material with your hand while drilling. Use clamps.
- Unplug before changing bits: Always disconnect the power before inserting or removing drill bits or screwdriver bits.
- Keep cords away from the bit: Ensure the power cord doesn’t get tangled in the spinning bit.
- Use both hands: For better control and stability, grip the drill with both hands whenever possible.
- Don’t overreach: Maintain good balance and footing.
- Know your drill: Read your drill’s manual to understand its specific features and safety recommendations.
