Yes, you can absolutely put drill bits in a cordless screwdriver! It’s a common question, and the answer is a resounding yes. A cordless screwdriver is essentially a small, low-power drill designed for driving screws, but with the right drill bits, it can easily handle drilling small holes. We’ll walk you through how to do it safely and effectively.
Ever looked at your trusty cordless screwdriver and wondered if it could do more than just drive screws? Maybe you’ve got a small project, like hanging a picture frame or assembling some furniture, and you need to drill a pilot hole or a small hole for a wall anchor. You might be thinking, “Can I put a drill bit in my cordless screwdriver?” It’s a question many DIYers have, and the answer is a simple, encouraging “Yes!” Your cordless screwdriver, while often specialized for screws, is built on the same fundamental principles as a drill. With the correct accessories, it can definitely tackle light-duty drilling tasks. Don’t let it gather dust; let’s unlock its full potential! We’ll cover everything you need to know, from choosing the right bits to making sure you don’t overdo it.
Why the Confusion? Understanding Your Tools
It’s easy to get confused because cordless screwdrivers and cordless drills often look similar. Both have a trigger, a chuck (the part that holds the bit), and a battery. However, they’re typically designed with different strengths in mind.
Cordless Screwdrivers: These are generally smaller, lighter, and have lower torque (twisting power) and speed than drills. Their primary purpose is to drive screws efficiently without stripping them or damaging the material. They often have a clutch mechanism to prevent over-driving.
Cordless Drills: These are usually more powerful, with higher torque and speed settings. They are built to handle a wider range of tasks, including drilling through various materials and driving larger fasteners.
The confusion arises because many modern cordless screwdrivers are quite capable, and the line between them and a compact drill can be blurry. The key takeaway is that while a cordless screwdriver can drill, it’s best suited for lighter drilling tasks in softer materials.
Can I Put a Drill Bit in a Cordless Screwdriver? The Simple Answer
Yes, you can put a drill bit in a cordless screwdriver, provided the drill bit has a compatible shank (the part that goes into the chuck) and your screwdriver’s chuck can securely grip it. Most modern cordless screwdrivers have a standard three-jaw chuck that accepts common round or hexagonal shanks found on drill bits.
The crucial point is understanding the limitations. A cordless screwdriver isn’t designed for heavy-duty drilling. Trying to drill through thick metal, concrete, or hardwoods can strain the tool, overheat the motor, drain the battery quickly, or even damage the chuck.
Choosing the Right Drill Bits for Your Cordless Screwdriver
Not all drill bits are created equal, and choosing the right ones for your cordless screwdriver is key to success and tool longevity.
Types of Drill Bits
For most tasks you’ll undertake with a cordless screwdriver, you’ll be looking at these common types of drill bits:
HSS (High-Speed Steel) Twist Drill Bits: These are the workhorses for drilling into wood, plastic, and metal. They are versatile and widely available. For your cordless screwdriver, focus on smaller diameters (e.g., 1/16 inch to 1/4 inch).
Brad-Point Drill Bits: These are specifically designed for wood. They have a sharp point that “cams” into the wood, preventing the bit from wandering when you start drilling. This is excellent for precise pilot holes.
Spade Bits (or Paddle Bits): While generally for larger holes, very small spade bits might be usable in some screwdrivers for wood, but they require more torque. Stick to twist bits for ease of use.
Hex Shank Drill Bits: Many drill bits designed for impact drivers and cordless drills come with a 1/4-inch hex shank. These are often a perfect fit for the chucks on many cordless screwdrivers and offer excellent grip.
Shank Types
The shank is the part of the drill bit that inserts into the tool’s chuck.
Round Shank: The most common type. Your cordless screwdriver’s chuck should grip this securely.
Hex Shank (1/4-inch): Very common on bits designed for cordless tools. These provide a strong, non-slip grip.
Reduced Shank: Some larger bits have their shank ground down to fit smaller chucks.
Important Note: Always ensure the drill bit’s shank diameter is smaller than or equal to the maximum capacity of your cordless screwdriver’s chuck. Most cordless screwdrivers have chucks that open to about 3/8 inch (10mm) or 1/2 inch (13mm).
How to Insert a Drill Bit into a Cordless Screwdriver: A Step-by-Step Guide
It’s straightforward, but doing it correctly ensures the bit stays put and you don’t damage anything.
1. Ensure the Tool is Off: Always make sure your cordless screwdriver is turned off and the battery is removed or disengaged before inserting or removing any bit. Safety first!
2. Open the Chuck: Locate the chuck at the front of your screwdriver. It usually consists of two or three metal jaws. Grip the rear part of the chuck firmly and twist the front part counter-clockwise. This will cause the jaws to retract, opening up the space in the center.
3. Insert the Drill Bit: Take your chosen drill bit and insert the shank end into the opened chuck. Push it in as far as it will comfortably go.
4. Close the Chuck: While holding the drill bit steady with one hand, grip the front of the chuck and twist it clockwise. You’ll feel and hear the jaws close, gripping the drill bit shank tightly.
5. Test the Grip: Gently try to wiggle the drill bit. It should feel secure and not move within the chuck. If it feels loose, repeat steps 2-4, ensuring you tighten the chuck firmly. Some chucks have a ratcheting mechanism that clicks when fully tightened, providing a very secure hold.
6. Re-engage Battery: Once the bit is securely in place, you can re-insert the battery.
Using Your Cordless Screwdriver for Drilling: Best Practices
Now that you’ve got a drill bit in your screwdriver, here’s how to use it effectively and safely for drilling tasks.
Setting Up for Success
Select the Right Bit: As discussed, choose the appropriate bit for your material and hole size.
Check Your Material: Is it wood, drywall, plastic, or thin metal? Your cordless screwdriver is best for softer materials and smaller holes.
Mark Your Spot: Use a pencil or a center punch (for metal or hard surfaces) to mark exactly where you want to drill. This prevents the bit from wandering.
Consider a Pilot Hole: For slightly larger holes or harder materials, drilling a smaller pilot hole first can make the main drilling much easier and cleaner.
The Drilling Process
1. Position the Tip: Place the tip of the drill bit directly on your marked spot.
2. Apply Gentle Pressure: Hold the screwdriver perpendicular to the surface. Apply steady, gentle downward pressure. Don’t force it.
3. Start Slowly: Squeeze the trigger gently to start the drill at a slow speed. This helps the bit bite into the material without slipping.
4. Increase Speed Gradually: Once the bit has started a small indentation, you can gradually increase the speed by squeezing the trigger further.
5. Maintain Perpendicularity: Try to keep the drill as straight and perpendicular to the surface as possible. Angled drilling can stress the bit, the chuck, and the motor.
6. Clear Debris: Periodically pull the drill bit partially out of the hole while it’s still spinning slowly. This helps clear away sawdust or debris, preventing the bit from binding and allowing for smoother drilling.
7. Don’t Overheat: If the screwdriver or the bit feels excessively hot, stop and let it cool down. This is a sign you might be pushing the tool too hard.
8. Smooth Exit: As you near the end of the hole, ease off the pressure slightly to prevent the bit from tearing through the back of the material, especially in wood.
When to Use Your Cordless Screwdriver for Drilling (and When Not To)
Your cordless screwdriver is a versatile tool, but knowing its limits is crucial.
Ideal Scenarios:
Drilling Pilot Holes: For screws that are slightly too large for the material or to prevent wood splitting.
Hanging Light Items: Drilling small holes in drywall or plaster for screws or anchors for pictures, small shelves, or lightweight decor.
Assembling Furniture: Creating small holes for dowels or fasteners in particleboard, MDF, or softwoods.
Working with Plastics: Drilling holes in plastic components for small bolts or wires.
Small DIY Projects: Any task requiring holes up to about 1/4 inch in soft materials.
Situations to Avoid:
Thick or Hard Materials: Drilling through thick metal, concrete, brick, or dense hardwoods.
Large Diameter Holes: Attempting to drill holes much larger than 1/4 inch, especially if they require significant force.
Continuous Heavy Use: If a task involves drilling many holes in a row, especially in tougher materials, a dedicated cordless drill is a better choice.
Masonry: Cordless screwdrivers lack the hammer function found in hammer drills, which is essential for drilling into concrete or brick.
Understanding Torque and Speed Settings
Many cordless screwdrivers have adjustable torque settings (often indicated by a numbered collar near the chuck) and sometimes speed settings.
Torque Settings: These control how much twisting force the tool applies before it stops (or slips the clutch). For drilling, you generally want to set the torque to a higher number than you would for driving screws. This allows the drill bit to spin more freely. Some tools have a dedicated “drill” mode that bypasses the clutch entirely.
Speed Settings: If your screwdriver has speed settings (often a switch on top), use the higher speed for drilling. Lower speeds are typically for driving screws with more control.
Example Torque/Speed Settings for Drilling:
| Material | Recommended Torque Setting (if applicable) | Recommended Speed Setting | Notes |
| :————– | :—————————————– | :———————— | :——————————————- |
| Drywall | Low to Medium | High | Pilot holes for anchors |
| Softwood (Pine) | Medium | High | Pilot holes, small diameter holes |
| Plywood | Medium | High | Pilot holes |
| Plastic | Low to Medium | High | Small holes for wires, fasteners |
| Thin Metal (e.g., sheet metal) | Medium to High | High | Use cutting fluid; pilot holes are essential |
Always consult your tool’s manual for specific recommendations.
Battery Life Considerations
Drilling generally consumes more power than driving screws. Here’s how to maximize your battery life when drilling:
Use the Right Bit Size: Smaller bits require less power.
Don’t Force It: Let the drill bit do the work. Forcing the tool drains the battery faster.
Clear the Hole: Regularly clearing debris prevents the bit from binding, which saves battery.
Keep Batteries Charged: Always start with a fully charged battery.
Consider a Spare: For larger projects, having a spare battery can be a lifesaver.
When to Upgrade: Recognizing the Limits
While your cordless screwdriver is capable of drilling, there comes a point where a dedicated cordless drill will make your life much easier and your projects more successful. If you find yourself:
Frequently needing to drill holes larger than 1/4 inch.
Often working with harder materials like oak, maple, or metal.
Needing to drill multiple holes in succession for extended periods.
* Wishing for more power and control.
…then it might be time to consider investing in a good quality cordless drill. They are designed for these tasks and will perform significantly better. You can find excellent entry-level cordless drills that are still very affordable. For instance, brands like DeWalt, Milwaukee, Makita, and Ryobi all offer a range of drills suitable for DIYers. Many come with a drill-only mode and higher torque settings that are perfect for drilling.
