Step-by-Step Guide to Change the Drill Bit on a Dewalt DC900
Changing the drill bit on your Dewalt DC900 may seem daunting if you’ve never done it before. However, once you get the hang of it, it’s a straightforward task that takes just a few moments. Follow these steps carefully to ensure a successful bit change.
Step 1: Safety First
Wear your safety goggles and gloves before starting any work on the drill. This step is crucial as it protects you from any debris or accidental slips.
Step 2: Prepare the Hammer Drill
Ensure your Dewalt DC900 is powered off. If you are using a battery model, remove the battery pack to avoid accidental activation during the bit replacement process.
Step 3: Remove the Existing Drill Bit
The next step is to remove the current drill bit. The DC900 features a keyless chuck, which makes this process simpler. Follow these sub-steps:
Unlock the Chuck
- Grasp the chuck with one hand.
- Rotate the chuck counterclockwise to loosen it. You will feel the bit starting to release.
Remove the Bit
- Once sufficiently loosened, pull the bit out of the chuck and set it aside safely.
Step 4: Insert the New Drill Bit
With the old bit removed, it’s time to insert the new one:
Insert the New Bit
- Take your new drill bit and align it with the chuck.
- Insert the bit into the open chuck until it reaches the back of the chuck.
Secure the Bit
- Rotate the chuck clockwise to tighten it securely around the new drill bit.
- Ensure that the bit is firmly in place before proceeding to use the drill.
Step 5: Check the Bit Stability
Before you start using the hammer drill, it’s essential to double-check that the bit is securely locked in place.
- Give the bit a slight tug to ensure it does not move.
- If it feels loose, repeat the tightening process until it is secure.
Step 6: Reinsert the Battery
Once you’ve confirmed that the bit is secure, reinsert the battery pack (if applicable) into the hammer drill. Make sure it clicks into place, indicating proper connection.
Step 7: Test the Drill
To ensure everything is functioning correctly, give the drill a test run:
- Turn the drill on while it’s not in contact with any surface.
- Check for any unusual vibrations or sounds that indicate improper installation.
If everything sounds good, you are ready to begin your project!
Common Drill Bits and Their Uses
When dealing with a hammer drill, it’s crucial to choose the right bit for your project. Using the wrong bit can lead to damage to materials or frustration during your work. Here’s a brief overview of common types of drill bits and their specific applications:
| Type of Drill Bit | Best For | Material |
|---|---|---|
| Twist Drill Bit | General drilling in wood, plastic, and metal | HSS (High-Speed Steel) |

What type of drill bits can I use with the Dewalt DC900 Hammer Drill?
The Dewalt DC900 Hammer Drill is compatible with a variety of drill bits including standard twist drill bits, masonry bits, and specialized bits for metal and wood. When choosing a drill bit, ensure that it is of the correct shank size to fit securely in the chuck of your hammer drill. Most commonly, this drill accepts bits with a 1/2-inch shank.
It’s crucial to select drill bits that match the material you intend to drill. For masonry applications, use a carbide-tipped masonry bit, while for metal, high-speed steel (HSS) bits are preferred. Always check the specifications of your drill bit to confirm compatibility with your Dewalt DC900 to ensure optimal performance and results during use.
How do I remove the drill bit from the Dewalt DC900 Hammer Drill?
To remove the drill bit from your Dewalt DC900 Hammer Drill, begin by ensuring the drill is powered off and unplugged, if corded. If you’re using a battery-powered model, remove the battery pack to prevent accidental activation. Once safely powered down, locate the chuck that holds the drill bit in place.
Using the chuck key or by grasping the chuck with your hand, turn it counterclockwise to loosen it. If your hammer drill features a keyless chuck, you can simply hold the body of the drill and rotate the chuck until it loosens enough to pull the drill bit out. Make sure to grip the chuck firmly and steady the drill body for an easier bit removal process.
How do I install a new drill bit into the Dewalt DC900 Hammer Drill?
To install a new drill bit into your Dewalt DC900 Hammer Drill, first ensure the tool is turned off and unplugged or that the battery is removed. Be sure to select a suitable drill bit based on the material you plan to drill. Once you have your new bit, insert it into the chuck of the hammer drill.
For a keyed chuck, insert the bit fully into the chuck and then secure it in place by turning the chuck key clockwise. If your hammer drill uses a keyless chuck, simply hold the drill body steady and rotate the chuck clockwise until it tightly grips the bit. Always double-check that the bit is securely fastened before operating the drill to avoid accidents during use.
What safety precautions should I take when changing the drill bit?
When changing a drill bit on your Dewalt DC900 Hammer Drill, always prioritize safety. Start by disconnecting the power source by unplugging it or removing the battery pack, eliminating any risk of accidental activation while you are handling the tool.
