- Insert the chuck key into the chuck key holes on the drill chuck. Turn the key counter - clockwise to loosen the chuck jaws. As you turn the key, the jaws will gradually open.
- Once the jaws are open enough, carefully pull out the old drill bit from the chuck. Be cautious as the drill bit may be hot or have sharp edges.
Step 3: Clean the Drill Chuck
After removing the old drill bit, use a cleaning brush to remove any dirt, dust, or debris from the drill chuck. This will ensure a proper fit for the new drill bit and prevent any damage to the chuck or the new bit. Pay special attention to the inside of the chuck jaws and the areas where the drill bit makes contact.


Step 4: Select the New Drill Bit
Choose a drill bit that is compatible with the YT28 Rock Drill. Consider the type of rock or material you will be drilling, as different drill bits are designed for different applications. For example, if you are drilling hard rock, a carbide - tipped drill bit may be more suitable.
Step 5: Install the New Drill Bit
- Insert the shank of the new drill bit into the drill chuck. Make sure the drill bit is centered and straight within the chuck.
- Insert the chuck key into the chuck key holes again. This time, turn the key clockwise to tighten the chuck jaws around the drill bit. Tighten the jaws firmly, but be careful not to over - tighten as this may damage the drill bit or the chuck.
- Check the tightness of the drill bit by gently pulling on it. It should not move or come loose.
Step 6: Test the New Drill Bit
Before using the YT28 Rock Drill with the new drill bit, it is advisable to perform a quick test. Turn on the power supply (or air supply if it is pneumatic) and let the drill run at a low speed for a few seconds. Observe the operation of the drill and make sure the new drill bit is working properly.
Common Issues and Troubleshooting
