How to judge whether the drill bit is installed correctly?

The following are ways to determine if the drill bit is installed correctly:

1. Observe the attachment of the drill bit to the drill rig:

Check that the drill bit is securely attached to the drill rig and shows no signs of looseness or wobbling.

2. Test the movable clearance of the drill bit:

Gently rotate the drill bit to feel its movement clearance on the drill rig. If there is proper movement clearance, it usually indicates that the bit is properly installed.

3. Check screws for tightness:

Ensure that the drill's mounting screws or clamping devices are properly tightened.

4. Perform a test drill:

Carry out a short test drilling operation if it is safe to do so. Observe that the drilling process is normal and free from abnormal vibration or noise.

5. Check drilling results:

After completing the drilling, check that the quality and size of the drilled holes are as expected.
