In the last video,
I showed you guys the different types of drill bits.
In this video, I will demonstrate how to drill into concrete.
I will use an impact drill and a hydraulic drill to drill into concrete.
As you can see, it is much slower to use an impact drill to drill into concrete compared to the hydraulic drill.
It took 45 seconds more to use impact drill to drill a hole into the concrete.
However, if you use a hydraulic drill,
It only took about 10-12 seconds
to drill a hole.
Let me give you a tip when using the impact drill.
You can start with a smaller drill bit.
And then use a bigger one, such as the 6.5mm or the 8mm drill bit
to make it easier to drill a hole.
Last tip to share.
When I start drilling, I will press the power button for several times.
To make a concave hole first,
And then drill into it to avoid displacement.
What can we do to prevent drill dust flying everywhere when drilling?
You can take it out the drill bit from time to time when drilling.
The move can prevent the dust
from bursting out at last.
This is the end of the demonstration.
See you next time!
