hole, run the drill slowly and remove the bit from the hole.
Repeat until hole is cleared
WARNING:
The drill bit, especially the tip, will become very hot
when drilling masonry and concrete. DO NOT touch the bit and
never allow it to come into contact with combustible materials.

breathing protection. Dust from masonry, concrete and similar
substances is harmful and may be toxic.
