Analysis Of Wedge Anchor Installation Method
Rotary drilling: Drilling without impact, for hollow bricks and building materials with low strength to avoid drilling too much or breaking the structure in the hollow bricks.
Impact drilling: Rotating with high frequency of light impact, used for solid construction materials with tight structure.
Hammer drilling: Rotating with a heavy impact at the bottom frequency, for solid construction materials with a tight structure.
Diamond or hollow bit drilling: mainly used for larger drilling diameters or dense substrate reinforcement.
Diamond or hollow bit drilling: mainly used for larger drilling diameters or dense substrate reinforcement.
Here is another ingenious one for impact-free drilling: carbide bits are sharpened like steel bits to make them sharp, which makes drilling a bit faster. There are also special wall drill bits available for common use
