Check of setting depth and compress of the drilling dust
Check of setting depth and compress of the drilling dust
Mark the element and check the setting depth and compress the drilling
dust. The element has to fit in the hole until the required embedment
depth.
If it is not possible to compress the dust, remove the dust in the drill hole or
drill deeper.
a) When drilling downward with non-cleaning the required drilling depths can vary due to accumulation of dust in the hole.
