The drilling hole blow out pumb from bolting.eu is an indispensable tool. This is because the manual blow out pumb is essential for the first and second steps of borehole cleaning.
Firstly, it is used to blow out the drilling hole for the first time immediately after drilling. Hence its name. Secondly, the drill hole is blown out again after the hole brush has been used at least twice. This ensures that there is no more drilling dust in the hole.
Properties drilling hole blow out pumb
- Weight: approx. 330 grams
- Size: 30 x 8 x 8 cm
- Functionality
- High blowing pressure reliably transports drilling dust out of the drilling hole
- Sealing ring on the cylinder increases service life
Functionality
Using the drilling hole blow out pumb is very simple. First, simply insert the tube into the drilling hole. The air is then sucked in using the built-in pump mechanism and pressed out of the cylinder. The air is pressed into the hole and efficiently transports the drilling dust out of the hole.

The video below shows you just how important the “blow out pumb” step is. It is clear to see. A poorly cleaned drilling hole reduces the holding values of chemical anchors enormously. Consequently, cleaning the drill hole in alpine sports is particularly important when using injection mortar of particular importance.
Suitable brushes
In addition to the drilling hole blow out pumb , you also need the corresponding hole brush or Fischer brush set. Regardless of whether you want to set up a climbing route with expansion bolt . Or you want to set up a climbing route with glue in bolt. The drilling holes must be clean. Especially when glue in bolt setting, the drilling hole must be completely free of drilling dust. Holes for expansion bolt are not so sensitive. However, we clearly recommend cleaning these as well.
Areas of application drilling hole blow out pumb
If you want to drill in concrete in compliance with the approval, you need a blow out pumb. We strongly recommend it for the following applications in alpine sports:
- Climbing area construction
- Climbing area rebolting
- Climbing area maintenance
- Via ferrata construction
Use the blow out pumb and document the use accordingly in the building documentation!
