Krah presents: Mobile hole cutter

We proudly present a new article in our Onlineshop: A mobile hole cutter

When installing sewer systems, holes must often be milled in the pipes in order to be able to insert inlets and outlets. For larger holes, we offer the Manhole Fabrication Center (MF 200), which can mill holes from 90 to 2500mm. The Krah Group has now additionally developed a mobile hole milling machine that can mill hole diameters from 150 to 500mm continuously. This hole cutter can be used for solid wall pipes as well as for profiled pipes. For solid wall pipes, a minimum wall thickness of 10mm is required. The hole miller can be used on pipes with a diameter of DN/ID600mm to DN/ID3000mm.

It is suitable for both fabrication and construction site use, as it is mobile and easy to handle due to its light weight. Another advantage is that it eliminates the need to mark out the diameter, so mistakes can no longer happen, as this is a very precise and demanding job. The result is an exact, circular cut-out that no longer requires any finishing work.

More details about the hole milling machine you can find here.

We have posted a great video on YouTube about how to use the cutter and about the advantages of it. We regularly post videos on Youtube about our products, projects and more. Take a look at the videos and leave a like or subscribe to our channel. We would be very pleased. Enjoy watching!
