Bernardo RAB Notching Machine – for tubes up to 3 mm
The RAB manual pipe notching machine is a professional tool designed to create perfect 90° notches on larger diameter pipes. It is ideal for steel, stainless steel, gas, aluminum, copper, and brass pipes up to 3 mm thick (variable depending on the material). Thanks to the eccentric shaft system, it requires minimal effort, ensuring fast and precise cuts with clean edges that do not require finishing.
Perfect for welding workshops, carpentry shops, and for the construction of tubular structures, the RAB allows you to work with 50 and 61 mm pipes with a single machine. The compact structure, designed for wall mounting, makes it practical and suitable even for small spaces, offering high productivity with a low investment.

Frequently Asked Questions
What is a pipe notching machine and what is it used for?
The Bernardo RA series pipe notching machine creates a circumferential incision (notch/groove) on the pipe, necessary for pressure assembly with press-fit fittings (Pressfit, Viega, Geberit, Mapress). The fitting is pressed into the notch, creating a hermetic, solder-free connection. It is the standard machine in hydraulic-sanitary systems with press-fit fittings.
Which pipe diameters does the Bernardo RAB Notching Machine work with?
Check the specific diameter range in the technical table for the Bernardo RAB Notching Machine. Bernardo RA series notching machines typically cover standard hydraulic-sanitary system diameters (from 15 to 108 mm). Contact Krollit for compatibility with specific diameters.
Does it work with fittings from all manufacturers?
The notch created follows standard ISO 6182/EN 10242 norms. Compatible with Viega, Geberit, Mapress, Aalberts, and other standard press-fit systems. For proprietary systems with specific notching profiles, verify compatibility with the fitting manufacturer.
Are replacement tools (notching wheels) available?
Yes. Notching wheels and original Bernardo spare parts for the RA series are available with 3–5 business day shipping.
Is assistance available?
Original spare parts available with 3–5 business day shipping. Customer support in Italian available.
