Frequently Asked Questions
What is a tube notcher and what is it used for?
The Bernardo MRA-Pro tube notcher removes internal and external burrs from cut tubes, creating a precise chamfer that facilitates assembly with fittings, welding, and sealing. This operation is necessary after every tube cut with a band saw, miter saw, or manual tube cutter — without deburring, fittings do not insert correctly and welds show defects.
What tube diameters can the MRA-Pro process?
Check the diameter range in the MRA-Pro technical data table. The Bernardo MRA series typically covers standard diameters for plumbing, heating, and industrial systems. Contact Krollit for compatibility with specific diameters. Customer support in Italian available.
Does it work on stainless steel, copper, and aluminum tubes?
Yes. With appropriate tools, the MRA-Pro processes steel, stainless steel, copper, brass, and aluminum. For stainless steel, use specific tools for stainless steel — those for mild steel wear out quickly and can contaminate the surface. Tools and spare parts available with 3–5 business days shipping.
Is the electric MRA-Pro version faster than the manual one?
Significantly. The motorized electric version allows deburring in a few seconds compared to 1–2 minutes for the manual version, with a more uniform result and without fatigue. For series production, the electric version is indispensable.
Are spare parts available?
Original spare parts available with 3–5 business days shipping. Customer support in Italian available.
