Advancements in engineering provide the DUROMAX III rasp with optimal cutting angles when buffing. By altering the cutting angle of the rasp, the entire surface of the rasp can be used. Gone are the days of just 3 rows of blades to do all of the cutting with Matteuzzi buffers. With the DUROMAX III rasp, every tooth on every blade is equally involved in the buffing process. Used in combination with the DUROMAX III blade with B&J’s exclusive ULTANIUM STEEL, the DUROMAX III rasp will provide the user with the lowest cost per buffed tire.

The DUROMAX III CONVEX buffing system is our latest development within the section of convex rasps with 11.5″ Rasp (incl. Refills) resp.  273 mm (excl. Refills) and 6 segments . The DUROMAX III rasp uses the entire width of the convex rasp resulting in:

  •  Even wear of all blades
  •  Longer life
  •  More output of buffed tyres
