Technical Information

  • The twist knot wire allows:
    • Long working life
    • High removal capacity
    • Possibility of working at high speed
  • Designed for use on portable machines (angle grinders).
  • Appropriate for brushing large surfaces with a high removal capacity.
  • Patented nut design and multi-thread are available in two versions:
    • One is available in 5/8”-11 & M14 x 2.0 thread combination and the other is available in the M10 x 1.25 & M10 x 1.50 thread combination.
    • This unique nut design is easier to tighten and loosen on and off angle grinders.  The nut design also covers a greater surface area, which gives the nut greater strength against resistance, torque, and “brush back off.”

Metal Ring Information
A metal bridle is a standard feature on the JAZ 4” and 5” twist knot cup brush.  This serves a dual purpose:

  • Prevents the cup brush from flaring out excessively, which allows for more aggressive surface cutting by having more wires contacting the surface. 
  • When the wire is worn to the metal knock-off ring, the ring can be removed with a hammer and screwdriver.  Removing the ring exposes more trim length and allows for an additional 30% working life of the brush.
