Knot Wheel Brushes - Stringer Bead Twist - COMBITWIST® - Carbon Steel Wire

Stringer bead knot wheel brushes are tightly twisted for low flex, high impact brushing action. Designed for root and hot pass weld cleaning in pipe joining applications. Also for general use where a narrow face, aggressive brush is desired for controlled, confined surface contact area.

COMBITWIST® is a variation on existing knot styles in which the knots are alternately twisted to offer superior balance during rotation. This construction style offers a more aggressive and effective brushing solution for cleaning and deburring applications.

Advantages of COMBITWIST®:

  • More aggressive brushing
  • Longer brush life
  • Superior rotational balance
  • Faster stock removal
  • Reduced operator fatigue
  • Better surface finish
