Wire Brush Selection

What is the difference between Crimped and Knotted Wire Brushes?

  •  Crimped Wire - Commonly used for a wide variety of applications with irregular surfaces, Crimped Wire Brushes are more flexible, resulting in light to medium duty brushing.  The wire is heat treated and crimped so the individual filaments support eachother.

 

  •  Knotted Wire  - Commonly used for more aggressive applications that require the removal of large burrs, rust, paint and scale, Knotted Wire brushes are made of heat treated straight wire that is twisted.  This twisting of wire results in less flexibility and is well suited for heavy duty applications.

 

Which Knotted Wire Brush is best for my application?

  • Standard Twist - Brushes are twisted and left with a tufted end to allow for more flexibility
  • Cable Twist - Brushes are twisted tightly at the end (no tuft) for more aggressive brushing
  • Stinger Bead Twist -  Most commonly used for weld cleaning, the Stinger Bead Twist has a extremely tight twisted end for very aggressive applications

 

End brushes are only available in Cable Twist

Brushing Pressure

Brushes preform their best when they are cutting on their TIPS.  NEVER USE EXCESSIVE PRESSURE WHEN USING A WIRE BRUSH!  When brushes are placed under pressure there can be an increase in temperature and wire breakage.  This is why it is so important to wear eye protection!  If you are looking for more performance out of your brush, trying decreasing trim length, changing to a more aggressive knotted wire style or increase the surface speed.

 

Brushing Speed

Rule of thumb...run the brush at the highest safe speed.  This will increase cycle times and produce longer brush life.  Never exceed Maximum Safe Speed!!!

Typical Recommendations for Surface Speed Based on Application:

  • Edge Blending - 4,700 - 7,500 SFPM
  • Deburring - 5,400 - 7,500 SFPM
  • Polishing - 6,400 - 8,000 SFPM
  • Weld Cleaning - 7,200 - 10,500 SFPM

 

 

Trim Length Makes a Difference

The shorter the trim length, the more extreme the brushing action will be.  Choose brushes with longer trim length if you are looking for a brush that will follow the contours of the work piece.

Wire Size

The larger the wire diameter, the more aggressive the brush will be.
