How to Choose the Right Wire Brush?

Norton wire brushes are the best choice when you need a low impact solution for refining surfaces without removing any base material. High performance brushes will compliment your grinding operations perfectly while bringing comfort and efficiency increase.
Whether you are removing rust, paint, slag, or weld spatter, Norton has the perfect wire brush for you.


Select the Right Wire Brush for the Job

You should consider the four main factors when choosing a wire brush:

1.    Wire type
2.    Wire diameter
3.    Filament configuration

Filament Configuration

Wire cup, wheel and end brushes come with three options for filament configurations and each has its own benefits.

  1. Crimped Wire Brushes
    Individual filaments are supported only by each other, creating extra flexibility. Ideal for work on irregular surfaces, finer surface finishing, and light- to medium-duty contaminant removal.
  2. Standard Twist Knot Wire Brushes
    Made with straight wire filaments twisted together to create more rigid rope- or cable-like pieces. Recommended for more aggressive applications requiring higher impact action and a rougher surface finish.
  3. Stringer Bead Twist Knot Wire Brushes 
    Filaments are more tightly twisted to the end of the knot than standard twist knot brushes, creating a narrower face and highest impact action. Perfect for the most aggressive brushing applications like weld scale cleaning or removing the bead scale.


Trim Length

Trim length equals the amount of usable filament on your wire brush. To choose the right trim length, these best practices will come in handy:

  • Irregular surface - choose longer trim lengths for more flexibility
  • Sever applications - choose shorter, more rigid trim lengths for faster action
