Brush Wire Size
To ensure maximum brush life, select the finest (smallest) wire size that will perform your operation. Finer diameters of wire or filaments present more cutting tips per square inch to your work piece than larger diameter wires or filaments. Also, larger diameter wires fatigue more rapidly than smaller diameters, which shortens brush life.
Should a more aggressive brushing action be desired, several factors should be considered before using a larger wire size:
- A higher operating speed (not to exceed MSFS),
- A more densely filled brush
- A shorter trim length
- Another type of brush
