Features and Benefits of Wire Brush for Grinder

Brushes are available in a variety of wire types. The proper brush for the application should be selected based on the characteristics of the brush, including wire type. All BlueLine™ packaging is one piece per package.

Knot wire brush for grinders provide high-impact action and offer low to medium flexibility using twisted wire tufts for heavy-duty applications, such as weld cleaning. Knot wire brushes are available in 2-knot configurations.

Crimped wire brush for grinders is general-purpose wire brushes that provide higher flexibility and cleaning action through the use of flexible wire points. They offer a wider work face than knot style and are ideal for light applications such as rust or paint removal.


Flag at end of wire tuft provides additional brush flexibility for irregular surface preparation.	Extremely narrow tufted face is ideal for bead weld preparation	Flexible wire points provide cleaning action for light applications.

Wire Brush for Grinder Size Specifications

The thickness of the brush wire will impact the end result of the workpiece. Fine wire, such as .008 will produce a finer finish and will yield a longer brush life. Thicker wires, such as .014 and .020 or higher, will be more aggressive and will decrease production times.

Wire Brush for Grinder Fill Materials

Carbon steel, the most durable, high-strength fill material available for general-purpose cleaning applications, is suitable for light to heavy-duty cleaning, depending on the wire diameter.

Stainless Steel fill material is suitable on metals such as aluminum and stainless steel when corrosion resistance and non-contaminant brushing actions are desired.

Application Information for Wire Brush for Grinder

Always check warning labels for safety information
Always follow the safety guidelines included with each brush package
Proper application of wire brushes is for the removal of various surface contaminants, not the removal of the base stock material
The power tool determines the size and speed of the brush to be used
Check the R.P.M. rating of the tool to verify that it does not exceed the Maximum Safe Free Speed (M.S.F.S.) of the brush
The slowest speed that will do the job is the most efficient use of the brush. Running at the M.S.F.S. is not necessarily the most efficient speed
The tool shaft must match the arbor hole of the brush
The tips of wire at the end of the brush do the work. Excessive pressure will cause premature wire breakage, reduced brush life, increased heat build-up and rapid dulling

Power Wire Brush for Grinder Safety Requirements

Safety Goggles: Safety goggles, or full face shields worn over safety glasses with side shields, MUST BE WORN by all OPERATORS and OTHERS IN THE AREA OF POWER BRUSH OPERATIONS. Comply with the requirements of ANSI Z87.1 (“Occupational Eye and Face Protection”).
Guards: Keep all machine guards in place.
Speeds: Observe all speed restrictions indicated on the brushes, containers, labels, or printed in pertinent literature. “MSFS” or “MAX.SFS” means Maximum Safe Free Speed (R.P.M.) - spinning free with no work applied. For reasons of safety, the “MSFS/MAX.SFS” should not be exceeded under any circumstances.
Safety Standard: Comply with the safety standards of the American National Standards Institute, ANSI B165.1 and ANSI B165.2 - “Safety Requirements - Power Brushes.”
Protective Equipment: Appropriate protective clothing and equipment (such as full face shield, gloves, respirator, etc.) must be used where a possibility of injury exists that can be prevented by such equipment.
Before starting wire brush for grinder: Use eye protection and safety equipment. Inspect brush for rust, damage, speed limit, etc. If no-load speed marked on the power tool is higher than the brush speed limit, do not mount brush. Inspect and jog machine to assure the brush is mounted properly and securely, machine guards are in place, no vibration, etc. Run machine at operating speed for at least one minute before applying work. DO NOT STAND IN FRONT OF OR IN LINE WITH BRUSH.
