Power Brushes

Heavy-Duty Power Brushes for Industrial Surface Preparation

Benchmark Abrasives power brushes deliver industrial-strength performance for rust removal, weld cleaning, deburring, and surface prep. Built with high-quality wire filaments and durable construction, these brushes handle demanding metalworking tasks while providing consistent, reliable results.

What Are Power Brushes?

Power brushes are wire brushes mounted to power tools such as angle grinders, drills, die grinders, and bench grinders. Designed for aggressive surface preparation and controlled material removal, they are essential tools for metalworking, fabrication, and maintenance applications.

A power brush functions as a wire brush for rust removal, stripping corrosion, paint, oxidation, and mill scale from metal surfaces quickly and efficiently. They are also widely used as a wire brush for metal surface prep and as a wire brush for weld cleaning, removing slag, spatter, and discoloration without damaging the base material.

Available in multiple configurations and wire materials, power brushes allow operators to match the aggressiveness of the brush to the hardness of the workpiece and the finish required.

Stringer Bead Wire Wheels

Stringer bead wire wheels are designed for precise weld cleaning along narrow seams and beads. Their thin, knot-twisted wire construction removes slag, spatter, and oxidation without damaging surrounding metal.

Mounted Wire Wheels (Drill-Mounted)

Mounted wire wheels attach to drills or die grinders and are ideal for light cleaning, deburring, and rust removal in tight or hard-to-reach areas. They operate at lower RPMs, offering greater control for detailed work.

Nylon Power Brushes 

Nylon power brushes use abrasive-filled filaments to clean and polish surfaces without aggressive metal removal. They’re ideal for delicate materials, non-sparking applications, and situations where surface protection matters.

How Do Power Brushes Work?

Each power brush contains tightly packed wire filaments that act as individual cutting tools. As the brush rotates at high speed, the wires remove surface contaminants and refine the finish.

Performance is influenced by:

• Brush wire composition

• Brush diameter and construction

• Brush speed and positioning

• The hardness and type of workpiece material
  

Power brushes can be used with machinery like angle grinders, die grinders, drills, and bench grinders, or applied manually depending on the job.

Types of Power Brushes and Their Uses

Power brushes come in multiple configurations to match specific cleaning, deburring, or finishing needs:

Tube Brushes

Ideal for cleaning bores, cylinders, and internal surfaces. Available in nylon, carbon steel, and stainless steel for everything from manual cleaning to heavy-duty power tool use.

Wheel Brushes

Used for blending, cleaning, and polishing. Made from crimped or knot-twisted wires in brass, stainless steel, or carbon steel. Knot wheels excel at removing scale, weld spatter, and heavy contamination.

End Brushes

Designed for precision cleaning in hard-to-reach areas such as corners, holes, and recesses. Available in crimped and knot configurations.

Cup Brushes

Perfect for large-surface cleaning, heavy rust removal, and aggressive surface prep. Their broad contact area makes them ideal for angle grinders.

Power Brush Filament Materials

The wire material determines durability, aggressiveness, and the types of metals each brush is best suited for.

Carbon Steel Wire

The most common and versatile choice. Benchmark Abrasives uses heat-treated, high-tensile carbon steel for maximum cutting power and long life.

Stainless Steel Wire

Recommended for brushing stainless steel or non-ferrous metals to prevent contamination and corrosion.

Nylon Filaments

A durable, flexible synthetic option ideal for polishing and cleaning sensitive surfaces. Resistant to heat, chemicals, and abrasion.

FAQs About Power Brushes

Which power brush should I use for rust removal?

For heavy rust removal, a knotted wire wheel or knotted cup brush provides the aggressiveness needed to remove corrosion quickly and efficiently.

What’s the best wire brush for cleaning weld beads?

A stringer bead wire wheel is the best choice for cleaning weld beads. Its narrow profile allows precise cleaning along weld seams without damaging surrounding metal.

Can I use a wire cup brush on my angle grinder?

Yes, you can use a wire cup brush on an angle grinder as long as the arbor size and RPM rating of the brush match your grinder’s specifications.

Should I use carbon steel or stainless wire?

Use stainless steel wire on stainless or non-ferrous metals. Avoid using carbon steel wire on stainless steel, as it can cause surface contamination and corrosion.

What’s the maximum RPM for a wire brush?

The maximum RPM for a wire brush depends on its diameter and construction. Always check the manufacturer’s labeling on the brush before use.

When should I use a nylon power brush instead of metal wire?

Nylon power brushes are best for delicate cleaning, polishing, deburring, and non-sparking applications, especially on softer metals or coated surfaces where aggressive wire could cause damage.
