Industrial power brushes are a type of tool that allows for surface treatment via intense brushing action

Industrial power brushes are a type of tool that allows for surface treatment via intense brushing action. They are typically used for blending, polishing and contaminant removal. They are available in various shapes, sizes and brush filament fabrications.
Examples include carbon steel, stainless steel, brass and nylon. They can be fabricated in single or double spiral brush arrangements.

Cup Brushes
Designed for use with a right angle grinder, die grinder or other power tool, wire cup brushes remove rust, paint and scale. They also polish and deburr. Models are available to clean a wide variety of flat or curved surfaces and parts, including welded joints, weld bead areas, pipe bevels and castings.
Knotted wire cup brushes have a cup-shaped base that holds bristles in a ring to provide large surface area of contact. They are used for more aggressive cleaning and deburring than crimped wire models.
Different knot styles, wire gauges and trim lengths allow users to fine-tune brush performance for specific applications. Brush fill options include carbon and stainless steel wire, brass and bronze for nonsparking applications, abrasive nylon 6-6 or 6-12 and horsehair.

End Brushes
Industrial brushes in wheel, end, and cup styles are used for a variety of applications, including weld blending, surface finishing, and cleaning. They are frequently used to remove paint, scale, rust, and contamination from parts and workpieces.
The most common metal abrasive brush filaments are carbon, stainless steel, and brass wires, which come in a variety of diameter widths. Depending on the application, these abrasive brush filaments may be twisted or knotted to form different types of power brushes.
The end brushes have a narrow brush shape and are typically made of highly resistant crimped wire, allowing for deburring in tight spaces, corners, and slots. They are usually designed with a 1/4 inch shank to be used with a drill or air tool. The crimped wire design is typically used for light to medium duty jobs.

Rotary Cylinder Brushes
Cylinder brushes are used in many applications to sweep, clean, polish or deburr surfaces. They offer a broader brush face than cup or end brushes and can be found in industrial settings including conveyors, manufacturing plants, food processing facilities and airports.
Cylindrical brushes come in a variety of shapes and sizes with various core and filament materials depending on the application. Popular cylinder brush filaments include polyester PBT (which offers better flick action than nylon), Tampico fibers, which are made from vegetable fibers of the Agave lechuguilla plant, and bronze and brass wire, which offer superior high-temperature oxidation resistance.
Like wheel brushes, cylinder brushes can have bristles stapled, glued or knotted onto a core in straight or staggered patterns. They can also be fabricated with a mix of metal bristles, such as crimped or knotted carbon, stainless steel and brass, which are useful for applications requiring static reduction, higher operating RPMs and electrical conductivity.

Double Spiral Brushes
Knot wheels consist of metal filaments that are conformed together into a wheel shape and twisted to form an effective, powerful brush. They are generally used for heavy, abrasive cleaning tasks such as removing weld slag and scale, according to experts.
The tensile strength and diameter of wire filament plays an important role in the effectiveness of these brushes. Typically, longer filaments are less aggressive and more flexible than shorter ones.
Double stem and double spiral brushes are designed for use with power tools for heavy duty cleaning and deburring. They are available in a variety of brush diameters to fit different applications including honing, thread chasing and cleaning blind holes and internal surfaces. They can be fabricated using carbon, stainless steel, brass, and nylon brush fill materials.

Tube Brushes
Tube brushes, also known as flue brush or cylinder brushes, are used for cleaning internal applications like cylinders and bores. They are available with either single- or double-stem wire and have twisted or spiral bristles that come in a variety of diameters.
These brushes reduce the costs associated with cleaning and maintaining equipment by removing crusty buildup and contaminants, such as rust, scale, and oxidation. They also remove welds, and deburr and finish drilled holes and threads.
They are often used in the HVAC industry by technicians to prepare and maintain heating, venting and air conditioning systems. They are also used in laboratory environments to clean a wide variety of glassware and vessels, including test tubes, vials, and Erlenmeyer flasks. They can be made in a variety of sizes and materials and can be customized for manual or power application.
