How to Select Wheel Brushes



Brush Research Manufacturing (BRM) supplies wheel brushes for a wide variety of surface finishing applications, including cleaning, polishing, blending, deburring, and surface preparation. These BRM power brushes are available in many different types and sizes, and feature brush filaments made of brass, carbon steel, stainless steel, nylon, abrasive nylon, or Tampico.

When selecting wheel brushes, brush type is an especially important consideration. There are two main types of BRM wire wheels: knotted and crimped. Abrasive nylon wheels provide a safe, non-reactive alternative to wire wheel brushes, and come in several different abrasive types and grit selections. Tampico wheels and mandrel-mounted industrial brushes are also available.

Wire Wheel Brushes
Knotted wire wheel brushes are durable, flexible brush tools that provide heavy-duty brushing action. Designed for aggressive cutting and cleaning applications, these power brushes have tufts that reduce fatigue by absorbing vibrations. BRM supplies knotted wire wheels with either standard or cable twists in medium and wide face sizes. Stringer bead brushes have a very narrow width face, and are used to prepare the surfaces of small channels and grooves prior to pipe welding.  

Crimped wire wheel brushes are made of oil-tempered, crimped metal wire and used in applications ranging from light deburring and pipe cleaning to edge blending and rust removal. These BRM power brushes are designated for standard-duty, heavy-duty, or super-duty use, and are specified by face width, filament material, and filament size. Fast and efficient, crimped wire wheels provide a uniform brushing action and can have brass, carbon steel, or stainless steel filaments.

Abrasive Nylon Wheels and Nylon Wheel Brushes
Abrasive nylon wheel brushes offer a safe, non-reactive alternative to wire brushes for the deburring of extrusion cut-offs. Available in diameters ranging from 6” to 14”, abrasive nylon wheels feature flexible nylon filaments with aluminum oxide (AO) or silicon carbide (SC) abrasives in a wide range of grits. These industrial brushes are suitable for use with most pedestal grinders, and remove burrs and improve finish without disturbing the underlying surface.

Nylon wheel brushes are designed for light-duty deburring, cleaning, polishing, and surface finishing applications. Made with high-quality 6-12 nylon filaments, these brushing tools offer abrasive resistance, excellent fatigue life, and chemical resistance to most solvents. Nylon wheels can be used dry or with a lubricant, and are available in a variety of diameters for controlled brushing action.

Tampico Wheel Brushes and Mandrel Mounted Wheels
Tampico wheel brushes feature tough, oil and heat resistant filaments derived from a cactus plant that grows in northern Mexico. These natural fiber wheels are designed for wet or dry applications, including polishing chrome and deburring decorative surfaces. For tough applications, Tampico power brushes are often used with a grease-type abrasive stick or polishing compounds.

Mandrel mounted wheel brushes have integral shafts or shanks that eliminate the need for a separate adaptor when using them with handheld power tools such as electric drills, or production equipment such as automated CNC machinery. Mandrel mounted wheels can have abrasive nylon or steel filaments, and feature a flared or standard face. Flared brush tools allow for finishing on undercuts, shoulders, and hard-to-reach areas.
