NamPower disc brushes produce maximum burr removal rates and provide an optimum surface finish at the same time. With their unique combination of ceramic and silicon carbide abrasive, these nylon abrasive brushing tools provide reliable, consistent, and cost-effective results for outer diameter (OD) applications.  

Use NamPower nylon abrasive disc brushes to automate secondary operations such as parts deburring, edge blending, and surface finishing.  These professional-grade tools from Brush Research Manufacturing (BRM) are also ideal for surface preparation, parts cleaning, resurfacing, and fine blanking. NamPower disc brushes are ideal for use with today’s production equipment, but which brush tool do you need?

For best results, consider the following factors.

Brush Types

There are two types of NamPower nylon abrasive disc brushes: dot and turbine.

• Dot style tools allow easier entry into small holes and spaces. With their greater flexibility, they’re ideal for lighter-duty deburring and surface finishing.
• Turbine style tools have a high-density fill for medium-duty to heavy-duty deburring. They cut faster and provide short cycle times.

Both types of NamPower disc brushes are built with flexible nylon filaments bonded to a fiber-reinforced thermoplastic base. Plus, BRM supplies lightweight tool holders that put less stress on machine spindles and that support flow-through cooling.

Brush Diameters

NamPower nylon abrasive disc brushes are available in a variety of brush diameters. As a rule, the brush diameter should be larger than the cutting tool that was used to machine the part.

Three smaller-diameter tools are great for harder-to-reach areas.

• 50 mm
• 60 mm
• 80 mm

Three larger-diameter tools are great for surface finishing and deburring larger parts.

• 100 mm
• 125 mm
• 150 mm

Trim Lengths

All NamPower disc brushes are available in two trim lengths: 18-mm and 38-mm. Disc brushes with shorter trim lengths are more aggressive, but less flexible. Disc brushes with longer trim lengths are less aggressive, but more flexible.

Abrasives and Grit Sizes

During brush tool selection, metalworking companies can choose NamPower disc brushes with a unique combination of white ceramic and silicon carbide abrasive. NamPower disc brushes come in four grit sizes: 80, 120, 180, and 320.

To determine which grit size you need, consider the starting surface finish and the amount of material refinement that’s required. As a rule, choose the coarsest grit that will still yield the required surface finish. Then use a finer grit tool, if necessary. Coarse grits are also recommended for heavier burrs, or if a finer finish isn't required.
