Internal Brushes

Osborn ATB Helituf™ Internal Brushes are designed with high-quality nylon filament embedded with durable Silicon Carbide and unique helix design to provide efficient internal surface cleaning and deburring action. Helituf™ brushes should only be used with suitable holders and fully chucked.

Designed tool for extending Osborn internal brushes into those hard to reach places. Features a locking set screw for easy use and superior gripping power so the brush won’t come out during operation.

Osborn’s ATB Situft™ Internal Brushes feature premium-quality abrasive nylon filaments to provide efficient, aggressive abrasive action across a wide range of internal cleaning and finishing operations. Situft™ brushes should be used only with suitable holders.

Featuring spiral-mounted nylon filaments with abrasive Silicon Carbide grit, Osborn ATB™ Tube Brushes offer extra cutting and cleaning action without sacrificing brush life. Brush can be mounted onto a portable or stationary tool for efficient operation.

Osborn ATB™ Heavy Duty Internal Deburring Brushes feature a higher filament content and are specifically designed to efficiently tackle the toughest tasks. Flexible crimped nylon filaments feature durable Silicon Carbide abrasive and are manufactured with a helical shape, providing optimal performance in both rotational directions with excellent part conformability.

Featuring rectangular nylon strips impregnated with tough Aluminum Oxide, Osborn’s ATB™ Rectangular Filament Internal Brush provides a highly efficient side-sweeping action across the surface. Filament shape applies approximately 18 times more abrasive contact than traditional round filaments. Aluminum Oxide ensures a superior finish and prolonged brush life.

Premium high-performance nylon filaments with choice of embedded abrasives offer ultra-fine deburring and cleaning of holes produced by micro drilling. Designed for uniform brushing action that will not alter the hole diameter or surface finish. Can be used manually or on power tools. Constructed for longevity and use on applications requiring absolute precision. Note: brush selected should be ~0.015 inches larger than hole.

Osborn’s small diameter ATB™ Novoflex Tools are designed with round, abrasive beads fastened to the end of flexible nylon filaments sized to address smaller applications such as brake cylinders, hydraulics and valve guides. This self-centering tool will conform to the bore surface to provide a consistent, even surface finish over the life of the tool.

Designed with round, abrasive beads fastened to the end of flexible nylon filaments, Osborn ATB™ Novoflex flexible honing tools are ideal for a variety of bore cleaning tasks. Tools create crosshatch pattern for improved oil retention and increased efficiency, and will even provide an edge break not possible with conventional honing stones.

The longer brush length of Osborn’s heavy duty ATB™ Novoflex Tool tackles tough honing projects with efficiency. Silicon Carbide abrasive beads are fastened to durable nylon filaments to allow the tool to conform to the bore surface. Flexible filaments are engineered to provide the correct pressure to create an ideal hone over the life of the tool.
