Dico Products 7200039 Nyalox 4 in Fine Flap Brush

Product Description

The DICO PRODUCTS 7200039 is a 4-inch Nyalox fine flap brush designed for sanding, polishing, and surface blending on wood and metal. The bristles are nylon impregnated with aluminum oxide abrasive, which allows the brush to abrade surfaces without gouging or tearing the base material. The 1/4-inch shank mounts directly into a standard drill or rotary tool. This brush is suited for finishing work where surface integrity matters, including rounding cutout edges, smoothing rough wood, and blending transitions on metal workpieces. Woodworkers, metal fabricators, and general tradespeople reach for this tool when a conventional sanding wheel or disc would cause surface damage.

The 7200039 fine flap brush is appropriate for use on unfinished and rough wood surfaces requiring light material removal, polishing, or edge blending. It is also effective on metal for rounding and smoothing cutout edges without leaving deep scratches. The aluminum oxide-impregnated nylon construction makes it a go-to option when working in contoured or irregular areas where flat abrasives cannot maintain consistent contact. It is compatible with any drill or rotary tool accepting a 1/4-inch shank accessory.

Key Features

• Nylon bristles impregnated with aluminum oxide for controlled abrasion without gouging
• 4-inch brush diameter for broad surface coverage on wood and metal
• 1/4-inch shank fits standard drills and rotary tools
• Fine grit rating suited for sanding, polishing, and blending rather than aggressive material removal
• Effective on contoured surfaces, cutout edges, and irregular profiles

Compatibility

Designed for use with any drill or rotary tool equipped with a standard 1/4-inch chuck or collet.

Installation Notes

Secure the 1/4-inch shank firmly in the chuck before operation and confirm the tool is at a complete stop before changing accessories. Keep the brush moving across the workpiece to prevent heat buildup at any single contact point. Wear appropriate eye protection when operating rotary abrasive tools, and ensure the workpiece is clamped or otherwise stabilized.
