3M 7000077967 Finishing Flap Brush 3x1.75x0.25in Fine Sc

Product Description

The 3M 7000077967 is a finishing flap brush designed for use with portable rotary tools. It consists of multiple flaps of high-performance finishing web mounted on a 1/4-inch shank, creating a flexible abrasive action suited to surface finishing work. The abrasive mineral is fine-grade silicon carbide, which delivers a consistent decorative scratch pattern for finishing and blending metal and other surfaces. The overall brush dimensions are 3 inches in diameter by 1-3/4 inches in width with a 1/4-inch shank diameter. At 0.18 pounds, the brush is lightweight and easy to maneuver in hand-held tool applications. Metalworkers, fabricators, and finishing technicians are the primary users of this tool.

This flap brush is used in light fabrication, metal finishing, and surface prep applications. It is well suited for applying a uniform decorative scratch pattern on flat or contoured surfaces, blending weld seams, deburring sharp edges, and working on inside diameters where a rigid abrasive would not reach effectively. Its flexible flap construction allows the abrasive web to conform to irregular surfaces during operation, making it a practical choice for both production shops and field service work on portable grinders and die grinders with a 1/4-inch collet.
