Radial Bristle Disc 1″ 80 Grit Set by HARFINGTON Green

Description

Product Overview

The HARFINGTON radial bristle disc set is engineered for precision polishing across a wide range of materials. Each set includes thirty 1‑inch green discs, split evenly between 80‑grit and 120‑grit options, delivering both coarse and fine abrasive action. The discs feature a flexible rubber‑diamond composite bristle that balances softness with durability, allowing the brush to conform to irregular surfaces while resisting wear. Two mandrel shank sizes—1/8″ and 3/32″—with a 2‑inch shank length ensure compatibility with most rotary tools, die grinders, and drills. Designed for a maximum rotational speed of 30,000 RPM, the discs maintain structural integrity even under high‑speed conditions, making them suitable for demanding industrial and hobbyist applications.

Usage

These discs excel in environments where fine surface preparation is critical. Jewelers can use the 80‑grit discs to remove oxidation and polishing compounds from precious metals, while the 120‑grit discs provide a mirror‑like finish on gemstones and intricate settings. Woodworkers benefit from the gentle yet effective abrasion that smooths veneers, removes old finishes, and prepares surfaces for staining. In metalworking, the discs are ideal for deburring, cleaning weld seams, and polishing cast iron, aluminum, brass, and carbon steel components. The flexible bristles require minimal pressure, reducing the risk of surface scratches and extending the life of both the workpiece and the tool. Adjust the tool speed and apply light pressure to match the material and desired finish.

FAQ

What materials can I safely polish with these discs?

The discs are suitable for a wide range of materials, including precious metals, gemstones, wood veneers, aluminum, brass, bronze, carbon steel, and cast iron. They are especially effective for jewelry finishing, wood surface preparation, and metal deburring.

Can I use these discs on a standard drill?

Yes. The included 1/8″ and 3/32″ mandrels fit most standard drills, die grinders, and rotary tools. Ensure the tool’s speed does not exceed 30,000 RPM and apply light pressure for optimal results.

How do I prevent the bristles from falling off?

Operate the discs within the recommended speed range and avoid excessive pressure. Using the correct mandrel size and maintaining a clean work surface also helps preserve bristle integrity.

Are the discs reusable?

While the discs are designed for long‑lasting performance, they will eventually wear down after extensive use. When the bristles become significantly worn or the abrasive surface is no longer effective, replace the disc to maintain consistent results.

What warranty does HARFINGTON provide?

HARFINGTON offers a one‑year limited warranty covering manufacturing defects. Contact customer support with your purchase details for assistance or replacement options.
