Description
Product Overview
The HARFINGTON radial bristle disc set is engineered for precision polishing across a wide range of materials. Each disc measures exactly 1 inch in diameter, providing a compact footprint that fits comfortably on standard rotary tools, die grinders, and drill presses. The green‑colored discs are coated with an 80‑grit rubber‑diamond abrasive matrix, delivering a balanced combination of aggressiveness and finish quality.
Manufactured with a proprietary rubber‑diamond blend, the bristles exhibit superior elasticity, allowing them to conform to irregular surfaces while maintaining consistent contact. This flexibility reduces the risk of surface scratches, a common concern when using harder metal bristles. The discs are mounted on 1/8‑inch mandrels that are 2 inches long, ensuring a secure fit on most tool spindles and providing stability at high rotational speeds.
With a maximum safe operating speed of 30,000 RPM, the set is suitable for high‑speed applications such as jewelry polishing, fine metalwork, and delicate wood finishing. The discs are also designed to withstand the heat generated during prolonged use, thanks to the heat‑resistant properties of the rubber‑diamond composition.
Packaging includes ten individual discs, each individually wrapped to protect the abrasive surface from contamination and damage during shipping. The set is lightweight, weighing only 1.41 ounces in total, making it easy to carry in a tool bag or workshop drawer for on‑the‑go projects.
Usage
These radial bristle discs excel in a variety of polishing scenarios. For jewelers, the 80‑grit level is ideal for removing oxidation and achieving a mirror‑like shine on gold, silver, and platinum pieces without compromising delicate details. In woodworking, the discs can be used to smooth out fine grain patterns, remove surface imperfections, and prepare pieces for final finishing coats.
Metal fabricators will find the discs useful for deburring and polishing cast iron, carbon steel, brass, and bronze components. The flexible bristles adapt to complex geometries, allowing users to reach tight corners and intricate contours that rigid brushes cannot access. The set is also compatible with multi‑purpose rotary tools, making it a versatile addition to any workshop.
When using the discs, it is important to match the tool speed to the material being polished. For softer metals and wood, a lower RPM setting (around 10,000–15,000) helps prevent overheating, while harder alloys can tolerate higher speeds up to the 30,000 RPM limit. Always apply light to moderate pressure; excessive force can cause bristle wear or detachment.
Safety considerations include wearing appropriate eye protection and ensuring the workpiece is securely clamped. Adjust the speed and pressure based on the specific task to avoid material damage or bristle loss. The discs are designed for durability, but regular inspection for wear is recommended to maintain optimal performance.

FAQ
What materials can I safely polish with these discs?
The discs are designed for use on jewelry metals such as gold, silver, and platinum, as well as common industrial metals like brass, bronze, carbon steel, and cast iron. They also work well on hardwoods and soft plastics, making them a versatile tool for many applications.
Can I use these discs on a standard drill?
Yes, the 1/8‑inch mandrel fits standard drill chucks and rotary tool collets. Ensure the drill is set to a speed below the 30,000 RPM maximum and use light pressure to achieve optimal results.
How often should I replace the discs?
Replacement frequency depends on usage intensity and material hardness. For light polishing tasks, a disc may last several hours of continuous use. Inspect the bristles regularly; replace the disc when bristles become frayed or lose their elasticity.
Are the discs safe for delicate surfaces?
Yes, the flexible rubber‑diamond bristles are less likely to cause micro‑abrasions compared to metal bristles. However, always test on a small, inconspicuous area first and adjust speed and pressure accordingly.
What is included in the package?
The set contains ten 1‑inch green discs, each with 80‑grit rubber‑diamond bristles and a 1/8‑inch mandrel. All discs are individually wrapped for protection and come with a brief usage guide.
