Description
Product Overview
The Cubitron Scotch-Brite SR Radial Bristle Disc is a premium abrasive solution designed for industrial sealant removal. Each disc measures 3 x 3/8 inches and is constructed from a blend of durable plastic abrasive particles and a specialized bristle matrix. This combination provides a gentle yet effective cutting action that lifts sealant without compromising the underlying material. The pack includes ten discs, each weighing 2.12 ounces, and is engineered to fit both straight and right‑angle grinders using 3M #990 or #991 mandrels (sold separately). The discs are lightweight, portable, and ideal for reaching confined or hard‑to‑access areas where traditional sealant‑removing compounds fall short.
Usage
These radial bristle discs excel in a variety of industrial settings, from aerospace maintenance bays to automotive repair shops and heavy‑equipment refurbishment facilities. They are intended for professional use only, targeting technicians who need to remove sealant, gasket material, or similar residues from metal, composite, or plastic surfaces. The discs can be mounted on a straight grinder for broad surface work or on a right‑angle grinder for tight corners and intricate geometries. Their small diameter and flexible design enable precise control, reducing the risk of over‑grinding and ensuring the integrity of the part remains intact.

FAQ
Can these discs be used on non‑metal surfaces?
Yes, the radial bristle design is safe for use on composite, plastic, and painted surfaces, provided the grinder speed is set within the recommended range.

The discs require a 3M #990 or #991 mandrel, which are sold separately. These mandrels are standard for most industrial grinders.
How often should the discs be replaced?
Replacement frequency depends on usage intensity and material hardness. For typical sealant‑removal tasks, a full pack of ten discs will last several hundred minutes of operation.
Are the discs suitable for removing cured sealant?
