8"x3" Expandable Drum Wheel

Expanding drums are a highly effective tool for achieving smooth, polished stone surfaces. These drums feature a soft, pliable rubber material that expands during rotation, providing a secure grip on sanding or polishing belts. This design allows for quick and easy belt changes, simply by sliding the belts off the drum.

At low speeds, the flexible drum surface can conform to curved surfaces, ensuring optimal contact with the workpiece. This characteristic makes expanding drums ideal for finishing intricate stone shapes. Conversely, when used at high speeds, the drum surface behaves more like a hard rubber grinding wheel, enabling efficient material removal.

Expanding drums are compatible with a variety of abrasive belts, including diamond and silicon carbide belts. These belts offer different grit levels and cutting properties, allowing you to achieve the desired finish for your specific application.

The heavy-duty machined hubs of expanding drums are typically supplied with bushings to accommodate various arbor sizes, including 1", 3/4", 5/8", and 1/2". This versatility ensures compatibility with a wide range of power tools and equipment.

In summary, expanding drums are a valuable asset for stone fabricators and finishers. Their ability to produce high-quality finishes, coupled with their ease of use and versatility, make them a popular choice for a variety of stoneworking tasks.
