8"x3" Expandable Drum Wheel

The Expandable Drum Wheel is a high-quality drum designed for lapidary or metalworking tasks such as sprue removal and contour sanding. It is true-running with no wobble or bounce, which ensures better control during use. The drum is designed to expand when rotated, which allows it to lock the sanding belt in place, providing a secure grip and ensuring that the belt remains in place during use.

One of the key features of the Expandable Drum Wheel is its angled expansion slots that run through the heavy rubber rim. These slots allow the drum to expand when rotated, which locks the sanding belt in place. This makes it easy to change belts in seconds, without having to stop the machine. Simply slip off the old belt and slide on the new one.

The resilient drum surface of the Expandable Drum Wheel is designed to flex to the gemstone's contour, allowing it to quickly remove grinding flats. The convex shape of the drum provides the cutting action necessary to remove scratches, making it an ideal tool for lapidary work.

The Expandable Drum Wheel is sold without a belt, but it expands as the wheel rotates to hold the sanding belt firmly in place. The slightly harder-durometer rubber reduces cupping, which ensures that the drum maintains its shape during use. The maximum recommended speed for the Expandable Drum Wheel is 1800 RPM.

It is important to note that the Expandable Drum Wheel should not be run without belts in place, as this can result in damage to the rubber rim. With its high-quality construction and easy-to-use design, the Expandable Drum Wheel is an essential tool for any lapidary or metalworking workshop. Whether you need to remove grinding flats or contours sanding, this drum provides the control and precision you need to get the job done right.
