The Foredom® expanding drum is excellent for lapidary use as well as many metalworking applications such as sprue removal and contour sanding. Designed to be used on a right-side spindle (lettering faces away from the motor), the drum expands as the wheel rotates, holding the belt firmly in place (see "Caution" notes below). A slightly cushioned sanding surface makes smoothing and shaping of contoured surfaces quick and easy. Built-in bushing accommodates most tapered spindles, providing quick and easy attachment and fast belt changes.
Max. speed: 8,000rpm
• CAUTION! This wheel should NEVER be run without a belt in place on it; doing so can 1) cause the wheel to become unbalanced so that it cannot function properly and/or 2) cause the rubber to over-expand violently, causing injury to persons in its vicinity and damage to equipment.
• The lettering on the this wheel should be outward-facing when it is properly installed; if the lettering is not facing away from the motor, it should be removed and re-installed properly.
• This drum is not suitable for flex shaft systems.
