Superior Abrasives A006780 Spiral Band Expander Drum

Product Description

The SUPERIOR ABRASIVES A006780 is a spiral band expander drum designed to hold abrasive spiral bands for deburring, blending, and finishing work on metal, wood, and composite surfaces. The drum measures 1 inch in diameter and 1 inch wide, with a 1/4 inch shank that fits standard die grinders, drill presses, and rotary tools. It is rated to 10,000 RPM, making it suitable for high-speed finishing applications. Machinists, fabricators, and tool-and-die technicians install this type of expander drum when consistent surface preparation or edge finishing is required across production or repair workflows.

This expander drum is used in metalworking shops, fabrication facilities, and maintenance environments where spiral abrasive bands need a secure, stable mounting point. The 1/4 inch shank diameter makes it compatible with the collet systems found on most standard die grinders and handheld rotary tools. It is appropriate for both bench-mounted and handheld applications where access to tight bores, contoured surfaces, or internal radii is needed. The 1.5 inch drum length provides adequate contact surface for mounting abrasive bands of corresponding width.

Compatibility

Designed as an OEM-style expander drum for use with spiral abrasive bands sized to fit a 1 inch diameter by 1 inch wide drum, mounted via a 1/4 inch shank in standard die grinders or rotary tools.

Installation Notes

Installation is performed by machinists or fabricators using standard collet-equipped die grinders or drill presses. Ensure the tool is powered off and unplugged before mounting or removing the drum. Confirm the abrasive spiral band is fully seated and expanded on the drum before operating. Never exceed the 10,000 RPM maximum speed rating, and always wear appropriate eye protection and gloves during operation.
