Superior Abrasives A006805 Spiral Band Expander Drum

Product Description

The SUPERIOR ABRASIVES A006805 is a spiral band expander drum designed to hold abrasive sanding sleeves for grinding, blending, and finishing operations on metal, wood, and composite materials. The drum measures 2 inches in diameter and 1 inch in width, with a 1/4 inch shank diameter for mounting in a standard drill press, handheld drill, or die grinder. Rated at a maximum of 11,000 RPM, this expander wheel expands outward when spinning to grip the sanding sleeve firmly, preventing slippage during use. Machinists, fabricators, and finishing technicians rely on spiral band drums for contoured surface work and deburring tasks.

This expander drum is suited for use in fabrication shops, maintenance facilities, and production environments where abrasive sleeve sanding is part of the workflow. It is typically used in handheld rotary tools, benchtop drill presses, or similar equipment with a 1/4 inch collet or chuck. The 1 inch drum width accommodates standard sanding sleeves of matching size for efficient material removal on inside curves, slots, and irregular profiles.

Key Features

• Spiral band expander wheel design grips abrasive sleeves securely during rotation
• 2 inch drum diameter and 1 inch width fit standard matching abrasive sleeves
• 1/4 inch shank diameter compatible with common drill chucks and collets

Compatibility

Designed as an OEM-style expander drum for use with abrasive sanding sleeves sized to fit a 2 inch diameter by 1 inch wide drum with a 1/4 inch shank mount.

Installation Notes

Installation is performed by machinists or finishing technicians using standard hand tools. Before mounting, ensure the rotary tool or drill press is powered off and unplugged. Insert the 1/4 inch shank into the appropriate collet or chuck and tighten securely before sliding the abrasive sleeve over the drum. Do not exceed the 11,000 RPM maximum speed rating, and always inspect the sleeve and drum for wear or damage before each use.
