Benchmark Abrasives 1/2" x 1/2" aluminum oxide spiral bands are a compact, general-purpose abrasive for sanding, deburring, blending, and refining curved, contoured, and hard-to-reach surfaces. Their small 1/2" diameter makes them especially useful for working inside openings and in localized areas where larger sanding products cannot reach effectively.
Made with aluminum oxide abrasive on an X-weight polycotton cloth backing, these bands provide an economical option for everyday surface work. Choose from 36 through 400 grit to move from aggressive material removal to progressively finer scratch refinement using the same spiral band system.

Materials & Applications
Best For
General sanding and surface refinement
Deburring edges and openings
Blending surface imperfections
Removing parting lines
Scratch refinement
Curved and contoured surfaces
Confined and difficult-to-access areas
Suitable Materials:
Cast iron, steel, stainless steel, titanium, nickel, wrought iron, copper, fiberglass, plastic, hard rubber, wood, and stone.
Machine & Drum Compatibility
Use these spiral bands with the matching 1/2" x 1/2" Rubber Expanding Drum, sold separately.
The expanding drum has a 1/4" shank for use with compatible:
Lower grit numbers remove material more aggressively, while progressively finer grits provide more control and a smoother scratch pattern for blending, sanding, and surface refinement.
Safety Tips & Techniques
Make sure the band is fully seated and supported by the correctly sized expanding drum.
Inspect both the band and drum before use and replace damaged or excessively worn components.
Do not allow the abrasive band to extend beyond the supporting drum.
Follow the speed limits and operating instructions for the abrasive band, expanding drum, and power tool. The complete assembly should never exceed the rating of its lowest-rated component.
Wear appropriate eye, hearing, respiratory, and hand protection for the material and application.
Frequently Asked Questions
No. Each package contains 10 abrasive spiral bands. The matching 1/2" x 1/2" Rubber Expanding Drum is sold separately.
The maximum speed is 30,000 RPM when this 1/2" x 1/2" aluminum oxide spiral band is mounted on the matching expanding drum. Always follow the lowest RPM rating shown on the band, drum, and power tool.
Aluminum oxide is the economical general-purpose choice for sanding, deburring, and scratch refinement. Zirconia is better suited to more aggressive stock removal, while ceramic is intended for demanding metal-removal applications. Aluminum oxide also offers the broadest grit range, extending through 400 grit for finer surface refinement.
Yes. Stainless steel is included in the material range for these aluminum oxide spiral bands.
Wet-use approval has not been established for this product. Use them for dry applications unless product-specific wet-use instructions are provided.
No specific finish or mirror finish is guaranteed. The 400-grit band provides finer scratch refinement, but the final appearance depends on the starting surface, work material, abrasive sequence, and any polishing steps that follow.
Mount the band on the matching 1/2" x 1/2" rubber expanding drum, which has a 1/4" shank for compatible die grinders and rotary drills. Make sure the tool accepts a 1/4" shank and stays within the 30,000 RPM maximum for the band-and-drum assembly.
