The Benchmark Abrasives 3/8" x 13" zirconia sanding belt is a Made in USA abrasive belt built for steel grinding, shaping, and fabrication in narrow or hard-to-reach areas. Its compact 3/8" width makes it well suited for file sanders where controlled stock removal and access around edges, contours, and tight spaces matter.
Zirconia alumina is a strong choice when the job calls for more aggressive metal removal than a general-purpose aluminum oxide belt. Available in 24, 36, 40, 60, and 80 grit, this belt is geared toward coarse grinding, shaping, edge cleanup, and surface preparation.

Materials & Applications
Best For: Steel grinding and shaping on narrow file sanders and compact belt-sanding equipment.
Common applications include:
Steel stock removal.
Weld and edge cleanup.
Shaping and contour work.
Deburring.
Surface preparation.
Removing surface imperfections.
Fabrication and maintenance work.
Grinding in narrow or difficult-to-reach areas.
Machine Compatibility
Designed for machines using a 3/8" x 13" sanding belt, including portable file sanders, compact belt sanders, and similar equipment.
Fits machines designed for 3/8" x 13" sanding belts, including:
Milwaukee® 2483-20 M12 FUEL Bandfile
Astro Pneumatic® 3036 File Sander
Always confirm your machine's required belt dimensions, configuration, and operating-speed requirements before use.
Tips for Better Belt Performance
Match the grit to the amount of stock removal and surface refinement required.
Allow the zirconia abrasive to do the cutting rather than using excessive pressure.
Keep the belt tracking correctly and inspect it before use.
If using the belt wet, confirm the machine and application are approved for wet operation.
Always use the guards and PPE required for your machine and application.
Frequently Asked Questions
It is designed primarily for steel grinding, shaping, stock removal, edge cleanup, and fabrication work.
This belt is designed for machines that use 3/8" x 13" sanding belts. Examples include Milwaukee® 2483-20 and Astro Pneumatic® 3036. Other machines using this belt size may also be compatible. Check your exact model and installed setup before ordering, and follow the machine and belt speed requirements.
Use 24–36 grit for very coarse stock removal, 40–60 grit for coarse grinding and shaping, and 80 grit for medium sanding and refinement.
The belt is listed for wet or dry use, but wet sanding should only be performed when the machine and application are approved for it.
Yes. The belt is bi-directional, but follow your machine's required running direction.
Choose zirconia when the application is centered on steel stock removal, grinding, and shaping. Aluminum oxide is the more general-purpose option for everyday wood and metal sanding across a broader grit range.
