The Benchmark Abrasives 4" x 24" zirconia sanding belt is a Made in USA abrasive belt designed for steel grinding, shaping, deburring, and stock removal on portable belt sanders. Its wide 4" working surface is well suited for larger-area metal sanding where fast coverage and aggressive material removal are important.
Zirconia alumina is a strong choice when the job calls for more aggressive steel removal than a general-purpose aluminum oxide belt. Available in 24, 36, 40, 60, and 80 grit, this belt is geared toward heavy sanding, shaping, edge cleanup, and surface preparation.

Materials & Applications
Best For: Steel grinding and shaping with portable 4" x 24" belt sanders.
Common applications include:
Steel stock removal
Surface grinding
Weld and edge cleanup
Deburring
Shaping and material removal
Surface preparation
Removing surface imperfections
General fabrication and maintenance work
Machine Compatibility
Designed for machines using a 4" x 24" sanding belt, including portable belt sanders and similar equipment used for larger-area metal sanding.
Fits machines designed for 4" x 24" sanding belts, including:
Makita® 9403 Belt Sander
Makita® 9404 Belt 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.
Keep the sander moving as appropriate to help produce a more consistent surface.
Allow the zirconia abrasive to do the cutting rather than applying 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, deburring, and surface preparation.
This belt is designed for machines that use 4" x 24" sanding belts. Examples include Makita® 9403 and 9404. 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. The Makita® 9403 and 9404 are for dry operation, even when the belt itself supports wet use.
Use 24–36 grit for very coarse stock removal, 40–60 grit for coarse grinding and shaping, and 80 grit for medium sanding, blending, and refinement.
The belt is designed 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, shaping, and fabrication. Aluminum oxide is the more general-purpose option for everyday wood and metal sanding across a broader grit range.
