The Benchmark Abrasives 1" x 42" aluminum oxide sanding belt is a Made in USA, general-purpose abrasive belt for sanding, shaping, and surface preparation on wood and metal. The 1" width offers a useful balance of surface coverage and control for benchtop sanders, compact grinders, fabrication work, and smaller knife-making setups.
Aluminum oxide delivers dependable everyday sanding performance at an economical price point. With grits from aggressive 24 through fine 400, this belt covers material removal, shaping, blending, scratch refinement, and finer finishing without changing abrasive families.
*Wet use also depends on whether the machine and application are approved for wet operation.
Product Features
Aluminum oxide grain for general-purpose sanding on wood and metal
X-weight polycotton cloth backing for support during sanding
Closed-coat construction provides dense abrasive coverage

Tips for Better Belt Performance
Use these aluminum oxide belts for dry sanding only.
Allow the abrasive to do the cutting rather than applying excessive pressure.
Keep the belt tracking correctly and inspect it before use.
A sanding belt cleaning stick can help remove accumulated material from the abrasive surface when appropriate.
Always use the guards and PPE required for your machine and application.
Frequently Asked Questions
No. Benchmark recommends these aluminum oxide sanding belts for dry use only.
This belt is designed for machines that use 1" x 42" sanding belts. Examples include Kalamazoo® 1SM, 1SMS and BG142, JET® J-4002, and RIKON® 50-144. 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.
Yes. The 1" width provides good control for shaping, detail sanding, handle work, and other smaller knife-shop applications. Dedicated 2" x 72" grinders remain the more common format for larger-scale blade grinding.
Use 24–60 grit for heavier removal and shaping. Use 80–180 grit for smoothing and scratch refinement. Use 220–400 grit for finer finish preparation.
Yes. The belt is bi-directional, but follow your machine’s required running direction.
Aluminum oxide is the general-purpose choice for everyday wood and metal sanding. For applications focused on heavier steel stock removal or more demanding grinding, consider the appropriate Benchmark Abrasives zirconia or ceramic belt for the material and machine.
