Available Grit Options for Our 2 1/2" x 16" Sanding Belts

One of the keys to a successful project is using the right abrasive grit. A sanding belt that removes material too aggressively can leave scratches, while a grit that's too fine may make it difficult to remove material efficiently. By choosing the appropriate grit for your application, you can improve productivity and achieve a more consistent finish.

Red Label Abrasives offers 2 1/2" x 16" sanding belts in grit options ranging from 24 grit to 1000 grit. This broad selection allows you to progress through multiple sanding stages using belts that fit the same machine. Whether you're removing large amounts of material or preparing a surface for polishing, there's a grit option suited to the task.

Coarse Grits: 24, 36, 40, and 60

Coarse grits are intended for aggressive material removal and shaping applications. These belts, which remove stock rapidly, are commonly used during the early stages of a project, when appearance is less important than material removal rate. If you're working with rough lumber, damaged surfaces, heavy rust, or thick coatings, coarse grits can help reduce labor and speed up production. For example:

• Woodworkers frequently use coarse grits to flatten uneven boards, shape components, and remove saw marks. 
• Metalworkers rely on these grits for weld cleanup, rust removal, edge preparation, and fabrication work. 
• Knife makers use coarse belts during profiling and bevel grinding, where large amounts of steel must be removed efficiently.

While coarse grits produce visible scratch patterns, they set the stage for more refinement. Moving progressively through finer grits helps refine the surface and prepare it for finishing.

Medium Grits: 80, 100, 120, and 150

Medium grits strike a balance between material removal and surface refinement. These belts are commonly used after initial shaping has been completed and before final finishing begins. They remove scratches left behind by coarser abrasives while continuing to shape and smooth the workpiece.

• In woodworking applications, medium grits help prepare surfaces for stain, paint, or clear finishes. They remove milling marks, refine edges, and smooth transitions between surfaces.
• For metalworking projects, medium grits are frequently used to blend welds, refine fabrication work, and prepare surfaces for coatings.
• Knife makers regularly use medium-grit belts to refine bevels and remove scratches created during earlier grinding stages. 

These grits help create a cleaner appearance while maintaining efficient stock removal.

Fine Grits: 180, 220, and 320

Fine-grit sanding belts are intended for finish preparation and surface refinement. At this stage, the goal shifts from shaping and stock removal to creating a cleaner, smoother appearance. Fine grits help eliminate visible scratches and prepare surfaces for paints, stains, sealers, and other finishes.

• Woodworkers frequently use 180-grit and 220-grit abrasives before applying finish coats. These grits help produce smooth surfaces while maintaining good finish adhesion. For projects that demand further refinement, 320-grit belts can further improve surface quality before finishing.
• In metalworking applications, fine grits help create more uniform finishes and improve the appearance of fabricated parts. They are also useful for blending sanding marks and preparing surfaces for polishing sequences.

Ultra-Fine Grits: 400, 600, 800, and 1000

Ultra-fine grits are used when appearance and surface quality are top priorities. These belts produce refined scratch patterns and help prepare materials for polishing, buffing, or high-gloss finishes. They are commonly used during the final stages of sanding after lower grits have already removed imperfections and shaped the workpiece.

• Metalworkers use ultra-fine grits to improve surface finishes on stainless steel, aluminum, and other metals. 
• Knife makers frequently progress through these grits before polishing blades to achieve clean, uniform finishes. 
• Woodworkers may use these abrasives for specialty finishing applications where a highly refined surface is required.

These grits are also popular when working with acrylics, resins, fiberglass, plastics, and other materials that benefit from controlled surface refinement before polishing. When paired with proper sanding progression, ultra-fine belts can help create exceptionally clean finishes with minimal visible scratching.

How to Choose the Right Abrasive Material

Different materials are engineered for different applications, which is why selecting the right abrasive is just as important as choosing the right grit. Red Label Abrasives offers 2 1/2" x 16" sanding belts in closed coat aluminum oxide, open coat aluminum oxide, and silicon carbide to help you match the abrasive to the material you're working with.

Closed Coat Aluminum Oxide Sanding Belts

Closed coat aluminum oxide is one of the most widely used abrasives in woodworking and metalworking. In a closed coat configuration, abrasive grains cover nearly the entire surface of the belt. This dense grain pattern places more cutting points in contact with the workpiece, allowing for rapid material removal and long service life.

These belts perform well on: 

• Hardwoods
• Carbon steel
• Tool steel and many other materials

Woodworkers use closed coat aluminum oxide belts when flattening boards, shaping furniture components, and preparing surfaces for finishing. Metal fabricators also rely on them for removing material quickly while maintaining consistent cutting action.

The toughness of aluminum oxide also helps the abrasive resist premature wear. As the belt is used, fractured abrasive grains expose fresh cutting edges that continue removing material throughout the life of the belt. This helps maintain productivity and reduces the frequency of belt changes.

Open Coat Aluminum Oxide Sanding Belts

Open coat aluminum oxide belts have less abrasive grain coverage than closed coat products. The spacing between grains creates channels that allow dust, wood fibers, paint residue, and other debris to escape during sanding. This design reduces loading and helps maintain cutting performance when working with materials that generate large amounts of debris.

These belts are particularly useful when sanding pine, cedar, fir, and other softwoods. They are also a strong choice for paint removal, finish removal, and applications involving resin-rich materials. Because debris has additional room to clear from the abrasive surface, the belt remains cleaner for longer periods and continues cutting without becoming clogged as quickly.

Many woodworkers prefer open coat aluminum oxide belts for projects that involve soft or resinous lumber because belt loading can reduce productivity and shorten abrasive life. By minimizing buildup on the abrasive surface, open coat belts help maintain a cleaner sanding action and support more consistent results.

Silicon Carbide Sanding Belts

Silicon carbide is known for its sharp cutting characteristics and ability to produce refined surface finishes. The abrasive grains are harder and sharper than aluminum oxide, allowing them to cut aggressively while leaving a more uniform scratch pattern. This makes silicon carbide a strong choice for finishing applications and materials that benefit from cleaner surface refinement.

These belts are frequently used on: 

• Stainless steel
• Aluminum
• Brass
• Bronze
• Fiberglass
• Plastic
• Resin
• Glass
• Stone
• Composite materials

They are also commonly selected for pre-polishing sanding stages because the abrasive creates a more consistent finish than many general-purpose sanding products.

Knife makers and metalworkers frequently use silicon carbide abrasives when preparing surfaces for buffing or mirror finishing. Fabricators working with non-ferrous metals also value the clean scratch patterns produced by silicon carbide during finishing operations. For projects where surface appearance is a top priority, silicon carbide sanding belts provide the cutting action and finish quality needed to achieve professional results.

Cloth Backing for Demanding Applications

Red Label Abrasives' 2 1/2" x 16" sanding belts feature cloth backing built to withstand demanding shop conditions and repeated use. The material resists tearing, stretching, and premature wear, making it a strong choice for projects involving extended sanding sessions or aggressive stock removal.

Advantages include:

• Heat Resistance:Friction between the abrasive and the workpiece creates heat that can stress both the belt and the material being sanded. Cloth backing provides the strength needed to withstand these conditions. This is especially important during grinding and shaping applications where pressure levels are higher, and temperatures can increase rapidly.
• Better Belt Tracking:A stable backing helps the belt run properly on the machine, reducing unwanted movement that can affect sanding performance and surface finish quality. Better belt stability can also contribute to more predictable material removal and improved control during detailed work.

How to Select the Right Sanding Belt

Abrasive type, grit size, and backing construction all influence performance. By selecting the appropriate combination, you can improve material removal, achieve a cleaner finish, and get more value from each belt.

For Aggressive Stock Removal

If your project involves aggressive stock removal, start with a coarse grit. Lower grit numbers contain larger abrasive particles that remove material quickly. As the project progresses, move to finer grits to reduce scratch patterns and improve surface quality. Skipping too many grit levels can make it harder to remove scratches left behind by earlier sanding stages, which may increase sanding time.

What Material Are You Working With?

The material being sanded should also influence your abrasive selection. Closed coat aluminum oxide belts are an excellent choice for general woodworking, metalworking, and fabrication tasks. Their dense grain coverage provides strong cutting action and long abrasive life. Open coat aluminum oxide belts are better suited for softwoods, painted surfaces, and materials that generate large amounts of sanding debris. Silicon carbide belts are ideal for finishing operations, polishing preparation, fiberglass, plastics, stainless steel, and non-ferrous metals.

Are There Contoured Surfaces?

Backing type can also affect results. Standard cloth-backed belts provide durability and stability for demanding sanding applications. If your project involves contours, rounded edges, or detailed shaping work, Flex backing can help the abrasive maintain better contact with the workpiece.
