Endless Sanding Belts for Belt Sanders NovoAbrasive

A belt sander is one of the most powerful tools for shaping and finishing, capable of removing material faster than almost any other sander. But the machine is only half the equation. The sanding belt you choose determines the speed, quality, and final result of your work.

This comprehensive guide will explain the anatomy of a sanding belt, how to choose the perfect one for your project, and how to use it to achieve professional-grade results on wood, metal, and more.

What is a Sanding Belt? The Anatomy of Power

A sanding belt is a continuous loop of abrasive material designed to be used on a belt sander. Unlike simple sandpaper, a high-quality belt is a feat of engineering, composed of three critical parts:

1. The Backing: This is the belt's foundation. Novoabrasive uses a durable cloth (fabric) backing, which is far superior to paper. It resists tearing, is more flexible, and can withstand the intense heat and pressure of aggressive sanding, especially around edges.
2. The Abrasive Grain: These are the cutting particles. The belts feature high-quality Aluminum Oxide, a versatile and tough abrasive that is the industry standard for sanding both wood and metal due to its durability and sharp cut.
3. The Joint (or Splice): This is where the two ends of the belt are joined together to form a loop. The quality of this joint is critical. A poorly made joint will bump, chatter, or break prematurely. Novoabrasive belts use a strong, precision-engineered joint for a smooth, consistent sanding experience.

How to Choose the Right Sanding Belt: A 3-Step Decision

Choosing the wrong belt can ruin your workpiece or, at the very least, waste your time. Follow these three steps to make the right choice.

For the vast majority of projects, Aluminum Oxide is the perfect choice. It excels at:

• All types of Wood: From soft pine to hard oak and exotic hardwoods.
• Ferrous & Non-Ferrous Metals: For deburring, cleaning welds, and surface preparation.
• Paints, Varnishes & Fillers: Efficiently strips old finishes and shapes fillers.

"Grit" refers to the number of abrasive particles per square inch. A lower number means fewer, larger particles (coarser), while a higher number means more, smaller particles (finer).

Coarse Grits (P36 - P60):

• Use For: Aggressive stock removal, leveling uneven boards, stripping thick layers of paint, and initial shaping. This is for when you need to remove a lot of material quickly.

Medium Grits (P80 - P120):

• Use For: The workhorse grits for general smoothing after coarse sanding. They remove the scratches left by coarser grits and prepare the wood for finishing. Also great for final shaping and smoothing of metal.

Fine Grits (P150 - P220):

• Use For: Final preparation before applying stains, oils, or the first coat of paint/varnish. This step creates a smooth surface that is ready for finishing.
• Very Fine Grits (P240 and up):
• Use For: Sanding between coats of finish to remove imperfections and ensure a glass-smooth final product. Not typically used for sanding bare wood.

Sanding belts are not one-size-fits-all. You must match the belt's dimensions (width x length) to your machine. Check your belt sander's manual or measure an old belt. Novoabrasive offers a wide range of standard sizes and can produce custom sizes to fit any machine, from small handheld sanders to large industrial floor sanders.

How to Use a Sanding Belt Safely and Effectively

Most sanding belts are directional. Look for a directional arrow printed on the inside of the belt. This arrow must point in the same direction that the belt travels on your sander. Installing it backward can cause the joint to fail and the belt to break.

1. Keep Moving: A belt sander removes material very fast. Never let it rest in one spot, as it will quickly dig a hole. Keep the sander in constant, steady motion.
2. Start Coarse, Finish Fine: Always work your way through the grits sequentially. Don't jump from P60 to P220, as the fine grit won't be able to remove the deep scratches left by the coarse grit.
3. Let the Tool Do the Work: The weight of the sander is usually enough pressure. Pushing down hard will not speed up the work; it will only create uneven results and potentially burn the wood.
4. Clean Your Belt: Use a rubber abrasive cleaning stick to periodically clean the belt. This removes built-up wood dust or resin, restoring the belt's cutting power and extending its life.
