01  M-jump 24 Pack 1 x 30 inch Aluminum Oxide Sanding Belt Kit (Editor’s Choice)

M-jump 24 Pack 1 x 30 inch Aluminum Oxide Sanding Belt Kit

Why it stands out to us

The M-jump 24 Pack 1 x 30-inch Aluminum Oxide Sanding Belts have truly outdone themselves in terms of versatility and durability. The fantastic sharpness of the grains proved to be phenomenal while working on any kind of stuff made of wood, glass, plastic, stone or non-ferrous metals. The anti-static and anti-clogging properties are superb and the load resistance is an added bonus. They come in a sophisticated shade of red and offer an immensely reasonable price.

Our experience with M-jump

  • The belts come as a 24 in one set with a wide range of grit selections. The color is a vibrant yet elegant shade of red and the price is incredibly attractive.
  • These highly versatile belts work on not just non-ferrous metals but also on glass, wood, aluminum, plastic and stone and came as the best all-round choice.
  • We sanded several huge blocks of wooden tabletops without any issue and we were in awe to witness the efficiency and durability. Even the lowest grit was super sharp and worked like magic.
  • We have struggled with polishing stone slabs before. When we brought the M-jump, it took a 180-degree turn. The stone slabs we worked on ended up with super smooth mirror finish using the finest grit and we were beyond happy.
  • Not just big stuff, we also used them for grinding knives and handles and other smaller, delicate things made of non-ferrous metals and they did an impressive job.
  • There was no clogging even when we sanded some oily wood. The anti-static property is splendid as is the load resistance.
  • The seams are super smooth but not thin enough to make the belts break and definitely not thick enough to cause vibrations and awkward bumping sounds when in operation.

What we didn’t like

  • These belts clog if you work on the slightest wet surface.

What could be improved

  • They could be made moisture resistant.

Our recommendations

  • These belts are sharp so start with a gentle application until you get used to them.

Types of Sanding Belts – Choosing the Right Sanding Belt

  • Aluminum Oxide

Known for its durability and versatility, it works on all types of metal and hardwood and is a reddish brown resin bonded abrasive that also has split resistant joints.

  • Silicon Carbide

Suitable for both wet and dry application, this one is perfect for heavier works. They can be applied on marble, glass, fiberglass, plastic, rubber and materials that don’t contain iron.

  • Ceramic Alumina

These belts are fast cutting and instant cooling ones with resin coats. The ceramic sanding belts can be used for aluminum castings and chrome steel. They’re great for aerospace-grade titanium alloys too

  • Zirconia Alumina

The closed-coated, resin-bonded belts are abrasive. Zirconia grains are self-sharpening and really aggressive and so they’re compatible with heavy machines. They’re perfect for scribing hard metal, stainless steel and hardwood.

  • Garnet

Made from a natural mineral called garnet, this belt has the smoothest finishing amongst all the types. This is why it’s the best choice for product finishes.

Best Sanding Belt for Metal – Unlimited  Buying Guide

Best Sanding Belt for Metal - Unlimited  Buying Guide

  • Metal type

Every metal has their own unique properties and depending on these, you need to choose your sanding belt. For example, Silicon Carbide is used on non-ferrous and soft materials such as Aluminum and brass where Zirconia Alumina is used on stainless steel and tough metals.

  • Purpose

The belt type also depends on the kind of operation you plan to do. If you’re blending welds, you’d need Aluminum oxide for most metals but Zirconia Alumina for stainless steel. But the hard to grind ones would require Ceramic Alumina.

  • Grit number

The number of grit determines the belt’s ability to sand smoothly. Grit is the number of particles per square inch and the higher the number, the smoother the result after sanding.

  • Belt life

In several cases, more than one abrasive can meet your requirements. In that case, go with the one that has a longer belt life on average so you don’t need to replace it frequently.

  • Cost

The price range for sanding belts is……. Ceramic Alumina belts cost more than the others but have a longer lifespan.

  • Ask an expert

Consult an abrasive expert if you are an amateur or completely clueless. It would save you time, energy and money.

Tips to Using Sanding Belts

  • Always keep your belt sanders clean, either with metal or with a rubber cleaner stick for sanding.
  • Wear protective glasses, a respirator mask and hearing protection so the dust doesn’t get in your eyes, ears and trachea.
  • Check the roller machine for bumps so you don’t get an uneven sanding.
  • Check the clamp while using a power hand sander or else you’d get non-linear patterns on the surface.
  • Adjust the speed depending on the size of the area you’re working on. Lower speed makes it easy to maneuver where higher speed makes larger areas less time consuming.
  • Mark the areas that you want to sand with a pencil for precision.
  • Always try to sand a surface that is flat.
  • Side to side sanding is harmful for the belt and the machine. So always sand from forward to backward.
