Bargain Box of 30 belts - 4 x 21 Sanding Belts - Various Grits

Bargain Box of 30 - 4 inch x 21 inch Sanding Belts - Various Grits

Every grit you could need is included in this bargain box of Klingspor industrial sanding belts.

At this low price, you would think these are cheapo belts that will not hold up under normal sanding pressure. Wrong. These are the same premium quality, heavy cloth-backed, butt joined, resin-coated, aluminum oxide belts we sell individually.

Each box contains 6 sleeves of 5 belts in the following grits:

• 1 sleeve 50-60 coarse
• 2 sleeves 80-100 medium
• 2 sleeves 120-150 med - fine
• 1 sleeve 180-240 fine

These are Premium Abrasive Belts.

They are suitable for use on all ferrous metals, hardwoods, leather, aluminum, brass, bronze, stainless steel, and most alloys. You would use these belts where clogging or loading is a potential problem.

Specifications:

• Aluminum Oxide (blocky, hard grain)
• X-weight (a heavy, stiff Egyptian cotton cloth)
• Open Coat
• Resin to Resin bonded
• Anti-static to resist loading

Aluminum Oxide AO is formed by combining bauxite and other materials by firing them in an electric furnace. The resultant mass is then crushed, and the pieces sifted through successively finer screens to assign a grit size (CAMI grading). When crushed, the resulting pieces are naturally pyramidal in shape. Due to the shape and the strength of the materials used in its making, AO is a very durable grain.

The grain is worn down during use, sanding finer the longer it's used. You can start at 80 grit, and after you've worked the abrasive for a while, you'll be sanding more like 100 or 120 grit. Users take advantage of this characteristic by using the belts on more than one machine or application. For instance, if you have two wide belt machines doing intermediate and finish sanding, respectively, you may use a 120 belt on the first machine to do your intermediate sanding. When the cut for that application is no longer as sharp, the belt can be used for 150-grit application. the cut for that application is no longer sufficient. This ensures you get the most production and the full value for the belt you purchased.

AO is very tough and durable, as stated above, and is used on bare wood, most metals (especially the steels), leather, and a wide variety of other materials. It is a great general-purpose grain and probably the most common grain seen today.
