Applications
Bands are most typically used for deburring, polishing, blending or surface conditioning. They are effective and extremely economical on both flat and countoured surfaces. They are commonly found in metal and woodworking applications, in addition to plastics, and stone, as well as less industrial applications such as human nail polishing.

Material Specifications
Spiral wound bands are most frequently ordered in aluminum oxide resin bond, but are also available in silicon carbide and zirconia alumina. Because of the requirement for adhering the material to another layer of cotton backing material, only cotton backed material works well in our band-making machinery.

Measurement Specifications
Spiral wound bands are specified with two measurements. They are: 1) the diameter; and 2) the width.

Bands range in diameter from 1/4" to 4". They range in length from 1/4" to 36".

Diameters available: 1/4", 5/16", 3/8", 1/2", 5/8", 7/8", 1", 1-1/4", 1-1/2", 1-3/4", 2", 2-1/4", 2-3/8", 2-1/2", 3", 4"
Widths available: any size from 1/4" to 36"

Grit Availability
Bands are available in a broad range of grits with some limitations. These grits are:
Aluminum Oxide Resin Bond: 400,320,240,220,180,150,120,100,80,60,50,40,36,24
Silicon Carbide Resin Bond: 120, 100, 80, 60, 50
Zirconia Alumina: 80, 60, 50, 40, 36
    Note: Other material specifications and grits may be available on request.

Due to the thickness and inflexibility of the material in coarser grits, some small diameter bands cannot be made in coarser grits. Grit availability per diameter for bands is shown below.

Expanding Rubber Drums
A rubber expanding drum contains a tightening nut which has a reverse thread. Once a band is placed on the drum and the nut is tightened, the diameter of the rubber drum expands, allowing it to firmly hold the band in place. Because of the reverse thread, it self-tightens the band while running.

An expanding rubber drum is specified by three measurements. They are:

1) the diameter, which corresponds to the diameter of the band.
2) the width, corresponding to the width of the band.
3) the shank diameter, which is generally 1/8" to 1/4" in the smaller diameter drums, or 1/4" to 3/8" in the larger diameter drums.

Below is a listing of expanding rubber drums currently available.
