Aluminium Oxide or Silicon Carbide belts designed to fit on Standard Belt Sanding Machines with a 250 x 750 drum, such as Hummel, Bona etc.
Aluminum oxide is the most common abrasive in woodworking sandpaper. It works well on a number of materials, including bare wood, painted surfaces, and metal. In its most basic form, this furnace-produced mineral does not fracture easily. Instead, it tends to wear down until it becomes too dull to cut efficiently. More expensive forms are friable or semifriable. A number of companies offer more than one grade of aluminum oxide in sandpaper. More expensive, heat-treated versions of the mineral tend to go into higher-priced product lines. With its familiar brown and black flecks, generic aluminum
Silicon carbide is sharper and harder than standard forms of aluminum oxide. It has needle-like grains that resemble shards of broken glass. These hard, sharp grains cut glass, plastic, and metal well under light pressure, but silicon carbide is not a tough mineral. Its elongated shape shears off easily, making it too friable for bare-wood sanding because the abrasive wears down too quickly, according to manufacturers. It is, however, an excellent choice for smoothing a finish between coats and for rubbing out film finishes like lacquer and shellac, because it cuts quickly and produces a uniform scratch pattern. Also, waterproof versions won’t degrade when used with water or oil. For these reasons, it’s also most commonly found in fine grit rather than coarse.
P24, P36 & P40 – Coarse, ideal for the rapid removal of material.
P50 - P80 – Medium, ideal sanding bare wood in preparation for finishing & gentle removal of varnish.
P100 & P120 – Fine, ideal for sanding bare wood in preparation for finishing but not suitable for removing varnish or paint from wood, use for cleaning plaster and water stain from wood.
