Tech Tips

When using a Skat Blast Cabinet, a variety of dry abrasives can be used, depending on the requirements of the user. Generally, the higher the grit number, the finer the abrasive. The finer the abrasive, the smoother the finish. Coarse-grit abrasives cut fast, but the finish isn't quite as smooth as with fine-grit abrasives.

Most popular abrasives are Glass Beads, First Choice, and Speed Bead for a very fine finish on parts; Skat Magic ™ for a medium finish and faster production. In addition, ground Walnut Shells can be used for special applications. Aluminum Oxide is another popular abrasive for fast cut and long life. All of our abrasive are "virgin" material, which means they have not been processed or reused.

TP Tools Tech TipsWhen abrasive blasting aluminum, brass or softer metals, use a lower air pressure (40-60 psi) for best results. The same applies to carving or etching glass. Hard metals such as fenders, bumpers, etc., can be cleaned best using 50-80 psi. We recommend a cabinet hookup kit for regulating air pressure and collecting moisture effectively.
