The belt is aluminum oxide grain in a nylon web on a reinforced scrim backing built for automated machine tension. Four grades are stocked, Coarse, Medium, Very Fine and Ultra Fine, one belt per order, covering finish stripping and rust removal at one end and a fine pre-buff satin at the other.
- Repeatable directional satin on stainless and aluminum panels, machine-fed rather than hand-finished
- Fits 37-inch wide belt sanders and finishing machines specified for a 60-inch belt
- Four grades from brown Coarse to grey Ultra Fine, sold individually
- Reinforced scrim backing holds tension and tracks on an oscillating head
- Web runs cool and sheds swarf, so the finish stays even through the belt's life
All four grades share the same web and backing. The grain inside the web sets how aggressive the belt is and how fine the finished grain line looks.
- Coarse (40-60 Grit), brown: stripping and cleaning. It takes old paint, powder coat haze, light rust and oxidation off sheet without gouging it the way a coated belt would, and it gives aluminum a bold brushed grain. It removes measurable metal under pressure, so run it at the lightest head setting that does the job.
- Medium (80-120 Grit), maroon: deburring and a medium satin. Behind a 120 grit coated belt it rolls the burr on laser-cut and sheared blanks and leaves an even matte that paint and powder coat adhere to.
- Very Fine (180-240 Grit), blue: the #4-style panel finish. Behind a 180–220 grit coated belt on stainless sheet it produces the long, uniform directional grain that appliance and architectural panels are specified to match.
- Ultra Fine (320-400 Grit), grey: fine satin and pre-buff. Run after Very Fine on aluminum trim, appliance fronts and parts headed for buffing or anodizing. Ultra Fine refines an existing finish and will not remove scratches by itself.
