You can deburr with a 120 grit abrasive belt (such as our TZ59 / 120 grit belts) but that will not leave the surface burr free. Our recommendation for a genuine burr free edge are the surface conditioning belts. We have included Coarse (brown) and Medium (maroon) belts.
Both will leave a clean burr free finish with the coarse being approx 150 grit and medium being approx 240 grit finish.
