Carbide-tipped angle shanks for removing ceramic, wood and thick epoxy on a ride-on scraper. The angle profile is for ceramic removal and re-scraping thin-set; a straight shank suits hard goods, thick epoxy and elastomeric instead. The carbide tip holds its edge with regular maintenance and resists wear, extending shank life over plain steel. Start with the narrowest shank and work up: a wider shank is not automatically faster. Fits all NFE ride-on scrapers. NFE 7079 series.
