For metalworkers tackling burrs, rough edges, and hard-to-reach surfaces, the United Abrasives 38344 Tapered Cartridge Roll provides controlled abrasive action in channels, fillets, recesses, and confined areas. Featuring a 3/4" base diameter, 2" length, and 60 grit premium aluminum oxide grain, this cartridge roll supports deburring, blending, and surface finishing on ferrous and non-ferrous metals, including stainless steel and high-tensile steel. Its tapered profile allows access to recessed surfaces where larger abrasive wheels or discs may be difficult to position.
The United Abrasives 38344 features multi-layer, self-dressing construction that exposes fresh abrasive grain as the outer layers wear away, helping maintain cutting action throughout use. The 3/16" arbor hole accommodates a correctly sized cartridge roll mandrel for use with a suitable die grinder, while the 18,000 maximum RPM rating establishes the upper operating speed limit for safe tool selection. Supplied in a box of 100 rolls, this configuration supports workshops and fabrication operations that regularly perform detailed metal finishing and flash removal.
