Abstract: Flap drums (lamellar sanding wheels) are commercial grinding tools used in machining industrial processes such as metal polishing, deburring, and cleaning. This work presents the behaviour of flap drums in metal finishing using a manual hand-held power tool. Different factors such as material interaction, the volume of material removed, life cycle, wear, and aggressiveness of these abrasive tools were studied to formalise the knowledge related to the influence of grit size in this process. For this purpose, performance tests were carried out with two commercial flap drums, both of the same grit and binder, but different particle sizes, using a manual hand-held power tool. The experiments were carried out on samples of stainless and carbon steel and the performance were measured through the relationship between the mass loss of the sample and tool, as well as its surface roughness. The results allowed understanding of the effectiveness of the tools acting on different materials.

Keywords: abrasives; finishing process; hand-held grinding; manual tool; surface roughness; lamellar sanding wheel; flap drum.
