Weiler 50520 Tiger Abrasive Flap Disc, 4-1/2 Dia., 80 Grit (Pack of 10)

The Weiler Tiger type 29 angled-style zirconia alumina abrasive flap disc features an aluminum backing for sturdy reinforcement and a threaded hole for easy attachment to grinding tools. This flap disc is specifically designed to work effectively on curved surfaces. The zirconia alumina abrasive is known for its self-sharpening properties and durability, outperforming traditional aluminum oxide abrasives. This makes it ideal for tasks requiring fast material removal rates and aggressive grinding, such as weld blending, deburring, edge chamfering, and stock removal.

The angled shape of the disc allows for maximum contact with the workpiece, ensuring efficient performance. It is typically used with right-angle grinders at a 15- to 35-degree angle to help dissipate heat during operation. The threaded hole fastening type means that the disc has a female-threaded central hole that can be easily twisted onto a threaded arbor. Abrasive flap discs are constructed from overlapping pieces of coated abrasive attached to a hub, providing a cost-effective solution for grinding and finishing in one step.

Flap discs are coated with adhesive to securely attach the abrasive grains to a backing material made of paper, plastic, or cloth. The grinding action of a flap disc is similar to that of a sanding disc, with the grinding or polishing happening on the face of the disc. They are versatile tools that can be used for a wide range of applications, from shaping parts to achieving a fine finish, depending on the grit size. Lower grit numbers like 40 are coarse and ideal for removing excess material and shaping parts, while higher grit numbers like 400 are finer and produce a smooth surface finish.
