Weiler 50519 Tiger Premium Flap Disc, 60 Grit, 4-1/2 inch

Weiler Tiger type 29 angled-style zirconia alumina abrasive flap disc features an aluminum backing for rigid reinforcement and a threaded hole for easy attachment to grinding tools. This type of flap disc is specifically designed to work well on curved surfaces, providing maximum workpiece contact. The zirconia alumina abrasive is self-sharpening, making it more durable than aluminum oxide. This durability allows for fast material removal rates and aggressive grinding, making it ideal for weld blending, deburring, deflashing, edge chamfering, stock removal, and grinding and finishing in one step.

The angled shape of the disc allows for better contact with the workpiece, and it is commonly used with right-angle grinders at a 15- to 35-degree angle to help dissipate heat. The threaded hole fastening type indicates that the disc has a female-threaded central hole that twists onto a threaded arbor. Abrasive flap discs are made from overlapping pieces of coated abrasive attached to a hub, which helps reduce finishing time and cost by combining grinding and finishing into one step.

Flap discs are coated with adhesive to attach the abrasive grains to a backing of paper, plastic, or cloth. The action of a flap disc is similar to that of a sanding disc, with the grinding or polishing occurring on the face of the disc. They can be used for a variety of applications, from shaping a part to fine finishing, depending on the grit size. Lower grit numbers like 40 are coarse and are used for removing excess material and shaping parts, while higher grit numbers like 400 are fine and help create a smooth surface finish.
