The Weiler Tiger type 29 angled-style zirconia alumina abrasive flap disc has an aluminum backing for rigid reinforcement and a threaded hole for attachment to grinding tools, and works well on curved surfaces. The zirconia alumina abrasive is self-sharpening and more durable than aluminum oxide, which makes it suitable for fast material removal rates and aggressive grinding. Applications include weld blending, deburring, deflashing, edge chamfering, stock removal, and grinding and finishing in one step. The disc has an angled shape for maximum workpiece contact and is commonly used with right-angle grinders at a 15- to 35-degree angle to dissipate heat. Threaded hole fastening type indicates a disc with a female-threaded central hole that twists onto a threaded arbor.
