Weiler 31317 Vortec Pro Flap Disc 4.5 in 120Z Type 29

Product Description

The WEILER 31317 is a Type 29 angled abrasive flap disc designed for aggressive material removal at a practical cost. Built under the Vortec Pro line, this disc measures 4.5 inches in diameter and features a 5/8 inch-11 arbor hole for direct mounting on standard angle grinders. The 120Z abrasive grain delivers a fine cut rate suited for finishing passes, blending welds, and surface preparation on metal workpieces. The angled flap configuration increases surface contact and promotes consistent stock removal. An aluminum backing plate provides stability and support throughout the disc life. Manufactured in the USA.

This flap disc is suited for use on angle grinders in metal fabrication, welding shops, and general maintenance settings. The Type 29 angled style is commonly chosen for work on flat and contoured surfaces where a consistent finish is required. It is appropriate for both residential maintenance tasks and light commercial fabrication. The 120Z grit makes it a finishing-stage tool rather than a heavy-stock-removal disc, fitting applications where surface quality matters as much as cut rate.
