Weiler 50164 4-1/2" Abrasive Flap Disc Phenolic Backing 5/8"-11 UNC Nut

The Weiler 50164 is a 4-1/2" abrasive flap disc featuring a durable phenolic backing and a convenient 5/8"-11 UNC threaded nut for use with standard right angle grinders. Designed for demanding metalworking environments, this disc delivers consistent stock removal and finishing performance on steel, stainless steel, and other metals.

Key Features:

• 4-1/2" diameter — compatible with standard 4.5" angle grinders
• Phenolic backing — rigid, durable backing that will not scratch the workpiece and is consumable to extend disc life
• 5/8"-11 UNC threaded nut — allows for quick, tool-free disc changes and prevents the disc from sticking to the grinder spindle
• Multiple overlapping abrasive flaps continuously expose fresh grain as the disc wears, maintaining consistent cut rate throughout disc life
• Suitable for grinding, blending, weld cleaning, edge beveling, deburring, and surface finishing applications
• Designed for use on carbon steel, stainless steel, cast iron, and most ferrous metals

Weiler abrasive flap discs are engineered and manufactured to rigorous quality standards, delivering reliable performance and a low cost-of-use for professional fabricators, welders, and metalworkers.
