Freud DCF045050S04G Fiber Disc 4.5 in 50 Grit 4 Pack

Product Description

The FREUD DCF045050S04G is a 4-pack of 4.5-inch, 50-grit fiber discs engineered for aggressive material removal and extended sanding life. The abrasive surface uses a premium aluminum oxide blend that cuts faster and lasts longer than standard aluminum oxide discs. Each disc is built for high-friction, high-heat grinding applications where consistent stock removal matters. These discs are a staple for metal fabricators, welders, and pipefitters who need reliable performance across repeated passes without premature breakdown of the abrasive layer.

These fiber discs are suited for use on angle grinders in both residential and commercial metal fabrication settings. Primary applications include removing stock material, grinding welds flush, blending surface transitions, and smoothing weld beads on structural steel, pipe, and sheet metal. The 50-grit rating places these discs in the coarse range, making them appropriate for initial material removal and weld grinding rather than finish work. A rubber or hard backup pad is required for proper disc support during use.

Key Features

• Premium aluminum oxide blend abrasive for faster cutting and longer disc life
• 4.5-inch diameter fits standard angle grinders
• 50-grit coarse rating suited for stock removal, weld grinding, and blending
• Pack of 4 discs for extended job-site availability
• Designed for use on ferrous metals including structural steel, pipe, and sheet metal

Compatibility

Designed as a replacement-style fiber disc for use on 4.5-inch angle grinders requiring a fiber-backed abrasive disc with a compatible backup pad.

Installation Notes

Installation and use should be performed by a qualified tradesperson familiar with angle grinder operation and abrasive disc safety. Always power down and disconnect the grinder before mounting or removing a disc. A rigid or semi-rigid backup pad matched to the disc diameter is required to prevent disc deflection and ensure even abrasive contact. Inspect each disc for cracks or damage before mounting, and never exceed the maximum RPM rating marked on the disc or grinder.
