Tru-maxx Fdt A016-125 Fiber Disc 5 in 16 Grit Aluminum Oxide

Product Description

The TRU-MAXX FDT A016-125 is a 5-inch aluminum oxide fiber disc designed for aggressive material removal on metal, weld seams, and rough surface preparation. Running on a resinoid bond with a fiber backing, this disc mounts via a 7/8-inch arbor hole and is rated to 12,250 RPM. At 16 grit, it falls into the very coarse grade category, making it suited for fast stock removal rather than finishing passes. It is sold individually but requires a minimum order of 25 units. Angle grinder operators and fabricators working in metal shops, shipyards, and structural steel applications are the primary users of this disc type.

This disc is intended for use on angle grinders and disc grinders equipped with a 5-inch backup pad and a 7/8-inch arbor. Very coarse 16-grit aluminum oxide cuts aggressively into mild steel, cast iron, and welds. It is a standard choice for weld blending, surface conditioning, deburring heavy stock, and removing rust or scale from structural components. The maroon-colored fiber backing provides rigidity and heat resistance during high-pressure grinding applications common in fabrication and maintenance settings.

Key Features

• 16 grit aluminum oxide abrasive for maximum stock removal rate
• Fiber backing with resinoid bond handles high grinding pressure without premature breakdown
• Rated to 12,250 RPM for use with standard 5-inch angle grinders
• 7/8-inch arbor hole fits most common backup pad configurations
• Very coarse grade suitable for weld blending, scale removal, and heavy deburring
• Maroon disc color for quick grade identification in the shop

Compatibility

Designed for use with 5-inch angle grinders and disc grinders fitted with a 7/8-inch arbor backup pad. Confirm your grinder does not exceed 12,250 RPM before mounting this disc.

Installation Notes

This disc is installed by a grinder operator or metal fabricator following standard abrasive safety practices. Always power down and disconnect the grinder before mounting or removing a disc. Inspect the disc for cracks or damage before each use and never operate above the rated maximum RPM. ANSI B7.1 and applicable OSHA abrasive wheel standards apply to disc installation and guarding requirements.
