Value Collection FA7780 Type 27 Grinding Wheel 7 in 80 Grit

Product Description

The VALUE COLLECTION FA7780 is a Type 27 depressed center grinding wheel designed for aggressive material removal on metal surfaces. Built with aluminum oxide abrasive and a resinoid bond, this medium-grade wheel delivers consistent stock removal across steel, iron, and similar ferrous materials. At 7 inches in diameter with a 1/8-inch thickness and 7/8-inch arbor hole, it mounts to standard angle grinders and is rated to 8,500 RPM maximum. The aluminum oxide grain holds up well under sustained grinding pressure, making it a reliable choice for fabricators, pipefitters, welders, and maintenance technicians working in industrial and construction environments.

This wheel is suited for surface grinding, weld blending, and deburring applications in both shop and field settings. The Type 27 depressed center profile positions the abrasive face slightly below the backing plate, allowing flush grinding along flat surfaces and into corners. It fits angle grinders with a 7/8-inch arbor and is commonly used in metal fabrication shops, structural steel work, pipe work, and general maintenance grinding tasks requiring a medium 80-grit cut rate.

Key Features

• Type 27 depressed center profile for flush surface grinding and weld blending
• Aluminum oxide abrasive with medium 80-grit rating for balanced cut rate and finish
• Resinoid bond construction for durability under sustained grinding loads
• 8,500 RPM maximum speed rating for use with standard 7-inch angle grinders
• 7/8-inch arbor hole fits common angle grinder spindles
• 1/8-inch wheel thickness suited for general-purpose stock removal

Compatibility

Designed for use with 7-inch angle grinders equipped with a 7/8-inch arbor spindle. Suitable for grinding ferrous metals including steel and iron in fabrication and maintenance applications.

Installation Notes

Installation and wheel changes should be performed by qualified personnel following ANSI B7.1 safety standards for abrasive wheels. Always inspect the wheel for cracks or damage before mounting and ensure the grinder is fully powered down and unplugged before changing wheels. Confirm the grinder spindle speed does not exceed the 8,500 RPM maximum rating stamped on the wheel. Use the correct flange hardware and tighten the arbor nut securely before operation.
