Value Collection FA4580 Type 27 Grinding Wheel 4-1/2 in 80 Grit

Product Description

The VALUE COLLECTION FA4580 is a Type 27 depressed center grinding wheel designed for aggressive material removal on metal surfaces. The wheel measures 4-1/2 inches in diameter and 1/8 inch thick, with a 7/8-inch arbor hole for standard angle grinder compatibility. It is constructed from aluminum oxide abrasive bonded with a resinoid bond, rated at 80 grit for medium-grade stock removal. Maximum rated speed is 13,300 RPM. This wheel is used by fabricators, welders, pipefitters, and general trade contractors for grinding welds, deburring steel, and surface preparation work.

The FA4580 fits standard 4-1/2-inch angle grinders commonly used in fabrication shops, job-site metalwork, and maintenance applications. The Type 27 depressed-center profile keeps the wheel hub recessed, allowing flat grinding passes close to workpiece surfaces without obstruction. The 80-grit aluminum oxide construction makes it well suited for carbon steel, stainless steel, and cast iron grinding where moderate material removal and surface blending are required.

Installation Notes

Installation should follow ANSI B7.1 safe-use guidelines for abrasive wheels. Inspect the wheel for cracks or chips before mounting and never use a damaged wheel. Ensure the grinder is unplugged or battery removed before changing wheels. Always use the proper guard and wear appropriate eye and face protection during operation.
