3M 7000000768 Cut and Polish Wheel 8x2.5x3 in 7A Med

Product Description

The 3M 7000000768 is a convolutely wound cut and polish wheel built for tough blending and finishing work on metal surfaces. Constructed with a hard density-7 core and medium-grade aluminum oxide abrasive mineral, this wheel delivers aggressive cutting action while leaving a consistent, uniform grain finish. At 8 inches in diameter, 2.5 inches in width, and 3 inches in bore size, it fits standard bench and pedestal grinder arbors used in fabrication and production environments. Weighing 28 pounds, it is a substantial wheel intended for sustained industrial use. Licensed trades and metal finishing professionals install and operate this wheel in shop settings.

This wheel is suited for applications requiring removal of surface defects, coarse grind lines, forging marks, and machining mismatches on metal workpieces. Its medium-grade aluminum oxide construction makes it effective across a range of ferrous and non-ferrous blending tasks in manufacturing, fabrication, and metal finishing shops. It is sold individually and is appropriate where a hard, long-lasting wheel with repeatable grain finish results is required.

Key Features

• Medium-grade aluminum oxide abrasive for aggressive yet controlled stock removal
• Hard density-7 construction for long wheel life in demanding production use
• Convolutely wound on a core for consistent performance throughout wheel life

• 8 inches x 2.5 inches x 3 inches sizing fits standard industrial grinder arbors

Compatibility

Designed as an OEM-style replacement or direct-use wheel for standard industrial bench and pedestal grinders with a 3-inch arbor bore in metal fabrication and finishing applications.

Installation Notes

Installation and mounting of abrasive wheels should be performed by qualified personnel following ANSI B7.1 safe use standards. Always power down and lock out the grinder before mounting or removing the wheel. Inspect the wheel for cracks or damage before each use and perform a ring test per manufacturer guidelines. Use proper flanges and ensure the wheel speed rating meets or exceeds the grinder RPM rating before operation.
