3M 7000120808 Scotch-brite Mu-wl 8 Inch Finishing Wheel

Product Description

The 3M 7000120808 is a Scotch-Brite MU-WL Multi-Finishing Wheel built with convolute construction for final finishing and surface cleaning on metal workpieces. The wheel uses silicon carbide mineral in a combination of grades bonded into a soft-density, non-woven web that runs cool and conforms readily to curved, contoured, and flat surfaces. At 8 inches in diameter and 4.2 inches wide, it mounts on standard arbor-driven bench or pedestal grinders and is well suited for controlled, consistent finishing passes where minimizing heat buildup is a priority.

This wheel is intended for final finishing applications on stainless steel, aluminum, brass, copper, ferrous metals, and other non-ferrous metals. The lighter density and moderate aggressiveness make it a practical choice for shops and field technicians who need repeatable surface finish results across production runs or individual fabrication work. Typical applications include deburring, blending, and surface preparation before coating or passivation on both flat and profiled metal stock.

Key Features

• Convolute construction delivers a balanced, smooth-running wheel throughout its service life
• Open, non-woven web runs cool and reduces heat transfer to heat-sensitive base materials
• Highly conformable construction maintains consistent contact on contoured and curved surfaces
• Moderate aggressiveness and lighter density provide controlled wear for consistent results over the life of the wheel
• Uniform silicon carbide grain suitable for final finishing on stainless steel, ferrous, and non-ferrous metals

Compatibility

Designed for use on stainless steel, aluminum, brass, copper, and other ferrous and non-ferrous metals. Mounts on arbor-driven bench grinders and pedestal grinders that accept convolute finishing wheels.

Installation Notes

Installation should be performed by a qualified metalworker or fabricator following the grinder manufacturer's arbor and speed specifications. Power down and lock out the grinder before mounting or removing the wheel. Verify that the machine's maximum RPM rating meets or exceeds the wheel's rated speed before operating. Inspect the wheel for damage before each use and do not operate a cracked or delaminated wheel.
