3M 7000046143 Deburring Wheel 6x3x1 in 8A Medium Grade

Product Description

The 3M 7000046143 is a convolutely wound deburring and finishing wheel designed for demanding metalworking applications. Built with a hard density 8A construction and medium-grade aluminum oxide abrasive mineral, this wheel delivers consistent cutting action and long service life. At 6 inches in diameter, 3 inches in width, and 1 inch bore, it fits standard bench grinder and arbor setups used by fabricators, machinists, and maintenance technicians. The convolutely wound design maintains a uniform abrasive surface as the wheel wears, reducing the need for frequent wheel changes during production runs.

This deburring wheel is suited for edge deburring, surface blending, and light finishing on metal workpieces in both shop and industrial maintenance environments. It performs on steel, aluminum, and similar metals where controlled material removal and surface conditioning are required. The medium aluminum oxide grade balances cut rate with surface finish quality, making it a practical choice for general deburring tasks where fine surface prep follows downstream.

Key Features

• Convolutely wound construction maintains consistent abrasive contact throughout wheel life
• Hard 8A density provides long-lasting performance in high-use deburring applications
• Medium-grade aluminum oxide mineral for balanced cut rate and surface finish
• 6 inches x 3 inches x 1 inch dimensions fit standard bench grinder arbors
• Sold individually (each unit)

Compatibility

Designed as an OEM-style replacement or direct-fit deburring wheel for standard bench grinders and arbor-mount finishing equipment accepting a 6-inch diameter, 3-inch wide, 1-inch bore wheel.

Installation Notes

Installation should be performed by a qualified technician familiar with abrasive wheel safety practices. Always power down and lock out the grinder or arbor machine before mounting or removing the wheel. Verify that the machine spindle speed rating meets or exceeds the maximum RPM rating of the wheel before operation. Inspect the wheel for damage before each use and ensure flanges and mounting hardware are properly seated per the equipment manufacturer guidelines.
