3M 7000045862 Deburring Wheel 8 Inch Silicon Carbide

Product Description

The 3M 7000045862 is a convolute deburring wheel designed for edge blending, deburring, and surface conditioning of metal workpieces. Built with silicon carbide abrasive at a hard density grade (Density 8), this wheel delivers consistent, controlled material removal across a range of ferrous and non-ferrous metals. It mounts on backstands, bench grinders, benchtops, and inland sanders, making it a practical choice for fabrication shops and production grinding environments. The wheel measures 8 inches in diameter with a 1 inch face width and a 3 inch center hole, and it is rated to a maximum of 4,500 RPM. Installation and setup require a compatible mandrel or adapter, specifically the 356 adapter.

This deburring wheel is suited for metalworking applications where consistent deburring and edge finishing are required on production or maintenance lines. The convolute construction bonds abrasive grain uniformly throughout the wheel body, providing a predictable cut as the wheel wears. It is compatible with standard backstands, bench grinders, benchtops, and inland sanders, making it adaptable to common shop configurations. Typical users include machinists, fabricators, and tool-and-die technicians performing post-machining cleanup or weld seam conditioning.

Installation Notes

Installation should be performed by a qualified machinist or shop technician familiar with abrasive wheel mounting procedures. Always power down and lock out the grinder or backstand before mounting or removing the wheel. Verify that the spindle speed of the host machine does not exceed the 4,500 RPM rating marked on the wheel. Confirm mandrel and adapter compatibility before use and inspect the wheel for damage prior to each mounting.
