3M 7000045878 Convolute Deburring Wheel 14 Inch

Product Description

The 3M 7000045878 is a convolute-constructed, non-woven abrasive wheel designed for light deburring, polishing, and blending on metal, composite, and glass surfaces. The soft construction allows the wheel to conform to workpiece contours, keeping fresh abrasive mineral continuously exposed throughout the cut. At 14 inches in diameter and 2.7 inches wide, it fits bench grinders and pedestal-style finishing machines used in fabrication and metalworking shops. The non-woven web runs cool, reducing heat buildup on heat-sensitive materials and minimizing smearing that extends prep time between operations.

This wheel is suited for light-duty production finishing and repair work where removing fine burrs without aggressive stock removal is the goal. Typical applications include deburring machined parts, blending weld seams, and surface conditioning on ferrous and non-ferrous metals as well as composites and glass. The convolute build provides consistent, repeatable results across high-volume runs. Metal fabricators, tool-and-die shops, and general manufacturing maintenance crews are the primary users of this wheel type.

Key Features

• Convolute construction continuously exposes fresh abrasive mineral for consistent cut and finish
• Soft, conformable build reduces operator effort compared to harder wheel grades
• Non-woven web runs cool and minimizes heat impact on sensitive materials
• Unique resin system reduces smearing, cutting clean-up and prep time between passes
• Multi-purpose capability: deburrs, polishes, blends, cleans, and finishes in a single wheel
• Economical system for fine burr removal with a polished surface result

Compatibility

Designed as an OEM-style replacement or direct-fit wheel for bench grinder and pedestal finishing machine spindles that accept 14-inch diameter convolute abrasive wheels.

Installation Notes

Installation should be performed by qualified personnel familiar with abrasive wheel mounting procedures. Power down and lockout/tagout the machine before mounting or removing any wheel. Inspect the wheel for cracks or damage before installation and verify the machine's rated speed does not exceed the wheel's maximum RPM rating. Follow ANSI B7.1 standards for safe use, handling, and protection of abrasive wheels.
