3M 7100310727 Fiber Disc 4-1/2 in 36 Grit Ceramic Quick-change

Product Description

The 3M 7100310727 is a precision shaped ceramic abrasive fiber disc designed for aggressive material removal on metal and other hard surfaces. Built around a premium ceramic alumina grain bonded with a resinoid bond to a fiber backing, this disc delivers consistent cut rates and extended service life compared to conventional aluminum oxide discs. At 36 grit, it falls in the extra coarse grade range, making it well-suited for heavy stock removal, weld blending, and surface prep work. The TN quick-change attachment allows fast disc swaps without wrenches, reducing downtime during production or field grinding operations. Rated to a maximum of 13,300 RPM, the disc is engineered for use with compatible right-angle grinders and disc sanders.

This disc is used in fabrication shops, metal service centers, and field maintenance environments where high-volume grinding on steel, stainless steel, and other hard metals is required. The 4.5-inch diameter fits a standard disc tool footprint common across industrial and trade applications. The extra coarse 36 grit makes it the right choice for initial weld seam removal, heavy scale grinding, and aggressive surface conditioning before moving to finer abrasives. Licensed tradespeople in pipefitting, ironwork, and structural fabrication will find this disc appropriate for daily production grinding tasks.

Compatibility

Designed for use with right-angle grinders and disc sanders that accept TN quick-change style fiber disc attachments with a 4.5-inch disc capacity.

Installation Notes

Installation and disc changes should be performed by qualified personnel familiar with angle grinder safety procedures. Always power down and disconnect the grinder from its power source before mounting or removing a disc. Verify the grinder RPM rating meets or exceeds the disc maximum rated speed of 13,300 RPM before operation. Inspect the disc for damage prior to each use and follow applicable ANSI B7.1 grinding wheel safety standards.
