3M 7100021244 Multi-finishing Wheel 8x24x3 in Medium

Product Description

The 3M 7100021244 is a convolute multi-finishing wheel designed for final surface finishing operations in industrial and trade applications. Built with an open web construction, it allows swarf and debris to escape during use, reducing loading and extending wheel life. The wheel measures 8 inches in diameter, 24 inches in width, and 3 inches in arbor hole size, and is convolutely wound on a core for consistent density throughout. The abrasive mineral is medium grade silicon carbide, suited for controlled material removal and surface refinement on metal, composite, and similar substrates. At 24 pounds, this is a production-scale wheel intended for stationary finishing equipment.

This wheel is used in metal fabrication shops, maintenance facilities, and production environments where consistent final finishing results are required. The soft, conformable, and flexible 2S density rating allows the wheel to follow surface contours, making it appropriate for blending, deburring, and pre-polish finishing stages. It is typically installed on wide-belt or drum finishing machines by machinists, fabricators, or maintenance technicians working with stationary abrasive equipment.

Key Features

• Open web construction reduces loading and extends service life during final finishing passes
• Convolutely wound on a core for uniform density and consistent finish quality
• Soft, conformable, flexible 2S density conforms to irregular and contoured surfaces
• Medium grade silicon carbide abrasive mineral for controlled stock removal and surface refinement
• Production-scale dimensions: 8 inches x 24 inches x 3 inches for high-throughput equipment

Compatibility

Designed for use on stationary convolute finishing equipment that accepts an 8-inch diameter, 24-inch wide wheel with a 3-inch arbor bore. Verify machine arbor size, speed rating, and maximum wheel weight capacity before installation.

Installation Notes

Installation should be performed by a qualified machinist or equipment technician. Power down and lock out the finishing machine before mounting or removing the wheel in accordance with OSHA lockout/tagout procedures. Confirm the machine spindle speed does not exceed the maximum RPM rating marked on the wheel or packaging. Inspect the wheel for damage before mounting and do not use a wheel that shows cracking, delamination, or other visible defects.
