3M 7100056129 Deburring Wheel 14x3x8 in 7S Fine

Product Description

The 3M 7100056129 is a convolute deburring and finishing wheel designed for use in metalworking and fabrication environments. Wound convolutely on a rigid core, the wheel delivers consistent stock removal and surface finishing across its full face width. It uses a fine-grade silicon carbide abrasive mineral, rated at a 7S density for hard, long-lasting performance. At 14 inches in diameter, 3 inches wide, and sized for an 8-inch arbor bore, it fits standard industrial bench or pedestal grinders. Machinists, fabricators, and maintenance technicians use this wheel for deburring edges, blending surfaces, and light finishing on metal workpieces.

This wheel is suited for deburring and finishing operations on ferrous and non-ferrous metals in industrial, manufacturing, and maintenance-repair-operations settings. The fine silicon carbide abrasive makes it appropriate for final-stage deburring where surface finish quality matters. It is typically mounted on a stationary bench grinder or pedestal machine and used by metal fabricators or toolroom machinists performing edge cleanup and surface blending tasks after machining or stamping operations.

Key Features

• Fine-grade silicon carbide abrasive mineral for controlled material removal and smooth finish
• Convolutely wound construction provides consistent density and even wear across the wheel face
• 7S density rating delivers hard, long-lasting performance under continuous use
• 14-inch diameter with 3-inch face width and 8-inch arbor bore for standard industrial machine compatibility
• Sold individually (each) for straightforward replacement stocking

Compatibility

Designed as an OEM-style replacement or direct-fit deburring wheel for standard industrial bench grinders and pedestal machines accepting an 8-inch arbor bore.

Installation Notes

Installation should be performed by a qualified machinist or maintenance technician following the machine manufacturer's mounting instructions. Always power down and lock out the grinder before mounting or removing the wheel. Inspect the wheel for cracks or damage before installation and verify that the machine's rated operating speed meets or exceeds the wheel's maximum RPM rating. Follow applicable ANSI B7.1 safety standards for abrasive wheel mounting and guarding.
