3M 7000046074 Deburring Wheel 12x2x5 in 9S Fine Silicon Carbide

Product Description

The 3M 7000046074 is a convolute deburring and finishing wheel designed for demanding metalworking applications. Constructed with a hard, durable density-9 structure and a fine-grade silicon carbide abrasive mineral, this wheel delivers consistent stock removal and surface finishing in one pass. It measures 12 inches in diameter by 2 inches wide with a 5-inch arbor hole and weighs 5.1 pounds. The convolute winding method layers abrasive material around a rigid core, producing a firm wheel that resists loading and maintains its shape through extended use. Metalworking shops, fabricators, and maintenance machinists reach for this wheel when edge deburring, blending weld seams, or cleaning up machined surfaces on ferrous and non-ferrous workpieces.

This wheel is suited for use on bench grinders, pedestal grinders, and automated deburring machines that accept a 5-inch arbor. It is appropriate for light to medium industrial finishing work including deburring drilled or punched holes, removing sharp edges from cut stock, and surface conditioning prior to coating or assembly. The fine-grade silicon carbide abrasive makes it a strong choice for non-ferrous metals such as aluminum, brass, and copper, as well as harder ferrous alloys where a controlled, refined finish is required. It is sold as a single wheel unit.

Key Features

• Fine-grade silicon carbide abrasive mineral for controlled material removal and surface conditioning
• Hard density-9 rating provides a firm, durable wheel structure that holds its form under load
• Convolute construction wound on a rigid core for consistent performance throughout wheel life
• 12-inch diameter with 2-inch face width suits standard bench and pedestal grinder setups
• 5-inch arbor hole accommodates common industrial grinder spindles

Compatibility

Designed for use on bench grinders, pedestal grinders, and automated deburring equipment configured with a 5-inch arbor. Suitable for deburring and finishing operations on ferrous and non-ferrous metals.

Installation Notes

Installation should be performed by a qualified operator familiar with abrasive wheel safety practices. Always power down and lock out the machine before mounting or removing the wheel. Verify that the grinder's rated speed meets or exceeds the wheel's maximum operating speed before use, and inspect the wheel for cracks or damage prior to each mounting. Follow ANSI B11 and applicable OSHA standards for abrasive wheel guarding and personal protective equipment.
