Norton 66261055258 Silicon Carbide Deburring Wheel 8 Inch

Product Description

The NORTON 66261055258 is a convolute deburring wheel designed for edge blending, deburring, and light surface conditioning on metal workpieces. It measures 8 inches in diameter with a 2-inch face width and a 3-inch center hole. The abrasive matrix is silicon carbide at a fine grade with a density rating of 8 and a hard density grade, making it well suited for consistent, controlled material removal on ferrous and non-ferrous metals. Rated to a maximum of 3,650 RPM, this wheel mounts directly on bench or pedestal grinder spindles and is used by machinists, pipefitters, fabricators, and toolroom technicians.

This convolute wheel is appropriate for production and maintenance deburring on parts with tight edge-finish requirements. The silicon carbide abrasive cuts efficiently on aluminum, brass, copper, and other non-ferrous materials, as well as cast iron. It fits standard bench and pedestal grinder arbors sized for a 3-inch center hole. The hard density grade maintains wheel geometry under steady contact pressure, reducing the frequency of wheel dressing and redressing during a production run.

Key Features

• Silicon carbide abrasive in a fine grade for smooth deburring and edge blending
• Convolute construction maintains consistent abrasive contact throughout wheel life
• Hard density grade (Density 8) resists deformation under sustained grinding pressure
• 3,650 RPM maximum speed rating for use on bench and pedestal grinders
• 3-inch center hole fits standard bench and pedestal grinder spindle arbors
• 8-inch diameter with 2-inch face width provides broad contact area for efficient deburring

Compatibility

Designed for use with bench grinders and pedestal grinders. The 3-inch center hole and 8-inch diameter are the primary fitment constraints when selecting this wheel for a specific machine.

Installation Notes

Installation should be performed by a qualified technician familiar with abrasive wheel mounting procedures. Always power down and lockout the grinder before mounting or removing the wheel. Verify that the machine spindle speed does not exceed the 3,650 RPM maximum rating marked on the wheel. After mounting, allow the wheel to run at operating speed for at least one minute with personnel clear of the wheel plane before beginning work, in accordance with ANSI B11 and OSHA abrasive wheel standards.
