Merit Abrasives 66254419713 Deburring Wheel 8 in Silicon Carbide

Product Description

The MERIT ABRASIVES 66254419713 is a convolute deburring wheel designed for edge finishing, burr removal, and surface blending on metal workpieces. Built around a silicon carbide abrasive with a fine grade and a density rating of 9 (hard), this wheel delivers consistent, controlled material removal without aggressive stock loss. The 8-inch diameter and 0.5-inch face width make it well-suited for bench and pedestal grinder applications where precision and repeatability matter. It is installed and operated by machinists, tool-and-die workers, fabricators, and maintenance technicians who require reliable deburring on production or shop-floor equipment.

This wheel is intended for use on bench grinders and pedestal grinders in industrial, manufacturing, and maintenance shop environments. The convolute construction — layers of abrasive-coated material wound tightly around a core — provides a firm, consistent cutting surface across the full face width. It is appropriate for deburring ferrous and non-ferrous metals as well as light surface conditioning tasks. The 3-inch center hole fits standard arbor sizes common to full-size bench and pedestal grinder configurations.

Key Features

• Silicon carbide abrasive for effective deburring on metals and non-ferrous materials
• Fine grade with density 9 hard rating for firm, controlled material removal
• Convolute wheel construction provides consistent face contact throughout wheel life
• Rated to 4,500 RPM maximum — do not exceed this speed in operation
• 8-inch diameter with 0.5-inch face width and 3-inch center hole for standard arbor fitment
• Compatible with bench grinders and pedestal grinders

Compatibility

Designed for use on bench grinders and pedestal grinders with a 3-inch arbor hole fitment. Confirm grinder spindle speed does not exceed 4,500 RPM before mounting.

Installation Notes

Installation should be performed by a qualified machinist or maintenance technician familiar with abrasive wheel safety. Power down and lockout-tagout the grinder before mounting or removing the wheel. Verify that the machine's rated spindle speed does not exceed the wheel's 4,500 RPM maximum rating prior to operation. Inspect the wheel for cracks or damage before each use and follow ANSI B7.1 safety requirements for the mounting and use of abrasive wheels.
