3M 7010309665 Deburring Wheel 4 Inch Aluminum Oxide

Product Description

The 3M 7010309665 is a unitized deburring wheel designed for aggressive material removal and edge finishing on metal workpieces. Built with aluminum oxide abrasive at a density grade of 8 (hard), it delivers consistent cutting action while maintaining wheel integrity under continuous use. The 4-inch diameter and 1/4-inch face width make it well-suited for precision deburring, light grinding, and surface blending tasks. Rated to 12,100 RPM, it is compatible with high-speed rotary tooling found in production and fabrication environments. Installation and operation require compliance with all applicable ANSI abrasive wheel safety standards.

This deburring wheel is intended for use in metalworking and fabrication settings where burr removal, edge breaking, and surface conditioning are required. Its coarse grade and hard density make it appropriate for ferrous and non-ferrous metals in both job shop and production line applications. Compatible tooling includes centerless grinders, die grinders, inline sanders, manual backstands, and pressure assist backstands. The 1/4-inch center hole and compact face width allow it to reach into tight areas that larger wheels cannot access.

Key Features

• Aluminum oxide abrasive construction for consistent, repeatable cutting on metal
• Density grade 8 hard unitized wheel maintains shape and resists loading under pressure
• Coarse grade for aggressive deburring and edge conditioning
• Maximum operating speed of 12,100 RPM for compatibility with common rotary tools
• 4-inch diameter with 1/4-inch face width and 1/4-inch center hole for precise fitment
• Compatible with multiple tool types including die grinders and centerless grinders

Compatibility

Compatible with centerless grinders, die grinders, inline sanders, manual backstands, and pressure assist backstands. Designed as an OEM-style replacement or direct-fit deburring wheel for applications requiring a 4-inch unitized aluminum oxide wheel with a 1/4-inch arbor hole.

Installation Notes

Mounting and operation should be performed by qualified personnel following all applicable ANSI B7.1 abrasive wheel safety standards. Always de-energize and lock out the tool before mounting or removing the wheel. Verify that the tool spindle speed does not exceed the 12,100 RPM maximum rated speed of this wheel before operation. Inspect the wheel for damage prior to each use and never use a wheel that shows cracks, chips, or other visible defects.
