3M 7000077967 Mounted Flap Wheel Silicon Carbide Fine

Product Description

The 3M 7000077967 is a mounted flap wheel designed for surface finishing, blending, and light deburring on metal and other hard materials. It uses a non-woven silicon carbide abrasive construction in a fine grade, making it well suited for controlled material removal and surface conditioning where a consistent finish is required. The wheel mounts via a 1/4-inch shank and is rated to a maximum of 8,500 RPM. Machinists, fabricators, and tool and die professionals use this style of wheel with die grinders and bench-mounted spindles for detail work on contoured or flat surfaces.

This mounted flap wheel is used in metalworking and light fabrication environments, including job shops, maintenance facilities, and production lines. It is suited for finishing operations on steel, stainless steel, aluminum, and similar materials. The 3-inch diameter and 1-3/4-inch face width provide a useful contact area for surface blending on both flat and curved workpiece geometry. It is typically used wherever a consistent, fine surface finish is needed without aggressive stock removal.

Key Features

• Non-woven silicon carbide abrasive for consistent fine-grade surface finishing
• 3-inch outer diameter with a 1-3/4-inch face width for broad contact area
• 1/4-inch shank mount for compatibility with standard die grinders and rotary tools
• 8,500 maximum RPM rating for safe use at typical die grinder operating speeds
• No interleaf construction for uniform abrasive contact across the face width

Compatibility

Designed for use with die grinders and rotary power tools that accept a 1/4-inch shank-mounted accessory. Verify that the tool's operating speed does not exceed the 8,500 RPM maximum rating of this wheel before use.

Installation Notes

Installation is performed by a machinist or fabricator using a die grinder or compatible rotary tool with a 1/4-inch collet. Ensure the tool is powered off and disconnected from its power source before mounting or removing the wheel. Confirm the tool's no-load RPM does not exceed the 8,500 RPM maximum stamped on the wheel. Wear appropriate eye protection and follow applicable ANSI B11 or OSHA grinding safety guidelines during operation.
