3M 7100033196 Mounted Flap Wheel 3in 1in 120 Grit Ceramic

Product Description

The 3M 7100033196 is a ceramic alumina coated mounted flap wheel designed for precision grinding, blending, and finishing on metal and other hard surfaces. The wheel measures 3 inches in diameter with a 1 inch face width and mounts via a 1/4 inch shank for use with standard die grinders and rotary tools. At 120 grit in a fine grade, it delivers a consistent scratch pattern suited to surface prep, weld blending, and deburring tasks. The X-weight cloth backing provides durability and flexibility under load, and the wheel is rated to a maximum of 20,000 RPM. Fabricators, pipe fitters, and metal finishing technicians are the primary users of this type of abrasive accessory.

This mounted flap wheel is well suited to tight-access grinding and blending in fabrication shops, mechanical contracting environments, and field repair work. The shank-mount configuration allows direct chuck-in to a 1/4 inch collet die grinder, making it practical for inside diameter work, weld seam blending in confined areas, and edge radiusing on structural components. The fine 120 grit designation makes it appropriate for finishing passes rather than aggressive stock removal.

Key Features

• 3 inch diameter with 1 inch face width for broad contact coverage
• 120 grit fine ceramic alumina abrasive for consistent surface finishing
• 1/4 inch shank mount compatible with standard die grinders and rotary tools
• X-weight cloth backing for durability and resistance to tearing under load
• 20,000 RPM maximum speed rating for use with high-speed rotary equipment
• No interleaf construction for direct flap-to-surface contact

Compatibility

Designed for use with die grinders and rotary tools equipped with a 1/4 inch collet or chuck. Verify that the tool's rated no-load RPM does not exceed the 20,000 RPM maximum speed of this wheel before use.

Installation Notes

Installation should be performed by a qualified technician familiar with abrasive wheel safety practices. Always confirm the tool's maximum RPM matches or is below the wheel's 20,000 RPM rating before mounting. Inspect the wheel for damage before each use and ensure the shank is fully seated and tightened in the collet. Wear appropriate personal protective equipment including eye protection and gloves when operating any mounted abrasive wheel.
