3M 7100177097 Flexible Flap Wheel 3.5 Inch Aluminum Oxide

Product Description

The 3M 7100177097 is an aluminum oxide flexible flap wheel designed for deburring, finishing, and surface prep on inside diameters and contoured workpieces. The flexible coated abrasive flaps conform to the surface and produce a consistent linear scratch pattern, making this wheel a practical choice for removing burrs, flash, and parting lines. The steel mandrel construction reduces chatter during operation, supporting steadier contact and more controlled results. At 3.5 inches in diameter, this wheel suits a range of portable and bench-mounted rotary tools used in fabrication and metalworking environments.

This flap wheel is intended for use on ferrous and non-ferrous metals where clean inside-diameter finishing or contour blending is required. It is well suited to tasks such as edge deburring, parting line removal, and smoothing irregular interior surfaces. The design keeps dust directed away from the workpiece, helping maintain visibility of the work area during use. Fabricators, machinists, and metalworking professionals are the primary users of this wheel in both production and maintenance settings.

Key Features

• Flexible flaps conform to flat and contoured surfaces for consistent coverage
• Produces a linear scratch pattern suited to inside-diameter finishing
• Aluminum oxide abrasive cuts efficiently on ferrous and non-ferrous materials
• Steel mandrel reduces chatter for steadier operation
• Designed to direct dust away from the workpiece during use
• Effective for deburring edges, removing flash, and smoothing parting lines

Compatibility

Designed as a replacement-style flexible flap wheel for rotary tools and die grinders requiring a 3.5-inch diameter abrasive wheel with mandrel attachment.

Installation Notes

Installation and use should be performed by qualified metalworking or fabrication personnel familiar with rotary abrasive tooling. Ensure the tool is powered off and unplugged before mounting or removing the wheel. Verify that the tool RPM rating meets or exceeds the wheel RPM rating before operation. Follow applicable ANSI and OSHA safety standards for abrasive wheel use, including proper eye and face protection.
