Arc Abrasives 11390 Flap Wheel 3x1x1/4 in 60 Grit

Product Description

The ARC ABRASIVES 11390 is a 60-grit flap wheel designed for light finishing and deburring on metal and similar workpiece surfaces. Measuring 3 inches in diameter by 1 inch wide with a 1/4-inch arbor, it mounts on a die grinder or handheld rotary tool for controlled material removal. The cotton cloth construction allows the wheel to flex and conform to curved or irregular surfaces. As each flap wears down, fresh abrasive grain is continuously exposed, maintaining a consistent cut rate throughout the wheel's service life.

This flap wheel is suited for fabrication, metalworking, and pipe fitting applications where access to tight or awkward areas is required. It performs well on inside angles, internal pipe surfaces, weld cleanup, and light edge deburring. Typical users include pipefitters, welders, and maintenance technicians working on steel, stainless, and aluminum components in both shop and field environments.

Key Features

• 60-grit abrasive for light finishing and controlled deburring
• Cotton cloth flap construction conforms to irregular and contoured surfaces
• Self-renewing flap design continuously exposes fresh abrasive grain as the wheel wears
• 1/4-inch arbor fits standard die grinders and rotary tools
• Compact 3 inches x 1 inch profile accesses tight angles and internal pipe surfaces

Compatibility

Designed as a standard 1/4-inch arbor flap wheel for use with die grinders and rotary tools that accept 1/4-inch shank accessories.

Installation Notes

Installation and operation should be performed by a qualified technician familiar with rotary abrasive tooling. Confirm the tool's rated RPM meets or exceeds the wheel's maximum operating speed before mounting. Secure the arbor firmly and ensure the wheel runs true before applying it to the workpiece. Always use appropriate personal protective equipment, including eye and face protection, when operating abrasive wheels.
