Merit Abrasives 08834122055 Flap Wheel 60 Grit 4x2 in

Product Description

The MERIT ABRASIVES 08834122055 is an unmounted aluminum oxide flap wheel designed for surface finishing, blending, and deburring on metal and other hard materials. The wheel measures 4 inches in diameter by 2 inches wide and runs at a maximum of 12,000 RPM, making it suitable for high-speed angle grinders and bench-mounted spindles. At 60 grit, it falls in the medium grade range, removing material efficiently while leaving a consistent surface finish. The 5/8-inch center hole fits standard arbor configurations. Weighing 0.8 pounds, this coated abrasive wheel is built for production and maintenance grinding tasks handled by machinists, fabricators, and maintenance technicians.

This flap wheel is used in metalworking shops, fabrication facilities, and industrial maintenance environments. It is well suited for blending weld seams, cleaning oxidation, and smoothing rough edges on steel, aluminum, and similar materials. The unmounted design requires pairing with an appropriate spindle or mandrel rated for the wheel dimensions and speed. No interleaf material is included between the abrasive flaps, which delivers more aggressive cutting action and direct flap-to-workpiece contact.

Compatibility

Designed for use with spindles and mandrels accepting a 5/8-inch arbor hole and rated for wheels up to 4 inches in diameter at 12,000 RPM or higher.

Installation Notes

Installation and use should be performed by qualified machinists or grinding technicians familiar with abrasive wheel safety standards, including ANSI B7.1 guidelines. Always power down and de-energize the grinder or spindle before mounting or removing the wheel. Verify that the spindle speed does not exceed the 12,000 RPM maximum rating marked on the wheel. Eye protection and appropriate PPE are required during grinding operations.
