Merit Abrasives 08834122035 Flap Wheel 80 Grit 4x1 in

Product Description

The MERIT ABRASIVES 08834122035 is a coated, unmounted aluminum oxide flap wheel designed for aggressive material removal and surface conditioning on metal and similar substrates. Built at 80 grit, it falls in the medium grade range, making it effective for blending welds, deburring edges, and general stock removal without excessive surface damage. The cloth backing provides flexibility and durability through the flap assembly. At a maximum rated speed of 12,000 RPM, this wheel is compatible with a wide range of rotary tools and bench-mounted arbors. Licensed metalworkers, fabricators, and maintenance technicians will find this wheel well-suited to both production and field applications.

This flap wheel is intended for use in metal fabrication shops, maintenance facilities, and manufacturing environments where consistent abrasive performance is required. It is sold individually and fits rotary tools, mandrel setups, or bench arbors equipped with a 5/8-inch center hole interface. Typical applications include weld blending, surface prep for coating, deburring of ferrous and non-ferrous metals, and light contouring work. Its 4-inch outside diameter provides good surface contact on flat and mildly curved workpieces.

Installation Notes

This wheel is installed by a fabricator or machinist onto a compatible arbor or mandrel before mounting in the rotary tool or machine spindle.
