Merit Abrasives 08834137503 Mounted Flap Wheel 180 Grit

Product Description

The MERIT ABRASIVES 08834137503 is a mounted flap wheel designed for precision surface finishing, deburring, and blending in tight or contoured areas. Constructed with aluminum oxide abrasive on a cloth backing, it delivers consistent cut and finish across ferrous and non-ferrous metals. At 180 grit (Very Fine grade), this wheel removes minor tool marks and produces a smooth, refined surface. It mounts via a 1/8-inch shank for use in electric or pneumatic die grinders and rotary tools, and carries a maximum rated speed of 30,000 RPM. Machinists, fabricators, and metal finishing technicians reach for this style of wheel when working in bores, slots, and recessed profiles where flat abrasives cannot reach.

This mounted flap wheel suits light deburring, surface blending, and finish work on intricate or hard-to-reach workpiece geometry. It is well suited for use in tool-and-die shops, precision machining operations, and general metal fabrication environments. The 1-3/16-inch diameter and 3/16-inch face width make it appropriate for smaller bores, inside radii, and detailed contour work. Typical applications include finishing weld areas, cleaning casting flash, and smoothing machined surfaces prior to inspection or assembly.

Key Features

• 180 grit aluminum oxide abrasive — Very Fine grade for smooth surface finishing and light deburring
• Cloth backing provides flexibility and conformability on curved or contoured surfaces
• 1/8-inch shank diameter compatible with standard die grinders and rotary tool collets
• 30,000 RPM maximum rated speed suitable for high-speed pneumatic and electric rotary tools
• Compact 1-3/16-inch diameter and 3/16-inch face width designed for tight or recessed workpiece geometry
• No interleaf construction for direct abrasive contact and consistent material removal

Compatibility

Designed for use in standard 1/8-inch collet die grinders and rotary tools rated for coated abrasive mounted wheels up to 30,000 RPM.

Installation Notes

Installation is performed by machinists or metal finishing technicians using a compatible rotary tool or die grinder with a 1/8-inch collet. Always confirm the tool's rated RPM meets or exceeds the wheel's 30,000 RPM maximum before mounting. Inspect the wheel for damage before each use and ensure the collet is properly tightened before operation. Wear appropriate eye protection and follow all applicable ANSI abrasive safety standards during use.
