Norton 088341-37474 Micro-mini Grind-o-flex 240 Grit Flap Wheel

Product Description

The NORTON 088341-37474 is a Merit Micro-Mini Grind-O-Flex abrasive flap wheel designed for precision surface finishing and blending in tight spaces and hard-to-reach areas. At 3/8 inch diameter by 3/8 inch face width with a 1/8 inch arbor hole, this compact wheel mounts to die grinders and rotary tools for controlled material removal on metal, welds, and contoured surfaces. The 240 grit designation places it in the fine finishing range, making it suited for final-pass blending, light deburring, and surface preparation before coating or inspection. Each box contains 10 wheels.

This flap wheel is used in fabrication shops, maintenance and repair operations, and field service work where access is limited and a full-size grinding wheel cannot reach. Common applications include internal bore finishing, tube and pipe blending, weld cleanup in recessed joints, and deburring of machined components. The micro-mini form factor is specifically engineered for use with pencil die grinders and small-shank rotary tools. It is installed and used by machinists, pipefitters, welders, and general metalworkers.

Installation Notes

This abrasive wheel is installed and used by machinists, welders, and maintenance technicians using pneumatic or electric die grinders. Always confirm the tool spindle speed rating meets or exceeds the maximum RPM rating of the wheel before operation. Inspect each wheel for damage before mounting, and ensure the arbor shank is fully seated and secured in the tool collet. Wear appropriate eye protection and follow applicable ANSI B11 and OSHA grinding safety standards during use.
