Norton 088341-37475 Microwheel Flap Wheel 320 Grit

Product Description

The NORTON 088341-37475 is a Merit Microwheel flap wheel designed for precision surface finishing in tight or hard-to-reach areas. The 3/8 inch diameter by 3/8 inch width profile combined with a 1/8 inch shank allows it to mount directly into a rotary tool, die grinder, or flex-shaft handpiece. At 320 grit, this wheel delivers fine finishing and light deburring passes on metal, composite, and similar workpiece materials. Each unit weighs 0.03 pounds, making it a lightweight consumable suited for detail work where a full-size flap disc cannot reach.

This microwheel is used in metal fabrication, maintenance and repair, and finishing applications where internal bores, contoured surfaces, slots, or narrow channels require controlled abrasive contact. Technicians in HVAC, plumbing, electrical, and general mechanical trades reach for wheels like this when cleaning burrs from pipe ends, conduit cuts, fittings, or machined components before assembly. The small diameter and short arbor length allow access into recessed areas that standard abrasive tooling cannot address.

Key Features

• 320 grit aluminum oxide abrasive for fine finishing and light deburring
• 3/8 inch diameter by 3/8 inch width for use in tight and contoured areas
• 1/8 inch shank fits standard die grinders, rotary tools, and flex-shaft machines
• Lightweight at 0.03 pounds per unit for reduced operator fatigue during detail work
• Flap wheel construction conforms to workpiece contours for consistent finish

Compatibility

Designed for use with rotary tools, die grinders, and flex-shaft handpieces accepting a 1/8 inch shank. Suitable for metal, composite, and similar materials requiring fine surface finishing at 320 grit.

Installation Notes

Mounting is performed by inserting the 1/8 inch shank into the collet of a compatible rotary or die grinder tool and tightening securely before operation. Always confirm the tool RPM rating is compatible with the wheel before use and ensure the workpiece is secured. Wear appropriate eye protection and follow the tool manufacturer's safety guidelines. Inspect the wheel for damage before each use and discard if flaps are torn or the shank is bent.
