Dremel 504 flapwheel
Dremel 504 uses 80-grit abrasive leaves on a 1/8-inch shank.
How to choose
Compare the flapwheel when the work has a curve or a small surface to finish. Look at working clearance separately from the tool-side shank.
Compatibility and limits
80-grit flapwheel · mounted 1/8-inch shank
Care
Choose the grit for the surface and the amount of material you need to remove. Dremel’s sanding guide separates shaping, smoothing and finishing stages.
Questions before buying
What makes the flapwheel a different choice from a sanding drum?
The abrasive leaves change how the head contacts a contour. A rigid drum is a better comparison when you need a specific refill diameter and already have that carrier.
