Flap wheel dimensions and fit
This 3M interleaf flap wheel measures 3 inches in overall diameter with a 1.75 inch flap width and mounts on a 1/4 inch straight shank. The coated and non-woven aluminum oxide construction delivers a medium P120 grit finish. It is rated for a maximum operating speed of 8,000 RPM.
Best for blended finishing, not heavy stock removal
The interleaf design suits metalworkers who need to blend surfaces, remove light oxidation or prepare parts for coating in a single step. Shops that require aggressive grinding or rapid material removal should choose a conventional flap disc or grinding wheel instead.
1/4 inch straight shank compatibility
The wheel fits any die grinder, rotary tool or drill chuck that accepts a 1/4 inch straight shank. Verify that your tool’s maximum speed does not exceed 8,000 RPM before mounting.

Questions about this item
How much noise, heat or power does the 80678 flap wheel produce when running all day at 8000 RPM?
The wheel spins at up to 8000 RPM on a 1/4 in straight shank; actual noise and heat depend on the sander motor and workpiece, not the wheel itself.
What must I already own for the 1/4 in shank on this 80678 wheel to work?
A die grinder, rotary tool or drill with a 1/4 in collet or chuck that can run safely at 8000 RPM.
Will the 3 in diameter and 1.75 in width of this 80678 wheel fit the same arbor spacing as my older flap wheels?
The wheel mounts on a 1/4 in straight shank, so it fits any tool with a matching 1/4 in collet regardless of the previous wheel's diameter or width.
