1/8 X 1 X 1/4 (2 3/4"全長) 砂布套軸心 A-1

The 1/8-inch shank fits my rotary tool snugly with zero wobble, and the 1-inch wheel width handles the cartridge rolls just right for deburring. This little thing feels solid in the chuck, no complaints after a week of use.

Finally, a mandrel where the 1/4-inch arbor hole fits the cartridge rolls snugly without wobbling. The 2 3/4-inch overall length gives me just enough reach for tight spots on my die grinder.

The 1/8-inch shank fit my die grinder perfectly, no wobble at all while smoothing out a weld seam. The 2 3/4-inch overall length gave me just enough reach to get into a tight spot without swapping tools.
