1/8 X 1 1/2 X 1/4（總長3 1/4吋）筒形心軸 A-2

I needed a cartridge mandrel for some tight sanding work, and this one's 1/8" shank held steady without any wobble. The 1 1/2" length was perfect for getting into corners without hitting the workpiece.

The shank fit snugly into my die grinder without any wobble, and it held the cartridge roll firmly through some heavy deburring. A solid, well-machined little mandrel that does exactly what it should.

The 1/8-inch shank fits my rotary tool perfectly and the 3 1/4-inch overall length gives me just enough reach for tight spots. Cartridge rolls stay put without any slipping, even on heavier sanding passes. Only wish it came with a spare.
