3/16 X 1/2 X 1/8（全長 2 1/4"）砂布套筒軸心 D-1

Fits my die grinder perfectly—the 2 1/4" overall length gives me just the right reach for tight spots. Sanding drums lock on securely without wobble, which is a relief after dealing with cheaper ones.

First time I’ve used a cartridge mandrel this small and it holds the sanding bands tight without slipping, even on curved edges. Worked perfectly for deburring some tight inside corners on a metal project.

The 3/16 x 1/2 shank fits my rotary tool chuck perfectly, and the 1/8" mandrel diameter holds the cartridge snugly without any wobble. I've used it on a few projects already and it's held up exactly as it should.
