1/4 X 1 X 1/4（3" OAL）卡式心軸 C-1

The 1" roll diameter is a perfect fit for getting into tight spots, and the overall length gives me good control during use. It holds the cartridge rolls securely without any wobble, which makes a noticeable difference in the finish.

I’ve been using this mandrel for a few weeks now, and the 3" overall length gives me just the right control for reaching into tight spots without wobbling. It holds the cartridge rolls securely during heavy deburring, which is exactly what I needed.

The 1/4" shank locks in solid without any wobble, which is exactly what I needed for precise work on tight spots. The 3" overall length gives me just enough reach to get into those awkward angles without feeling clumsy.
