Spacer, Spindle 14 mm

Dropped this on the spindle of my micro mill and it fit perfectly first try — the 14 mm length was exactly what I needed to space the cutter properly. The 20 mm ID slides on smooth with no wobble, and that 4 mm keyway engaged the key without any filing.

Wasn't sure the 4 mm keyway would line up with my old spindle but it slid right on with no filing needed. The 14 mm length gives me just enough clearance for the pulley without any wobble at speed.

Fit my micro mill spindle perfectly, keyway lined up with the drive key on the first try. The 14mm length gave me exactly the spacing I needed to clear the bearing housing.
