Mia ★★★★★

Slotted right into the motor mount without any filing needed. It holds the pulley firmly now, no more slipping under load.

George X. ★★★★★

Took a chance on this little motor mount key for my SC4 and it seated perfectly into the slot, no filing or fuss needed. The 5x25mm size matched the diagram exactly, and the fit in the keyway felt snug and solid right away.

Michael ★★★★★

The 5x25mm dimensions were exactly what I needed for the motor mount on my bench lathe. It slid right into place and matched part SC4-111 perfectly.
