Christopher ★★★★★

Replaced an old worn part on my SC4 bench lathe with this key, and it lined up perfectly with the #260 diagram reference. The 3x6 mm size feels exactly like the original, no slop or wiggle at all.

Richard ★★★★★

The 3x6 mm size is exactly what I needed for my SC4 bench lathe, and matching it to part 260 on the diagram took seconds.

Richard ★★★★★

Fits the SC4 bench lathe perfectly without any slop, and the 3x6 mm size matches the part diagram exactly. It locked right into place, so I’m glad I didn’t have to file it down.
