عجلة يد، عمود ذيل، مخرطة طاولة

The 80mm diameter feels just right for precise adjustments without taking up too much space. It mounted cleanly on my lathe's 12mm shaft and the key fit perfectly with zero play.

The bore length of 22mm was exactly what I needed to seat it properly on the shaft, and the keyway alignment was spot on. Spinning it feels smooth and solid, no wobble at all.

I was pleased with how precisely this handwheel fits the 12 mm shaft and keyway—no slop at all. The 80 mm diameter gives enough leverage for smooth tailstock adjustments during light turning work. Only minor nitpick is the finish could be a bit more polished, but it functions perfectly for the price
