Differences between U2 and U3

[Jeff Toycen]

Difference between U2 and U3
1. U2 max clamping diameter is Ф3-16mm, U3 is Ф3-28mm;
2. The collet for U2 is spring collet, for U3 is 5C collet;
3. End mill, drill bit, lathe tool grinding attachments are actually made for U2, so if you want to use them on U3 you need to buy U2 sleeve to adjust them. I think, it’s better for you to buy U2 with all the attachments and U3 sleeve if neccessary, cause main function of these two machines are same. U3 is good for the clients, who doesn’t need any of the attachments. Also together with the machine we also can send you for free 3pcs of collets of any size on your choice. Our collets sizes for U2 spring collets – 3, 4, 6, 8, 10, 12, 14, 16; for U3 5C collets – 3, 4, 5, 6, 8, 10, 12, 14, 16, 18, 20, 22, 24, 25, 26, 28. The colours of the machines we have are yellow and green, and the voltage can be 220V and 380V.
