Frequently Asked Questions

What is a MT 3/3 extension sleeve used for and when is it necessary?

The MT 3/3 extension sleeve has an outer taper MT 3 (it fits into the machine) and an inner taper MT 3 (it holds the tool). It allows mounting tools with a Morse taper MT 3 shank on machines with a Morse taper MT 3 spindle — the larger number is the machine taper, the smaller is the tool taper. The extension sleeve allows the smaller tool to fit into the larger spindle, maintaining DIN 2187 concentricity.

Difference between an extension sleeve and a reduction sleeve?

An extension sleeve takes a smaller taper (tool) into a larger spindle (machine): MT 3/3 → the machine has MT 3, the tool has MT 3. A reduction sleeve does the opposite — it takes a larger taper into a smaller spindle. They are not interchangeable. Always check which one you need before purchasing.

How do you remove the sleeve from the Morse taper spindle?

Using an ejector pin (drawbar) that slides through the spindle hole: insert the pin from the opposite side and strike with a hammer. Alternatively, use a flat extraction wedge inserted into the spindle slot. Never force it with improvised tools — the Morse taper is self-locking, and lateral force can damage the spindle.
