Frequently Asked Questions

What is a MT 4/2 reducing sleeve used for?

The MT 4/2 reducing sleeve has an external taper MT 4 (the tool) and an internal taper MT 2 (the machine spindle). It allows the use of tools with a larger MT 4 shank in machines with a smaller MT 2 spindle — the opposite of an extension sleeve. Fully hardened and ground according to DIN 2185.

Does the MT 4/2 reduction lose concentricity compared to direct mounting?

A quality sleeve (fully hardened, internal and external taper ground DIN 2185) introduces negligible run-out error — typically <0.01 mm — which is sufficient for 95% of standard drilling and turning operations. For high-precision grinding and boring, where concentricity <0.005 mm is critical, prefer tools with the machine's native taper.
