SMALL & FAST!

The MICRO 90 Jet Spindle, with a solid shell of titanium and assembled from only six parts, is built for powerful, accurate work in small and difficult to reach spaces.

Offering speeds from 35,000 to 45,000 rpm while the main machine spindle remains idle. Ideal for a wide range of semi-finishing and finishing applications using small cutting tools such as milling, drilling, thread-milling, engraving, chamfering and deburring.
