The Mitutoyo fine spindle feeding micrometer head with 0.25mm/rev is ideal for fine adjustments and positioning of a work stage, parts holder or machine.
Features & Benefits
The Mitutoyo micrometer head with fine-feeding spindle is constructed of hardened tool steel, and the measuring face is precision lapped for better accuracy. The thimble extends at a much smaller rate, 0.25mm per revolution, than conventional micrometer heads for more precise positioning and measurement.
