Starrett 762XFL Digital Micrometer Head, Non-Rotating Spindle, 0-1" Range, 0.00005" Graduation, +/-0.0001" Accuracy, Friction Thimble, Lock Nut, Carbide Face

The Starrett digital micrometer head has a digital single-value LCD readout that displays in inch and metric units with resolution to 0.00005” (0.001mm), a vernier scale graduated in inch units, and a knurled ring-type lock nut to hold measurements in place. It has a plain stem for mounting in a fixture with a split-body clamp or setscrew. The micrometer has a flat measuring face for measurement or use as a stop, and is carbide-tipped for wear resistance and micro-lapped to help provide accuracy. The micrometer is available with a non-rotating spindle to help prevent wear on the workpiece.

The micrometer’s electronic microprocessor can hold measurements at any position, convert to absolute value, set a temporary zero position, and return to a true zero reading. It also has a preset to install a reading at any position. The micrometer has Statistical Process Control (SPC) data output to transmit results to a computer or external device. The output jack transmits SPC results to a computer through an interface cable (sold separately). The micrometer includes, and is powered by, a single CR2450 lithium cell battery.

Micrometers are precision measuring instruments that use a calibrated screw to measure small distances. These measurements are translated into large rotations of the screw that are then able to be read from a scale or a dial. Micrometers are typically used in manufacturing, machining, and mechanical engineering. There are three types of micrometer: outside, inside, and depth. Outside micrometers may also be called micrometer calipers, and are used to measure the length, width, or outside diameter of an object. Inside micrometers are typically used to measure interior diameter, as in a hole. Depth micrometers measure the height, or depth, of any shape that has a step, groove, or slot. Micrometer heads are for mounting in fixtures, where they are typically used for measurement, or as stops or feeds.

The L.S. Starrett Company manufactures precision measuring tools, metrology and testing equipment, and saw blade products. The company was founded in 1880 and is headquartered in Athol, MA.
