Review on Mitutoyo 141 009 Micrometer Interchangeable Graduation by Andrew Schobinger

Bought the unit for 75% of the price so it was worth making my own extension poles (they don't come with the unit). You also need to convert millimeters to inches. It is probably best if you are a machinist or a quality control specialist to take advantage of this piece of equipment for sale. Wouldn't buy from the list!
