iGaging DigiAlign digital alignment gauge indicator, new. Excellent for many uses including, checking runout on rotating devices (drill press, circular saws, planers, shapers, jointers, saw blade flatness, aligning fences, etc.), setting/adjusting height, depth, etc. Includes a miter-slot bar with adjustments to assure a perfect fit in the slot. Readouts available in Inches, millimeters, and imperial fractions. Excellent gauge, I accidentally ordered a second one. My loss is your gain. Quick mailing.
